Product Overview

The 440G-T27121 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. The Switch head has two entry slots and it can be rotated to provide four actuator entry points. A blanking plug is provided to seat the unused slot. The guard may only be opened when a signal is applied to the internal solenoid which releases the lock mechanism. This signal can be via CU1 electronic timer relays or CU2 stopped motion detectors. Therefore it 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.

  • M20 Conduit
  • 1NC + 1NO Contact Configuration
  • Rotatable Head with 4-possible Key Entry Slots
