The Mechan HE-Series are coded magnetic safety switches. The HE-Series is designed to combine the ease of use and maintenance of a simple magnetic safety switch along with the improved security, performance levels and indication of an electronic safety switch.
The HE safety switches have up to 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 a 316 grade stainless steel housing and available with 5, 10 or 15 metre pre-wired cable. The LQD version is supplied with a M12 leaded connector and a 5 or 10 metre 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.
