DESCRIPTION

The 2.7 Vdc to 7 Vdc supply voltage range allows this device

to be used in low voltage applications. The SS345PT’s very

small size requires less PCB (printed circuit board) space,

allowing it to be used in smaller assemblies.

The SS345PT/SS445P sensors are small, versatile digital Hall-

effect devices that are operated by the magnetic field from a

permanent magnet or an electromagnet, designed to respond

to a single North pole (SS345PT) or South pole (SS445P).

These sensors are available in two package styles: the

SS345PT in the subminiature SOT-23 surface mount package;

the SS445P is available in the leaded, flat TO-92-style

package.

These unipolar sensors are designed to meet the requirements

of a wide range of potential applications. The internal pull-up

resistor often eliminates the need for external components,

further helping to reduce the system cost. These economical

unipolar sensors are well suited for simple, high-volume, cost-

sensitive position and motion sensing applications.

The SS345PT is available on tape and reel (3000 units per

reel); the SS445P is available in a bulk package (1000 units

per bag).

FEATURES

POTENTIAL APPLICATIONS

Commercial:

Subminiature package size (SS345PT) uses less space on

the PCB than standard Hall-effect sensor packages such as

TO-92 or SOT-89, allowing for use in smaller assemblies

Tape and reel packaging (SS345PT) allows for automated

component placement, helping to reduce manufacturing

costs

Door or lid closure detection in appliances

Speed and RPM sensing in fitness equipment

Flow rate sensing in appliances and water softeners

Damper or valve position control in HVAC equipment

Printer head position sensing

Industrial

Small, flat TO-92-style package (SS445P) is also available

Simple activation from a North pole (SS345PT) or a South

pole (SS445P) makes these products suitable in a variety

of potential applications such as motion control, lid closure

detection, and displacement sensing

Flow rate sensing in industrial processes

Robotic control (cylinder position monitoring)

Float-based fluid level sensing

Medical

Displacement sensor in hospital beds and medical

equipment

Medication bin monitor on portable drug carts

Built-in pull-up resistor can easily interface with common

electronic circuits without adding external components,

helping to reduce total system cost

RoHS-compliant materials meet Directive 2002/95/EC
