Omnipolar magnetoresistive. SOT-23, flat TO-92-style. 7 G typ., 11 G max. (SM351RT, SM451R): 14 G typ., 20 G max. (SM353RT, SM453R). 3 to 24 Vdc
Honeywell Magnetoresistive Sensor ICs (integrated circuits), Standard Power Series, are ultra-sensitive devices designed for manufacturers who need a durable and reliable speed or position sensor for large air gaps or small magnetic fields in standard power (typically 3 Vdc to 24 Vdc) applications. Unlike reed switches and other magnetic sensors, Honeywell’s solid state design offers ultra-high sensitivity of 11 G max., making it the highest sensitivity sensor in its class for standard powered applications.
The Magnetoresistive Sensor ICs, Standard Power Series, respond to either a North or South pole applied in a direction parallel to the sensor. They do not require the magnet polarity to be identified, simplifying installation and potentially reducing system cost.
