Wenglor P3EC441, Laser Distance Sensor Triangulation

These laser distance sensors work with a fine blue light beam and a high-resolution CMOS line. They determine the distance between the sensor and the object by means of the triangulation principle. Thanks to the integrated TripleA technology, the sensors offer high precision, temperature stability and material independence. This means they deliver accurate results even with objects of different materials, colors and shapes, as well as in fluctuating light and temperature conditions. The blue laser light enables enhanced performance on challenging surfaces. Settings are entered via the easy-to-read OLED display or via Bluetooth using the weCon app.

• Analog output: 4…20 mA
• Wireless settings via Bluetooth
• Graphical display for easy operation
• Measured value independent of material, color and brightness
• Rugged aluminium housing
