Note: UL-listed models have the -US suffix. The model number for an E3JM Through-beam Sensor ends in “-US” (and not in “-N”). (Example: E3JM-10M4-US). The
model number for an E3JK Through-beam Sensor has “-US” after “-N”. (Example: E3JK-5M1-N-US 2M). Tightening nuts, washers, and rubber bushings are not
provided with these models.
Change: Shape of the E3JM conduit socket
Note, however, that DC-type E3JK SSR Output Models are not UL-listed.
*1. Through-beam Sensors are sold in sets that include both the Emitter and Receiver.
*2. Values in parentheses indicate the sensing distance when using E39-R2 Reflectors.
