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).
