Sloan EL645A Sensor, Brushed Stainless

The Sloan EL645A is a brushed stainless sensor, a Sloan Valve genuine replacement part.

The EL-645-A sensor assembly is a sensor replacement for Royal® Optima® ES-S (electronic solenoid sensor) and Royal® Optima® ES-S TMO urinal style flushometers. The EL-645-A sensor assembly is intended for exposed ESS-TMO and concealed ES-S urinal flushometers operating with a 24V electrical supply. The sensor plate is chrome plated and mounts onto the wall. An IR sensor is a type of sensor that detects the presence of an object or a person using infrared light. When an object or person comes close to the sensor, the IR light is reflected back to the sensor, which triggers the flushometer to initiate a flush cycle. Sloan offers additional sensors and repair parts based on your flushometer needs.

Common Questions

What flush valves does this part fit?

Sloan's own parts data does not name a specific series for this exact code. Confirm fit against your flushometer's model number before ordering, or contact CSG to verify.

Is this the same part as the unpackaged version?

Yes -- this is the individually packaged version of this part. Sloan sells the identical physical component under a related code without retail packaging; only the packaging differs.

Is this a genuine Sloan part?

Yes. The EL645A is a factory-original Sloan Valve Company replacement part, not an aftermarket equivalent.
