■
Heavy-Duty Safety Interlock Switch with Guard Door Locking
High locking force of 5,500 N
(1,236 lb.)—locks guard door
shut until machine is safe to
enter
Rugged enclosure—the die-cast
housing and stainless steel
actuator of the TL8018-5 make it
suitable for harsh environments
NEMA 4 enclosure enables the
TL8018-5 to withstand water
washdown cleaning
■
Lid-mounted status light is on
when solenoid is energized,
indicating that solenoid has
unlocked the guard door
Misalignment tolerant—the self-
aligning head on the TL8018-5
enables it to operate with con-
siderable actuator misalignment
Optional trapped key—the key
must be trapped in the lock to
enable machine operation. The
key must be rotated in order to
unlock the guard door.
■
Long life—the TL8018-5, with
its stainless steel actuator, is
designed for a minimum of one
million actuations.

Locking Force = 5,500 N (1,236 lb.) maximum.
A distance of 8 mm or less between face of
switch and face of actuator is required for switch
to lock.
2. Key rotated to open
position, which locks open
the TL8018. Guard cannot
lock and machine cannot start
up with key switch in open
position.
3. Guard can be opened only
after key is rotated
to open position.
4. Key can be used as a personnel key.
Key may be removed only when key
switch is in open position.

Applications
Typical applications are on
sliding guard doors and swinging
guard doors that must remain
locked until a signal is applied to
the internal solenoid that unlocks
the guard door.

Application Monitoring Units
SR223SMT Timer Unit
Used with machines with constant overrun. Gives
a timed delay to the lock/release signal. Failsafe
and adjustable to a range of times from 1.0
seconds up to 31 seconds.
SR125SMS Stop Motion
Sensing Unit
Used with the TL8018-5 for machines with
inconstant or variable overrun. Senses back EMF
of AC or DC motors. Failsafe and adjustable to a
range of 0.01 V to 0.10 V.
Safety Monitoring Relay Units
Safety monitoring relays ensure 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. A variety of safety monitoring relay units are
available.
