New valve sensor connects to pneumatic actuator solenoid

With compact construction and easy mounting, ifm electronic’s new MVQ201 valve sensor evaluates the valve position to the nearest degree and has an integral M12 connection that can be used for connecting to a pneumatic actuator solenoid. With this option, the valve is controlled via the same IO-Link connection used to monitor the sensor, eliminating the need for separate valve wiring and reducing installation complexity and cost.

The MVQ201 sensor continually monitors valve position and makes the position data available to the control system via an IO-Link interface. The sensor can also be programmed to detect changes such as increased opening and closing times, which might indicate valve faults or blockages, and to report these changes via IO-Link. This makes it a suitable choice for use in condition-based maintenance applications, says ifm. Conventional ‘valve-open’ and ‘valve-closed’ switching outputs are provided and can be set for either normally-open or normally-closed operation. The valve positions corresponding to the open and closed states can be programmed with a single-click auto-teach function. MVQ201 sensors also incorporate a clearly visible status LED that shows the valve position at a glance.

Suitable for use with valves having shafts of up to 35 mm in diameter as standard, the MVQ201 valve position sensors have an IP65/IP67 protection rating and an operating temperature range of -25°Celsius to +70 ºCelsius. A range of accessory mounting adaptors is available to further simplify installation and to accommodate larger diameter valve shafts.
