The HE safety switches have up to 2 x N/O + 1 N/C bidirectional solid state outputs. When installed on a machine guard, power is applied, and the switch and actuator are within the specified operating range, the N/O Outputs will be closed, the N/C Output will be open.

The HEM40 safety switches are fully encapsulated into a 316 grade stainless steel 40mm barrel housing and available with 6 metre pre-wired cable. With a 7mm switching distance the actuator can approach the switch from most angles. When the switch is closed the targets on the printed face of the switch must be aligned.

Unlike other HE-Series products, the HEM40 does not feature LED indication.
