S121С, Proximity sensor

Description

Proximity sensor in a cylindrical housing for non-contact measurement of displacement (range 0…5.0 mm) with an electronic unit built into the sensor housing. Output type: 4…20 mA DC, 3-wire connection. Operating temperature range from −40 to +110 °C.

Used in vibration monitoring channels of supports together with the controllers of the "Vibrobit 300" and "Vibrobit 500" systems.
