EL-138-2 / 0305331

The EL-138-2 is a solenoid replacement assembly for concealed Optima® ES (electronic solenoid) or Optima® ES-S (electronic solenoid sensor) flushometers. Optima® ES and ES-S electronic solenoids are for the Royal®, Crown®, Regal®, and Sloan®24V style flushometers. The EL138-2 solenoid assembly is intended for flushometers operating with a 24V electrical supply. The solenoid is rough-brass and is located on the opposite side of the incoming water supply. Sloan offers additional solenoids and solenoid repair parts based on your flushometer needs. 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.
