SS552MT Datasheet | Honeywell

FEATURES - High sensitivity: 25 Gauss maximum operate point allows for extended sensing distance or a smaller magnet - 3.8 Vdc to 30 Vdc supply voltage range - Omnipolar sensing: Activates with either North or South pole - Temperature range: -40 °C to 150 °C [-40 °F to 302 °F] - Digital current-sinking output - Ro Hs pliant, meets Directive 2002/95/EC DESCRIPTION The 2SS52M Series Digital Magnetoresistive Sensors are omnipolar, solid-state sensors with a built-in magnetoresistive bridge integrated on silicon and encapsulated in a plastic package. The integrated circuit also includes a band-gap regulator and a digital output in response to very low magnetic fields. These sensor ICs may be operated with either a North or a South magnetic pole applied in parallel to the sensor IC. The polarity does not need to be identified, simplifying installation in single pole applications and doubling the resolution in rotating magnet applications. These small and highly sensitive omnipolar devices have bee a popular building block for flow metering, motor RPM and cylinder position sensing. They are available in five package styles: - 2SS52M: U-pack, 3-pin, in-line sensor IC with straight leads supplied in bulk packaging (1000 units per bag) - SS552MT: SOT-89B surface-mount sensor IC supplied on tape and reel which allows for pact design with automated ponent placement (1000 units per tape and reel) - 2SS52M-S: U-pack, 3-pin in-line, surface-mount sensor IC supplied in bulk packaging (1000 units per bag) - 2SS52M-T2: U-pack, 3-pin, in-line sensor IC with formed leads supplied in ammo pack tape-in-box (5000 units per box) - 2SS52M-T3: U-pack, 3-pin, in-line sensor IC with straight leads supplied in ammo pack tape-in-box (5000 units per box) 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...
