SICK WTT12L-A2543 Laser Distance Sensor (1082473)

The SICK WTT12L-A2543 is a compact and precise laser photoelectric proximity sensor that uses optical time-of-flight technology to deliver fast, reliable measurements at distances of 100 mm to 1,800 mm. With 1 mm resolution, a Class 1 visible red laser, and both analog and digital outputs, this sensor is ideal for packaging, assembly, material handling, and conveyor applications.

Housed in a rugged IP67-rated VISTAL® enclosure, the WTT12L-A2543 features background suppression, a 12-bit analog output, and simple configuration via dual teach-in buttons.
