  • Continuous Positioning Sensing for Linear Cylinder
    Parker's CPS sensor uses IO-Link (and analog signal) to enable quick, easy, precise and contactless position sensing of a piston....

  • Many applications require more than just end of stroke sensing of an actuator, but traditiona methods of continuous sensing are expensive and difficult to implement.

    Parker's CPS series of sensors require no modification to the actuator, and it comes in 5 sizes with sensing ranges from 32mm to 256mm.

  • P33 Safety Exhaust Valve
    Rapidly exhaust compressed air in the event of a fault condition and to provide monitored coverage, ensuring safe function....

  • Designed for use in conjunction with a safety relay or safety PLC for safe monitoring and fault detection, the externally monitored valve has the monitoring done via a PLC or relay which offers a size and cost advantage over internally monitored valves. The integration of a safety interface into the PLC or relay will help determined the achievable category and performance level of the control system. Customers are required to provide the logic function via the safety device. The valve will lock-out to the “safe state” if asynchronous movement of the valve elements occur which will be detected by solid state pressure sensors. To achieve the proper safety rating, the safety PLC or relay must monitor the solid state pressure sensors to ensure they are not in different states for more than 150ms. If the sensors are in different states for longer than 150ms then the programming logic must shut off power to the solenoids and consider it a fault condition. If during operation the externally monitored P33 enters a fault condition the valve will shut off. A separate reset signal must be incorporated into the logic sequence to avoid automatic restart of the valve.
