Description
The Spartan is a positive mode, tongue operated guard locking
interlock switch that locks a machine guard closed until power is
isolated and ensures that it remains isolated while the guard is open.
It is available in two contact configurations: two safety (N.C.)
contacts and one auxiliary (N.O.) contact or three safety (N.C.)
contacts. The Spartan head has two entry slots and it can be rotated
to provide four actuator entry points. A blanking plug is provided to
seal the unused slot.
The guard may only be opened when a signal is applied to the
Spartan’s internal solenoid which releases the lock mechanism.
Therefore the Spartan is ideal for machines which do not stop
immediately or where premature interruption of the machine could
cause damage to tooling and components or cause an additional
hazard.
The locking mechanism withstands forces up to of 1200N (270lbs.)
and an LED provides visual indication of switch status.
A catch kit with actuator alignment is also supplied to relieve stress
on the locking solenoid and to protect the unit from actuator
damage due to poor guard alignment. Manual release points with
security screws or special key allow the locked Spartan to be released
in the event of total power failure on a machine.

Typical Applications
Note:
Lift-off guards require good alignment when using
tongue actuated interlock switches.
IMPORTANT: It must not be possible to lift the guard
without actuating the interlock. An interlock on either side
may be required.
