Honeywell Magnetoresistive Sensor ICs - Standard

Product Announcement from Honeywell Sensing and Internet of Things


New Options Added To Portfolio!

Honeywell is pleased to announce an addition to our Magnetoresistive Sensor IC portfolio – the Standard Power Series.    These sensors are designed for manufacturers needing durable and reliable speed or position sensing for large air gaps or small magnetic fields in standard power (typically 3 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 and a cost-effective, flexible solution for position or speed sensing.

FEATURES:

  • Durable and reliable:  due to magnetic solid state, non-contact, no-glass design which enhance switching capability
  • Simplifies 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 range
  • Magnetic sensitivities - Choose:
    • 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

POTENTIAL APPLICATIONS:
