Honeywell Magnetoresistive Sensor ICs

​Honeywell Magnetoresistive Sensor ICs, Standard Power Series, are ultra-sensitive, durable, and reliable speed or position sensors. The sensors are designed for large air gaps or small magnetic fields in standard power (typically 3Vdc to 24Vdc) applications. Honeywell's solid state design offers ultra-high sensitivity of 11G max and respond to either North or South pole applied in a direction parallel to the sensor and do not require the magnet polarity to be identified.The Honeywell Magnetoresistive Sensor ICs are durable and reliable due to magnetic solid state, non-contact, no-glass design which enhance switching capability and are cost-effective due to the sensor IC's ultra-high sensitivity. The sensor ICs also simplify design-in for wired applications due to its supply voltage range, omnipolar operation, SOT-23 and flat TO-92-style package options and wide operating temperature.
