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.

Note: An external pull-up resistor is required, the value of which is dependent on the supply voltage. The resistor should be
connected between the output and Vcc. Refer to the wiring diagram for lead colors or pin numbering as applicable.
