Honeywell Sensing and Control's Magnetoresistive Sensor ICs, Standard Power Series, are sensitive devices designed for applications that need a durable and reliable speed or position sensor for large air gaps or small magnetic fields in standard power (3 VDC to 24 VDC) applications. Unlike reed switches and other magnetic sensors, Honeywell’s solid state design offers a sensitivity of 11 Gauss max., making it the highest sensitivity sensor in its class for standard powered applications.
FEATURES
- Magnetic sensitivities:
- Ultra-high sensitivity (SM351RT and SM451R): For applications requiring ultra-high magnetic sensitivity (7 G typical operate, 11 G maximum operate)
- Very high sensitivity (SM353RT and SM453R): For applications requiring very high magnetic sensitivity (14 G typical operate, 20 G maximum operate)
- Package styles:
- SOT-23 (SM351RT, SM353RT)
- Flat TO-92-style (SM451R, SM453R)
- Supply voltage range 3 VDC to 24 VDC
- Omnipolar sensing activates with either pole from a magnet
- Temperature range -40 °C to 85 °C [-40 °F to 185 °F]
- SOT-23 supplied on tape and reel (3000 units per reel)
- RoHS-compliant materials meet Directive 2002/95/EC
