Description
The Atlas 5 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 guard may only be opened when a signal is applied to the
internal solenoid which releases the lock mechanism. A heavy-duty
switch, the Atlas 5 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 5 is its patented selfaligning head that tolerates actuator or guard misalignment, making
it particularly useful for heavy machine guards.

The Atlas 5 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 2 auxiliary (N.O.) contact, Atlas 5 is ideal
for PLC controlled machines.
