SICK Retroreflective Photoelectric Sensor, Rectangular Sensor, 0.1 → 15 m Detection Range

The W27 family is designed for harsh industrial environments where it copes easily with heavy vibrations, shocks and extreme temperature fluctuations. The W27-3 Ex photoelectric sensor meets category 3G/3D (ATEX) requirements for use in explosive environments. The standard also prescribes a specific mechanical stability that conventional sensors do not meet.

These sensors are enclosed in a rugged metal housing that provides users with a ready-to-install solution that complies withal its aspects. For besides limit values for temperature, performance or UV resistance.
