The JW Winco GN 817.7 indexing plunger is pneumatically actuated, and detects both end positions with a single sensor. The new plunger can be used in hard-to-reach locations and integrates into automated processes.
The position detection of the GN 817.7 is proven magnet technology with added innovation. Not only are both end positions now detectable, but they can also be individually defined. Upon reaching the respective end positions, the high signals are transmitted directly over the 4-pin M8 cable plug to the control unit of the system.
The GN 817.7 is made of robust stainless steel and is available in four plunger diameters and three functional variants. Type D is double acting, meaning the plunger is pneumatically retracted and extended. Types A and E are single-acting, meaning the pneumatic actuation retracts the plunger in the case of type A and extends it in the case of type E. The spring-loaded plunger always returns independently to its initial position if air pressure is lost.
The indexing plunger operates with pressures between 4 and 6 bar, while the IP 67-compliant sensor emits DC signals between 12 and 30 volts.
