Interlock Switches

Guard Locking Switches

Atlas 5

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 self-

aligning 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.
