Unipolar Hall-Effect Digital Position Sensors

Honeywell has optimized the size of the integrated circuit, saving on manufacturing costs while still meeting customer requirements. These manufacturing cost savings result in lower costs to customers. The SS340RT Series is a subminiature device that is available on tape and reel, which allows for automated pick-and-place assembly, helping to reduce the customer's manufacturing costs. As a unipolar device, the SS340RT Series is designed to respond to a single pole (North). The SS440R Series is available in a leaded flat TO-92 style package. It is designed to respond to a South pole.

Potential applications include door or lid closure detection, speed and RPM (revolutions per minute) sensing in fitness equipment, flow rate sensing in industrial processes, appliances, or water softeners, damper or valve position control in industrial, HVAC, or residential/commercial applications, robotic control (cylinder position monitoring), float-based fluid level sensing, printer head position sensing, displacement sensor in hospital beds or medical equipment, and medication bin monitors on portable drug carts.
he SS340RT and SS440R Series' 3 Vdc to 24 Vdc supply voltage range and their ability to operate up to 150 °C [302 °F] expand application opportunities. Their thermally balanced integrated circuit provides stable operation over a full temperature range. Sinking output with an open collector allows the device to interface with many electrical components without buffering.
