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 a single housing • Sensor operates when ferrous vane passes through slot Agency Approvals Agency Benefits Agency File Number • High switching speed up to 10kHz • Long life - up to 20 billion operations • Unaffected by harsh environments E61760 (TBD) Dimensions Applications Dimensions in mm (inch) • Position and limit sensing • Shaft rotation sensing • Security systems 28.00 (1.102) 9.00 (.354) 3.25 TYP. Ø(.128) • Three-pin leadout integral to sensor • Reverse/Over voltage protection • Built in temperature compensation • Operates in static or dynamic magnetic field • Small package size • Simple installation • Linear actuators • Angle sensing • Magnetic encoders Activation Dimensions in mm (inch) 22.00 (.866) 3.60 (.148) 8.50 NOM.
