SS449R Datasheet PDF - Honeywell

The SS449R is an unipolar digital hall-effect Sensor IC, small, versatile digital Hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. This is designed to respond to a single pole: North (SS340RT) or South (SS440R). Its 3VDC capability allows for use in low voltage applications, promoting energy efficiency. Suitable in a variety of potential motion control, lid closure detection and displacement sensing applications.

● Simple activation from a single pole and multiple magnetic sensitivities (high, medium and low)

● Low voltage 3V capability, helps to reduce power consumption

● Built-in reverse polarity protection, protects device from potential damage during installation

● Thermally balanced integrated circuit, provides for stable operation over a wide temperature range

●ESD sensitive device, take proper precaution while handling the device.
