Description
Employs a Hall Effect digital vane sensor and a permanent magnet in two small towers, separated by a 3.4 mm (0.135”) air gap. The output 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
Features
Mechanically interchangeable with typical slotted optical switches
Robust, high speed sensing in dirty/dusty environments
No mechanical contacts to wear out
Open collector (sinking or NPN) output can be used
