S284 Capacitance Type Oil Level Switch with Deutsch connector

The S284 is an active device designed to give an alarm signal if liquid falls below, or rises above, a preset level. It can be specified with a delay to eliminate false alarms due to turbulence.
Containing a factory programmable microprocessor, the switch offers sink to ground or source voltage output. Its small footprint with limited intrusion into the tank means a reduced risk of damage and a wide range of customer specifiable options make it suitable for most applications.


The S284 is a horizontally mounted capacitance switch for sensing oil levels. Fitted with a 4 way Deutsch connector, all models have a factory programmable time delay to reduce the risk of intermittent switching through liquid turbulence and a wide selection of switching outputs.

Designed for use in mineral oils, typically used in engines or hydraulic actuators, compatible with brass, PTFE and FVMQ.
