1 / 8 page Sensing and Productivity Solutions Datasheet Magnetoresistive Sensor ICs Standard Power Series: SM351RT, SM451R, SM353RT, SM453R DESCRIPTION Honeywell’s 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. VALUE TO CUSTOMERS • Durable and reliable due to magnetic solid state, non-contact, no-glass design which enhance switching capability. • Cost-effective and flexible due to the sensor IC’s ultra-high sensitivity—the highest sensitivity sensor in its class for standard powered applications—which lowers the customer’s cost of magnets and simplifies design-in. • 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. DIFFERENTIATION • Ultra-high sensitivity (SM351RT and SM451R) allows for potential use in applications requiring ultra-high magnetic sensitivity (7 G typical operate, 11 G maximum operate). 32304118 Issue B SM351RT SM353RT SM451R SM453R 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 POTENTIAL APPLICATIONS Industrial • High frequency flow sensing in HVAC, water, fuel meters, and gas utility meters • Anti-tamper detection in water, electric, and gas utility meters • Liquid level detection • Motor RPM sensing • In-cylinder position sensing Medical • RPM sensing in exercise and rehabilitation equipment • Magnetic interrupt in exercise and rehabilitation equipment • Absence/presence detection in infusion pumps • Position sensing of medication dispensing cabinet drawers • Incline position sensing in hospital beds White Goods • Lid, door and drawer position detection • Fluid flow detection • Liquid level detection PORTFOLIO Honeywell’s Standard Power Series join: • Magnetoresistive sensor ICs, including the Nanopower Series, 2SS52M Series, SS552MT Series • Hall-effect sensor ICs, including the SS351A, SS451A |
