Hall Effect Sensors Miniature Vane > 55085 55085 With Integral Actuator Magnet Description The 55085 is a miniature hall effect sensor with integral actuator magnet. Actuation occurs when a suitable vane passes through the slot between the magnet and hall element. It is capable of switching up to 28Vdc and 20mA and ideally suited to position and limit sensing, security, linear actuator, industrial process control, and shaft rotation applications. Features • Sensor and magnet contained in • Three-pin leadout integral to sensor a single housing • Reverse/Over voltage protection • Sensor operates when ferrous vane • Built in temperature compensation passes through slot Agency Approvals Benefits Agency Agency File Number • High switching speed up to 10kHz • Operates in static or dynamic • Long life - up to 20 billion magnetic field operations • Small package size E61760 (TBD) • Unaffected by harsh environments • Simple installation Applications Dimensions Dimensions in mm (inch) • Position and limit sensing • Linear actuators • Shaft rotation sensing • Angle sensing 28.00 • Security systems • Magnetic encoders (1.102) 9.00 Activation (.354) Dimensions in mm (inch) 3.25 TYP. 22.00 Ø(.128) (.866) 3.60 (.148) 7.00 (2.76) 2.50 13.50 12.00 (.098) (.531) (.472) 8.50 NOM.
