SM351RT Description

Short technical summary and product information.

The Honeywell SM351RT is a magnetoresistive sensor IC from the Standard Power Series, designed for reliable speed or position sensing in applications with large air gaps or small magnetic fields. It operates within a wide supply voltage range of 3 Vdc to 24 Vdc and features an open collector output.

 

This sensor offers ultra-high magnetic sensitivity, responding to either a North or South pole, which simplifies installation and can reduce system costs. Its solid-state, non-contact design enhances switching capability and durability. The SM351RT is housed in a compact SOT-23-3 package suitable for surface mounting.

 

Key specifications include an operating temperature range of -40°C to 85°C, an operating current of 5mA, and a sensing range of ±1.1mT Trip and ±0.2mT Release. The technology used is magnetoresistive, providing omnipolar switching functionality.

 

Potential applications include industrial uses like flow sensing, anti-tamper detection in utility meters, liquid level detection, and motor RPM sensing, as well as medical equipment and white goods for position detection.
