Line safe switch - CPS series

CPS Series Cable Pull Safety Switches provide a readily accessible emergency stop signal. This is a cost-effective means compared to using multiple emergency stop push-buttons. (Cable Pull Safety Switches are not, however, to be used as a means of personnel safeguarding. They may be used to prevent further injury or damage to
equipment when used for emergency stop signaling.
The CPS Series Cable Pull Safety switch is designed to provide emergency stop protection for exposed conveyor and assembly lines. The internal mechanism latches on both slackened cable (push) and pulled cable. This capability also enhances productivity by eliminating nuisance stops due to variations in temperature, stretch of cable over time, and other application variables..
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.



•Direct opening action of NC (normally closed) contacts
•2CPS: 2NO/2NC, 1NO/3NC or 4NC contact configurations 1CPS: 1NO/1NC, 2NO/2NC, 1NO/3NC or
4NC contact configurations
•Typical cable span of 76 m (250 ft) in an environment with a temperature change
of ±17°C (±30°F). Longer spans are possible depending upon temperature change and installation
(ref. note on page 6 for more details or Application note - Effect of Temperature on Cable Pull Switch Operation)
•Choice of three actuator configurations (2CPS)
•Removable contact block version available (2CPS)
•Large wiring cavity with straight-through wiring
•24 Vdc or 120 Vac bright, multicluster LED status indicator light available on 2CPS. Single high intensity LED on 1CPS
•Gold-plated contacts are standard on 2CPS, available on 1CPS
•Die-cast zinc housing
•Optional hardware packs available

Typical applications:
•Long conveyor systems found in warehouses and distribution centers
•Conveyor systems having 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
•Hose down conditions
•Packaging equipment
•Assembly lines
