Informazioni di prodotto e di utilizzo
ASTECH LDM42E laser distance sensor with Ethernet TCP/IP, UDP and Telnet interface: non-contact measurement from 0.1 to 150 m, uncertainty ±2 mm, visible red class 2 laser, IP65. Supplied as a set (according to the ASTECH manual: sensor, connection cable, manual and USB stick with documentation and software).
Description
The LDM42E is an ASTECH optoelectronic laser distance sensor for industrial applications with Ethernet TCP/IP, UDP and Telnet interface. Non-contact measurement based on phase comparison (amplitude modulation), with high accuracy and a high degree of independence from the object's surface; the visible red laser beam makes alignment easier. Overall measuring range from 0.1 m to 150 m: 0.1 to 30 m on almost all natural surfaces, over 100 m depending on the reflectivity of the surface or with reflectors on the object. Measurement uncertainty ±2 mm under defined measuring conditions, ±3 mm from +15 to +30 °C, ±5 mm from -10 to +50 °C; resolution 0.1 mm, scalable (standard 1 mm); reproducibility 0.5 mm. Measuring time 0.1 to 6 s, adjustable or automatic, in DT mode; fixed 0.1 s in DW mode on a white surface; 20 ms in DX mode on a white surface (maximum speed 4 m/s, maximum acceleration 2.5 m/s²). Laser divergence 0.6 mrad; beam diameter < 11 mm at 10 m, < 35 mm at 50 m, < 65 mm at 100 m; class 2 laser to DIN EN 60825-1:2014 (650 nm, red). Power supply 10–30 V DC; operating temperature -10 to +50 °C, -40 to +50 °C with optional heating; storage temperature -40 to +70 °C. High-side digital output 0.5 A with programmable threshold and hysteresis; external trigger input 3–24 V with programmable delay. Powder-coated aluminium housing, IP65, shock resistance 10 g / 6 ms (DIN ISO 9022-3-31-01-1), MTBF 30,000 hours at 25 °C, mounting with 4 M6 holes on 100 x 85 mm. Options: Viton seals (-v), integrated heating (-h), pressure regulation unit (-d). Accessories: grey attenuation filters, mounting bracket, digital display for analogue signals, protective housing, water-cooled housing, protective tube with purge-air connection, protective windows.
Integrated FastEthernet interface up to 100 Mbit/s: measurement data can be read over the network via TCP/IP or UDP, and parameterisation is carried out using the Telnet protocol (ASCII). Power consumption approx. 3.5 W (approx. 28 W with optional heating). Dimensions 198 x 96 x 50 mm, weight 800 g.
Supplied as a set (according to the ASTECH manual: sensor, connection cable, manual and USB stick with documentation and software).

Selection guide: LDM42E
ASTECH LDM42E laser distance sensor with an Ethernet TCP/IP, UDP and Telnet interface: non-contact measurement from 0.1 to 150 m, uncertainty ±2 mm, visible red class 2 laser, IP65. Supplied as a set (according to the ASTECH manual: sensor, connection cable, manual and support with documentation and software).
All LDM42 models share the same measuring principle (phase comparison, visible red class 2 laser), the same range (0.1–150 m, up to 30 m on natural surfaces, over 100 m with a reflector) and the same accuracy (±2 mm); only the interface changes for your system: Ethernet (TCP/IP) interface. Choose the model according to your PLC or data acquisition system: LDM42A-RS232, LDM42A-RS422, LDM42EI, LDM42P, LDM42PN.
Consider another series if: you need a more economical version without analogue output (LDM41); you need to measure beyond 150 m or the speed of moving objects (LDM301A, up to 3000 m); a compact short-range sensor is enough for you (LDS series).
If in doubt, contact us: our technical support will recommend the right model, interface and accessories for your application.
Integration and programming
The LDM42E is mounted with the supplied bracket or with the JWx adjustable support and is connected with the connection cable included in the set (Ethernet (TCP/IP) interface). Configuration (measuring mode DT/DW/DX, measuring time, offset, analogue output scale, switching thresholds, baud rate or network parameters) is carried out with the LDMTool software supplied on the USB stick, or with the ASCII commands described in the manual.
In applications with intense light or highly reflective surfaces, use the GFW grey filters; in dusty environments, use the PT4x-AIR protection tube with purge air; the PW4 protective glass protects the optics. For integration into PLCs, positioning systems or level control, our technical team provides wiring diagrams and configuration examples.
Calibration and repair
LDM42 laser distance sensors are factory-calibrated and need no adjustment by the user; on request we supply a calibration certificate traceable to reference distances. In the field, we recommend periodic verification against a known distance and cleaning the optics with a soft cloth; avoid pointing the laser at mirror-like surfaces and observe the temperature conditions (−10/+50 °C).
Service: RODER S.r.l. – INNOVACHECK division handles verification, calibration with certificate and repairs of ASTECH laser distance sensors in Italy. Contact us, stating the model and serial number.
