MICRO SWITCH Cable-Pull Safety Switches 004785 CPS Series Issue 5 Datasheet FEATURES 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 Choice of three actuator configurations (2CPS) Removable contact block version available (2CPS) J-hook turnbuckle included (2CPS) E-stop option (1CPS) Low profile reset and new indicator options (2CPS) DESCRIPTION Large wiring cavity with straight-through wiring Honeywells MICRO SWITCH CPS Series Cable-Pull Safety Models avaliable without broken cable, slack-cable detection Switches provide a readily accessible emergency stop signal, a 24 Vdc or 120 Vac bright, multi-cluster high-intensity LED cost-effective means compared to using multiple emergency status indicator light available on 2CPS. Single LED on stop push-buttons. The CPS Series Cable Pull Safety Switchs 1CPS. Low profile LED (2CPS) and emergency stop button internal mechanism latches on both slackened cable (push) (1CPS) options also offered and pulled cable. Gold-plated contacts are standard on 2CPS, available on 1CPS The 1CPS is intended for use in applications where the cable Electrostatic, epoxy-coated, die-cast zinc housing span is 76 m 250 ft or shorter. It is an economical solution for Optional hardware packets available shorter runs or zone protection typical to automated systems. The 2CPS Series is intended for use in very long cable runs of POTENTIAL INDUSTRIAL APPLICATIONS 152 m 500 ft or shorter, such as long conveyor lines found in Long conveyor systems found in warehouses and warehouses. distribution centers Conveyor systems with a high amount of vibration A line in the midpoint of the cable tension window indicates Conveyor systems that experience wide temperature swings proper cable tension, providing easy set-up. The direct opening Long conveyor systems where easy-through wiring, or highly switch contacts are held closed when the actuating cable is visible trip status, is required under proper tension and the reset knob is set to the RUN Perimeter guarding in hose-down conditions position. When the actuating cable is pulled, slackened, or Packaging equipment broken, a cam positively opens the NC (Normally Closed) Assembly lines switch contacts. The snap-action operation causes the switch contacts to change state and mechanically latch almost VALUE TO CUSTOMERS simultaneously when the cable is pulled, slackened, or broken. Cost-effective means of providing an emergency stop signal The NC switch contacts remain open until the CPS is reset by compared to multiple emergency stop push buttons properly tensioning the cable and manually rotating the reset Capability enhances productivity by minimizing nuisance knob. stops due to variations in temperature, stretch of cable over When the direct opening switch contacts open, the auxiliary time, or other application variables contacts also actuate (open contacts close). The auxiliary Direct opening of normally closed contacts when cable is contacts are electrically isolated from the direct-opening actuated switch contacts. These NO (Normally Open) contacts may be used for monitoring or signaling. PORTFOLIO The CPS Series is the largest switch in Honeywells MICRO DIFFERENTIATION SWITCH line of safety switches.
