The VN1015 Series of magnetic vane sensors provides high-speed sensing in dirty, dusty environments. The units are mechanically interchangeable with typical slotted optical switches but can overcome the environmental problems that may interfere with optical switch performance.

The devices employ Hall effect sensing and a permanent magnet in two small towers, separated by a 0.135-in. air gap. The output of the devices switches when a ferrous target passes between the towers. Typical targets are linear or rotary vanes using a square saw tooth or an open slot in a solid disk or band.

The vane sensors are encapsulated in a black, glass-filled polyester housing. Termination options include pins or 6-in., 24 AWG, polyolefin leads.

Available temperature ratings are -40° to +85° C and -40° to +125° C. Supply voltage can range from 5 to 24 Vdc. The minimum supply current is 6 mA.
