Description AC 15 AC (Ue) 500V 250V 100V (le) 1A 2A 5A DC 250V/0.5A 24V/2A Maximum Switched Current/ 500V/500VA Volt/Load 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. Thermal Current (lth) 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. Max Actuation Speed 160mm/second (6.3 in/sec) Max Actuation Frequency 1 cycle/second Protection IP 67 The locking mechanism withstands forces up to of 1200N (270lbs.) and an LED provides visual indication of switch status. Conduit Entry 1 x M20 or quick disconnect style 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. 3-24 Interlock Switches Guard Locking Switches Spartan Product Selection Contacts Actuator Solenoid Voltage 24 V AC/DC Standard 110 V AC/DC 230V AC/DC Catalogue Number Safety Aux.
