The LaM distance sensors are manufactured for a wide range of specifications, so that for each application there is a suitable sensor availabl Due to the fast re the output signal (0, 1 ms, down to 40 request)this series is particularly suitable for high dynamic measurements. the high resolution (down to 0, 1 um) guarantees a reliable application for demanding measurements for quality control Description LAM-Series The optical displacement sensors of the LAM-series are designed for non-contact detection of the position or presence of objects They measure the distance of objects according to the principle of triangulation in the range of 0, 5-100 mm. the analogue output is a linear voltage representation of the deviation from the reference distance and has the range of t 10 VDC, optional 0-10V,+ 5 VDc or 4-20mA. The reference distance corresponds to the middle of the measuring range. A light spot is focused on the object to measureThe sensor transmits pulsed light, thus the signal is mostly independent of ambient light The diffusely reflected light spot is directed to a PSD through a lens. The intensity of the light source is adjusted automatically according to the reflectance of the surface If the intensity of the reflected light is too low, failure F1: not enough light"is displayed Highly reflective surfaces, which reflect the transmitted light directly into the PSD, will lead to failure F2: too much light. Both failures are displayed by separate LEDS and reported as logical output signals. As additional information on the lighting conditions a voltage output of the light intensity is available The output voltage "distance"at Pin 1 is directly proportional to the object distance Distance limits for the object distance can be with two comparators to distinguish between too close /oK/ too far LEDs display the present status with 3 optional relay outp available Self test A continuously running built-in mechanism guarantees the permanent monitoring of the intensity of the reflected light to check whether the object is located within the measuring range Response time and frequency range The rise time of the output signal of the laser sensors is exceptionally fast. It averages to 100 us for the LaM to reach >90% of the final value(or 40us on request). The rise/ integration time can be increased to 0. 2, 2 or 20 ms by DIP switches inside the electronic module. This reduces the noise level and improves the accuracy of the measurement For a precise adjustment of this integration time both switches of the respective time have to be set on ON(see chart), all other switches on OFF Mounting the sensor head To achieve optimal results it is important to mount the sensor in a 90 angle to the object surface, otherwise the path of the laser beam is elongated The lAM laser head should be mounted in such a way that the laser beam cannot be directed or retlected in the human ey The visible warning label (included in delivery) should be installed close to the sensor To adjust the sensor the LEDs MiN, oK and mAX may be used At the delivery MIN and MAX values are preset on the measuring range limits. As long as the OK-LED is illuminated, the object within the measuring range and reflects enough light The zero voltage adjustment should be done mechanically first, then, for fine tuning the zero-potentiometer R4 may be used, which can be adjusted with a screwdriver to approx. +5 of the range For an alignment of the different slopes of the output characteristics due to specific object surfaces, the amplification-potentiometer R5 may be used Waukon positionsesste hni k Description LAM-Series Surface related measurement deficiencies Impairment by materials and colours The objects to be measured can be made of nearly all materials, e.g. metal, plastics, ceramics, rubber and paper. Only the application with highly reflective objects or liquids should be subject to special consideration Reflectance of the surface The sensor needs a minimum diffuse reflection of 10% to perform correctly. Diffuse reflection only is usable for measurements Stray light The projected light beam results in a small amount of stray light, which will be reflected by the object surface around the light spot and received by the sensor Highly reflective surfaces around the light spot may cause the stray light to be directly reflected into the sensor and errors can occur Homogeneous surfaces with consistent reflecting properties do not cause such failures. If the shiny area is outside the light spot, failures are 2% Penetration of the light beam into the object Transparent plastic or cloudy liquids will allow the light beam to penetrate up to a certain depth, before being reflected. This depth has to be added to the measured distance and can only be verified by some additional experiments with the material Striped objects For objects with light/dark stripes(e.g. wood)the sensor should be mounted with its optical centre line parallel to the stripes (see sketch ) Due to their smaller light spot LAM/ LASER sensors are most suitable for these applications Bright /dark contrast within the light spot If there are surface areas with different reflectances joining at the light spot, the maximum light is not reflected from the centre of the spot and thus measurement errors may occur. However, this influence is minimised if the transition boundary lies parallel to the optical axis(see sketch) Changes in reflection intensity during measurement The amount of light emitted from the laM will automatically be adjusted to the reflective properties of the materials Angle dependence of measurements There is a small angle dependence if the sensor is no mounted at right angles with the abject surface. This dependence is very small for mat surfaces with high diffuse retlection and slightly greater for shiny surfaces An off-axis angle from axis a of up to 30 does not result in a significant measurement error, from axis b a rotation of up to possible Rota ion axis The measurement error arises as a changing of the A relationship between output voltage and distance If the angle of rotation is constant, it can be eliminated by readjusting the o bject surface values B Waukon positionsesste hni k Technical data LAM-Series ype LAM-O.5 LAM 2 LAM 10 LAM-20 LAM50 LAM100 Range 23,75.24,25m23..25m 40.50mm 55..75mm 95145m170.270mm Resolution 0,2pm 0, 4 um 5μm 9 um 30 um 60 um Linearity ±4pm ±20pm ±40ym ±100μm±200m Res ponse time 0,1ms;0.14ms;025ms;1ms;4ms;10ms;40ms;67ms Sample frequency k上L Sw itching output MIN (LED yellow MAX (LED orange ) OK(LED green ) 24V/10 mA Current consumption 10 ma (not available for Relay option) Power indicator LED green Alarm indicator LED red (too much light) Reflected light 0to10 Pow er supply 24VDC/200 mA(10 bis 30 V Humidity up to 90 RH Light source Laser diode, red, pulsed Laser class Wave lengt 670nm isolation voltage 200 VDC, ov ground to housing Max, vibration 5 g to 1 kHz(20 g optional) Housing material Al umn‖um Protection class P64(sensor)IP40(electronics) Working temperature 0.+50℃C Beam type ser(O) 0,1 mm 0, 2 mm 0,6mm 0.9 mm,5 mm 1,5 mm Output Analogue output ±10V;4-20mA;Rs232 Impedance approx. o Ohm Temp. coefficient 0,02%/°K External electronics inclusive The technical data (for linearity and response time) applies to a mat white object surface Pin connection electronic module LAM with 24V output Dip-switches Pin SW1 Function RS 232 Software Trigger with RXD Distance output,±10 off durationmode stopp with rts Not enough light, +24V/10 mA Laser OFF0v SW2 Function 4 TXD On Rs 232 transfer rate 38.4 kBaud Range OK, output, +24 V/10 mA Off RS 232 transfer rate 115.2 Kbaud 4-20mA RXD SW3 ut of 8 0 V supply SW4 SW5 SW6 F/ kHz T ms 14 Analogue output GND Or 16 MAX +24V/10 mA 0,1 Off on 17 Sensor 2, input 0,14 O off 18 RTS 0,2 Off on 19 M|N,+24V/10mA off 0.25 20 Light intensity 0-10) Off off 0.1 21 24 V supply On off Off O升f 67 Connector type: 25pin D-connector SW7 SW8 Function norma -laser off, if /0= gnd Off on Trigger with 1/0=GND On off Sensor Master ff off Sensor= Slave Waukon djustment 4 kHz Technical drawings LAM sensor heads Sensor head type 50/100 Sensor head type 2/10/20 Sensor head type 0, 5 21 ab le 4 4 M4 2 m cable output: sensor-electronics Electronic circuitry LAM electronic module 102 27,5 92 Sichtseite ⊕⊕蛋⊕ ( Waukon positionsesste hni k Accessories LAM-Series LAM-SG-S1 LAM-SG-T1 Compressed air Sensor head Sensor head Holes for m4 screws for M screws 一一一 Beam output Beam output LAM-SG-S2 LAM-SG·T2 119 Cable Sensor head Sensor head e 23,5 23,5 Beam output Beam o Protection housing for LAM sensors For applications at a high pollution level or te 50° c a protection h should be There are housings with an air cooling system with an airstream that prevents any dust from entering through the shelter opening LAM-SG-S1 Protection housing for LAM-2/10 with scratch resistant glass window for applications at a high pollution level LAM-SG-S2 Protection housing for LAM-50/100 with scratch resistant glass window for applications at a high pollution level LAM-SG-T1 Protection housing for LAM-2/10 with air connection for temperatures up to 50oC LAM-SG-T2 Protection housing for LAM-50/100 with air connection for temperatures up to 50C positionsmeste hii k
