MAGNASAFE SS-C safety switches are electronically
operated non-contact safety switch for use in machine
guarding applications.
The non-contact operation makes the SS-C easy to install
and tolerant to misalignment, providing a simple reliable
solution to machine guard interlocking.
The electronic switching provides additional security and a
single point switching, leading to a more reliable and secure
long term switching solution. The switch and actuator are
IP67 rated and can be used in wet or dusty environments.
CE Complies with the relevant sections of the CE
marking directive.

Thee SSC is designed for use with ‘low inrush current’ safety
relays, maximum switching for long life performance is
500mA.
When installed on a machine guard, power is applied, and
the switch and actuator are within the specified operating
range (See table on page 4 for switching distances). The
Safety Contact will be closed and the Auxiliary Contact will
be open. The dual colour LED will be GREEN.
When the actuator moves out of the operating range, the
Safety Contact will open the Auxiliary Contact will close for
indication. The dual colour LED will be RED.
The SS-C safety switch and actuator have a 10mm switching
distance 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, set a 2 mm gap for
best operation and tolerance to machine guard vibration.
