Fibre-optic sensor FMS 18 / FMS 30 / FSG 30 
Sensors for glass fibre adaptation – robust, strong, reliable
FMS 18 The FMS 18-4 U fibre-optic sensor operates at minimum to medium switching distances and ranges. The device is particularly suitable for reliable non-contact detection in rapid processes as a result of its high switching frequency of 1 kHz. Despite the device’s small size, its output signal can be inverted by using a plug-in bridge on the front. The sensor also has two separate outputs: P- and N-switching.
