Magneto Resistive Sens. Digital Description

Standard Power Series omnipolar magnetoresistive sensor IC, ultra-high sensitivity (7 G typ. operate, 11 G max. operate,) flat TO-92-style, 1000 units/bulk

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.

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
