FEATURES

SM351RT

SM353RT

• Magnetic sensitivities:

SM451R

SM453R

- 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

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.

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

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.

White Goods

• Lid, door and drawer position detection

• Fluid flow detection

• 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.

• 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

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).
