SM353RT Datasheet | Honeywell

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). 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...
