SICK Retroreflective Photoelectric Sensor, Compact Sensor, 0.03 → 22 m Detection Range

A distinguishing feature of the W34 product family is the rugged ABS plastic housing where all control elements are in a protected location under the “optics cover”. As a result, these sensors can also be used for outdoor applications. Especially for harsh and extreme ambient conditions, we recommend using the zinc die cast housing (W24-2 product family). The sensors are equipped with minimum set of functions to reduce the variety of devices and consequently the storage requirements. Furthermore, this device design comes in DC and DC/AC variants. The W34 product family includes photoelectric proximity sensors with background suppression, photoelectric retro-reflective sensors, and a through-beam system.

The photoelectric proximity sensors are characterized by their high precision at long distances as well as their high ambient light immunity.

Rugged plastic or zinc die cast housing (W24-2)
Control elements are protected under an optics cover
High ambient light immunity and no interference when mounting the photoelectric proximity sensors opposite one another
NPN/PNP mode toggle
Light/dark mode toggle
Variants for 10 … 30 V DC or 12 … 240 V DC / 24 ... 240 V AC voltage supply
Optional: test input, time stages and contamination warning
M12 male connector or M16 screw connection, both rotatable by 90°

Very good chemical resistance increases the service life
Control elements under the “optics cover” provide flexibility as well as best possible protection in the application and reduce the
variety of devices and therefore storage requirements
Operational safety in ambient light and when devices are mounted opposite one another
Highest availability thanks to the very high operating reserve of the photoelectric sensors and through-beam photoelectric sensors
Assembly compatibility - DC devices and DC/AC devices available in the same design
