SS443R Honeywell Hall Effect Sensor

Descriptions 

SS443R Hall Effect Sensor, SS443R offers medium sensitivity, with a typical operating point of 135 G at 25 °C [77 °F]. SS443R Hall Effect Sensor is the Unipolar, digital Hall-effect sensor IC, medium sensitivity, flat TO-92-style package, bulk packaging (1000 units per bag)

What makes SS443R Hall Effect Sensor better:
• Robust IC design with ESD Class 2, reverse polarity protection, and 150 °C [302 °F] capability
• Package and sensitivity options to better match application needs
• Dependable performance – similar Honeywell sensor ICs have been tested on over 100 million operations
• Honeywell legacy and expertise – 45 years of engineering excellence and Hall effect technology experience

Potential Applications

Door or lid closure detection in appliances or electronically controlled containers
May be used recessed in the door frame with a magnet embedded in the door. The magnet activates the sensor to indicate door open or close.

Simple speed and RPM (revolutions per minute) sensing in fitness and industrial equipment
May be mounted on the motor shaft of a treadmill such that the rotating magnet pole, which rotates with the motor, activates the sensor with each revolution, producing a single digital pulse for each revolution.

Flow rate sensing in water softeners, industrial processes, and appliances
May be used with one or more magnets mounted on a paddle to measure the flow rate

Damper or valve position control in industrial, HVAC and residential or commercial applications
May be used to determine if a valve or damper is fully open or fully closed

Robotic control (cylinder position monitoring)
May be used to detect the piston’s position by detecting a magnet mounted on the piston ring located inside a non-ferromagnetic cylinder.

Level/tilt measurement
May be installed in the base of a machine with a magnet-mounted pendulum fashion over the sensor. A change in the state of the output as the magnet swings away from the sensor indicates that the machine is not level.

Remote conveyor sensing
May be mounted to the frame of the conveyor, with a magnet mounted on the tail pulley. When the magnet revolves past the sensor, it produces one output per revolution, providing an intermittent visual or audible signal at a remote location to assure stability. Any interruption of the conveyor motion will interfere with the normal signal and alert the operators.
