The HED safety switch monitors 2 adjacent doors with only one switch, saving on installation time, cabling and cost. With 2 x N/O + 1 N/C bidirectional solid state outputs along with a built in LED(s) for indication. 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 HE safety switches are fully encapsulated into an ABS or 316 stainless steel housing and available with 3, 6 or 10 metre pre-wired cable. With a 7mm switching distance the actuator can approach the switch from most angles. When both switches are closed the targets on the printed face of the switch must be aligned.
