Mechan HE Safety Switches
Description:
Mechan HE safety switches are magnetically coded, solid state non-contact safety switches for use in machine guarding applications.
Non-contact operation makes the HE switches easy to install and tolerant to misalignment. The solid state design is even more tolerant to shock and vibration, and provides single point switching which makes for a simpler and more reliable machine guard interlock.
The additional security of the coded magnetic operation along with fully sealed IP67 rating make these switches ideal for use in wet or dusty and harsh environments. The HE safety switches have been designed to connect to the SCU-1 Safety Control Unit. When installed correctly, up to 30 switches can be installed in series.
Operation:
The HE safety switch has 2 x N/O + 1 N/C bi-directional solid state outputs along with 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. When the actuator moves out of the operating range, the N/O Outputs will open, the N/C Output will close.
The HE safety switch and actuator have an 7mm switching distance and can approach each other from most angles. When the switch is closed the targets on the printed face of the switch must be aligned.
To avoid physical damage, do not use the switch and actuator as a stop, leave a 1-2 mm gap for best operation and tolerance to machine guard vibration.
