Permanently reliable Wear-free due to non-contact inductive switching principle. Long service life since only corrosion-free materials are used. Ready for operation in no tim Coordinated fixing accessories for quick mounting. LEDs on the sensor indicate the valve position. The position indicator on the target puck ensures that the valve position can also be clearly seen at a distance. Corresponds to the German standard VDI/VDE 3845 for uniform connection points on actuators.

For industrial applications For hazardous areas Detect two positions with one sensor The valve sensor principally consists of two inductive sensors arranged on top of each other in one housing. Depending on the orientation of the target puck, the upper or the lower sensor switches. Advantage: The system operates without contact and is absolutely free of wear. This ensures maximum reliability and a long service life. The target pucks are available in two designs: either for standard applications with targets offset by 90 ° or with an adjustable switch angle. Premounted damping elements...

Position feedback on pneumatic quarter-turn actuators with AS-i connection Simple: Modular System solution AS-i is a manufacturer-independent standard for bus connections of actuators and sensors of the first field level. ifm offers AS-i as an all-in-one solution. The sophisticated AS-i technology provides high reliability and machine uptime. structure and flexible connection technology ensure easy integration into the AS-i system. A two-wire flat cable transmits data and energy, eliminating complex parallel wiring. Inductive valve sensors with AS-i connection The bus cabling with...

Position feedback and valve control The ifm valve sensors of the T family are used for position monitoring and for controlling pneumatic valve actuators via solenoid valves. Up to two input and output signals are transmitted via a 2-wire bus cable to the AS-i master using AS-i at a lower cost than Stainless steel insulation displacement connector conventional wiring. With only one AS-i ProcessLine module master up to 62 actuators and solenoids can be monitored and switched. For diagnostic purposes, wire break and short-circuit at the valve are monitored. This provides additional safety....

Continuous position feedback on rising stem valves AS-i integrated: The AS-i communication system is ideally suited for feedback from several valves. efector valvis is therefore also available with integrated AS-i interface. Freely programmable: efector valvis signals the valve piston position via three switching outputs: valve open, valve closed and any interim position, e.g. for the detection of seat lift or seal wear. Easy set-up: Uncomplicated programming by pushing a button replaces mechanical adjustment to the respective valve positions. Different adapters: ifm offers adapters for...

For industrial applications Precise monitoring of rising stem valves efector valvis resolves the stem travel down to 0.2 mm. Within the measuring distance three valve positions (e.g. up, closed, seat lift position) can be set via a pushbutton. In the analogue version efector valvis transmits the whole measuring distance to the PLC via a standard analogue signal. Thanks to the high resolution the sensor detects beginning of seal wear, for example. This means that it can be used for condition-based maintenance. The valve position is continuously measured and converted into a highly...

For hygienic and wet areas For hazardous areas End position monitoring on rising stem valves The end positions of rising stem valves are often monitored by inductive sensors. They provide a high protection rating (up to IP 68 / 69K) and are designed for a wide temperature range so that they also withstand high-pressure steam cleaning processes without any problems, for example. Small sensor tolerances allow precise position detection. Installation is possible above or underneath the actuator, open or in the housing. To minimise wiring, the use of the AS-i bus system is a good choice....

For industrial applications For hazardous areas End position feedback for hand valves and ball valves This mounting set makes it easy to fit feedback sensors to manually activated valves. A large number of sensors and pucks can be used on the 80 x 30 mm actuator interface to VDI/VDE 3845. The entire system can be used at ambient temperatures from -30...80 °C. Versatile and flexible The upper part is made of Vestamid and allows operation in hazardous areas. The lower part fits on many ISO flange valves (DIN EN ISO 5211) and is connected to the valve shaft by a shaft extension. Stainless...
