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.

Application Details
CU 2 Stop Motion Detector Unit
Used with Atlas for machines with constant or
variable over run. Gives a timed delay to the
lock/release signal. Fail safe and adjustable to a
range of times from 0.1 seconds up to 40
minutes. For more details, see the Monitoring
Safety Relay section in this catalogue.
CU 1 Timer Unit
Used with Atlas for machines with constant
overruns. Gives a timed delay to the lock/release
signal. Failsafe and adjustable to a range of
times from 0.1 seconds up to 40 minutes. For
more details, see the Safety monitoring relay
section in this catalogue.
Minotaur MSR6R/T Monitoring
Safety Relay Unit
Ensures a maximum level of safety by monitoring
all wiring in the safety circuit including switches
and contactors.
Any fault and the power to the machine is
switched off.
Other Minotaur units are available, see the
Safety monitoring relay section in this catalogue.
