Digital Vane Sensor VN1015 Sensors Magnetically activated digital vane sensor in a rugged, overmolded plastic housing with three pins or 3-wire flying leads Description The VN1015 sensors employ 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 Typical Applications  Mechanically interchangeable with typical slotted optical switches  Door/gate position control  Robust, high speed sensing in dirty/dusty environments  Exercise equipment  No mechanical contacts to wear out  Printers  Open collector (sinking or NPN) output can be used with bipolar or CMOS logic circuits with suitable pull-up resistor  RoHS compliant Environmental Specifications Operating Temperature (VN101501, VN101503) -40 °C to 85 °C (-40 ⁰F to 185 ⁰F) Operating Temperature (VN101502, VN101504) -40 °C to 150 °C (-40 ⁰F to 302 ⁰F) Storage Temperature (VN101501, VN101503) -40 °C to 85 °C (-40 ⁰F to 185 ⁰F) Storage Temperature (VN101502, VN101504) -40 °C to 150 °C (-40 ⁰F to 302 ⁰F) 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.
