Note: UL-listed models have the -US suffix. (Example: E3JM-10M4-US). 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.
*Values in parentheses indicate the sensing distance when using E39-R2 Reflectors.
