Mechan HE safety switches are magnetically coded, solid
state non-contact safety switches for use in machine guard-
ing 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.
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.
(See page 3 for LED Indication.)
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 ac-
tuator as a stop, leave a 1-2 mm gap for best operation and
tolerance to machine guard vibration.
Interlocked guards where additional security required.
Door locking is not required.
Harsh environments where vibration, water or dust are
problems.
