Overview
Magnetoresistive Sensor ICs Standard Power Series: SM351RT, SM451R, SM353RT, SM453R 32304118 Issue C SM451R SM453R SM351RT SM353RT 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-92style 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).
Datasheet 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...
