The HRS100 Hall-effect rotary position sensor allows programmable customization of temperature coefficient, offset and gain control at the time of manufacture. The sensor is constructed with a Hall-effect IC mounted at the center of rotation of a potentiometer-type housing and operates by rotating one or a pair of magnets around the IC. The changing magnetic field causes the output of the Hall-effect device to swing from essentially 0V to the maximum supply voltage. The sensors are most often used in applications requiring less than 180° rotation. They replace potentiometers when used as a position sensor feeding voltage-controlled equipment, but not when the potentiometer is used directly in a resistive mode such as a volume control or rheostat, two-wire device. For example, throttle control on many of today's cars are Hall-effect types and not potentiometers. Many joystick or lever type controls are being converted to Hall-effect for their greater reliability. The sensor is 1" in diameter x 1/2" deep and has a 1/4" shaft with a 3/8" bushing. Linear output voltage range can be 0% to 100%, 5% to 45%, 5% to 95%, or 10% to 90%. Operating temperature range is -40°C to 150°C.
