S287 Capacitance Type Liquid Level Switch – Flying Lead

The S287 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 and the flying lead enables customers to specify a suitable connector of their choice.
Containing a factory programmable microprocessor, the switch offers sink to ground or source voltage outputs.
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 S287 is a horizontally mounted switch for sensing water/coolant levels. This product differs from the S285 by offering flying leads as the means of connection with the customer’s own choice of plug or receptacle optionally available.
