Atlas 4 Heavy Duty with Optional Trapped Key
The Atlas 4 is a positive mode, tongue operated guardlocking interlock switch that locks a machine guard closed until power is isolated and ensures that it remains isolated while the guard is open. 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 or CU2. A heavy-duty switch, the Atlas 4 locking mechanism withstands forces up to 5500N (1236lbs.) and the die-cast alloy housing is ideal for use in harsh environments. A unique feature of the Atlas 4 is its patented self-aligning head that tolerates actuator or guard misalignment, making it particularly useful for heavy machine guards.
The Atlas 4 is designed for machines that do not stop immediately or where premature interruption of the machine could cause damage to tooling and components or cause an additional hazard. With 2 safety (N.C.) contacts and 1 auxiliary (N.O.) contact, Atlas 4 is ideal for PLC controlled machines.
