Technical content

Programmable, full 0-360 ° detection Contact less angular position sensor capable of continuous rotation

Description

Sensor is operated by rotating a magnetic actuator close to its sensitive face. Output voltage varies according angular position of the magnet. Optimal performance is achieved with Cherry’sAS500106 magnetic actuator.

Applications

 Replacement for smart bearings  PRNDL switch for harsh environments  Steer wheel position for drive by wire systems  Throttle position sensor  Pedal position sensor  Non contacting Potentiometer Dimensions mm Features and Benefits  Angular position sensor with high tolerance for misalignment  Provides non-contact angular position sensing to full 360° rotation  No mechanical interface means no parts to wear out  Sealed design exceeds IEC529 IP68 standard for immersion  5VDC ratiometric device.  Performs with AS500106 standard magnetic carrier  Provided with EMI/ESD protection to SAE J1113 standards  Maximum operating temperature of 150ºC Custom Options (Contact factory for minimums and availability)  Linear output over specific angular rotation ranges available on request  Sensor can be programmed for use with custom magnets  Custom programming option for rising or falling output slope with selectable offset, gain, clamp voltage  PWM output option available for custom applications
