Position switches are used to monitor the position of moving parts of machines and plants.

The robust zinc pressure diecasting enclosure resists mechanical load and is e.g. suitable for security tasks in elevator construction, in conveyor technology as well as in machine and plant construction.

Series 8074 may be used in safety circuits as the device fulfills EN 60947-5-1.

For this series there is also a belt-alignment position switch available. Here the position switch monitors the conveyor belt. Zones 1 & 2, 21 & 22
