DESCRIPTION
Honeywell’s MICRO SWITCH CPS Series Cable-Pull Safety
Switches provide a readily accessible emergency stop signal, a
cost-effective means compared to using multiple emergency
stop push-buttons. The CPS Series Cable Pull Safety Switch’s
internal mechanism latches on both slackened cable (push)
and pulled cable.
• Electrostatic, epoxy-coated, die-cast zinc housing
• Optional hardware packets available
The 1CPS is intended for use in applications where the cable
span is 76 m [250 ft] or shorter. It is an economical solution for
shorter runs or zone protection typical to automated systems.
The 2CPS Series is intended for use in very long cable runs of
152 m [500 ft] or shorter, such as long conveyor lines found in
warehouses.
POTENTIAL INDUSTRIAL APPLICATIONS
• Long conveyor systems found in warehouses and
distribution centers
• Conveyor systems with a high amount of vibration
• Conveyor systems that experience wide temperature swings
• Long conveyor systems where easy-through wiring, or highly
visible trip status, is required
• Perimeter guarding in hose-down conditions
• Packaging equipment
• Assembly lines
A line in the midpoint of the cable tension window indicates
proper cable tension, providing easy set-up. The direct opening
switch contacts are held closed when the actuating cable is
under proper tension and the reset knob is set to the RUN
position. When the actuating cable is pulled, slackened, or
broken, a cam positively opens the NC (Normally Closed)
switch contacts. The snap-action operation causes the switch
contacts to change state and mechanically latch almost
simultaneously when the cable is pulled, slackened, or broken.
The NC switch contacts remain open until the CPS is reset by
properly tensioning the cable and manually rotating the reset
knob.
VALUE TO CUSTOMERS
• Cost-effective means of providing an emergency stop signal
compared to multiple emergency stop push buttons
• Capability enhances productivity by minimizing nuisance
stops due to variations in temperature, stretch of cable over
time, or other application variables
• Direct opening of normally closed contacts when cable is
actuated
When the direct opening switch contacts open, the auxiliary
contacts also actuate (open contacts close). The auxiliary
contacts are electrically isolated from the direct-opening
switch contacts. These NO (Normally Open) contacts may be
used for monitoring or signaling.
