Notes
1
This sensor body is available in a factory-sealed, non plug-in configuration (with 8-ft cable),
add 6P to listed catalog number. Example: E51SAL6P.
2
Sensor body is black. E51SCN sensor bodies are rated NEMA 4, 4X and 13.
3
This sensor accepts logic modules, as seen in chart above.
4
Repeatability of the timing cycle is ±1% at constant voltage, ambient temperature and reset time.
5
Reset time is 25 ms minimum. Rated NEMA 4, 4X and 13.
