Linear position sensor VN1015 Series

rotarynon-contactHall effect

Sensor VN1015 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 with bipolar or CMOS logic circuits with suitable pull-up resistor RoHS compliant Typical Applications Door/gate position control Exercise equipment Printers Environmental Specifications Operating Temperature (VN101501, VN101503) -40 °C to 85 °C (-40 °F to 185 °F) Operating Temperature (VN101502, VN101504) -40 °C to 150 °C (-40 °F to 302 °F) Storage Temperature (VN101501, VN101503) -40 °C to 85 °C (-40 °F to 185 °F) Storage Temperature (VN101502, VN101504) -40 °C to 150 °C (-40 °F to 302 °F) Electrical Specifications Supply Voltage 3.8 to 24 VDC Maximum Input Voltage 30 VDC Maximum Reverse Voltage 30 VDC Supply Current 4.1 mA typ., 7.5 mA max.
