Honeywell SS441A Digital Hall Effect Sensor TO-92 Package

Honeywell SS441A Digital Hall Effect Sensor is a temperature-compensated digital Hall effect sensor in a compact 3-pin TO-92 package, with a 3.8 VDC to 30 VDC supply range and a digital open-collector sinking-type output.

Overview

The sensor is activated by the magnetic field from either a permanent magnet or an electromagnet. It responds to alternating north and south poles, or exclusively to a south pole. Utilising band gap regulation, it is designed to operate consistently across a wide supply voltage range.

Key Features

• Digital, open-collector sinking-type output
• Continuous output current of 20 mA, cycling up to a maximum of 50 mA
• Temperature-compensated magnetics for stable operation from -40 °C to 150 °C (-40 °F to 302 °F)
• Quad Hall IC design that minimises the effects of mechanical stress on performance
• Straight leads measuring 14.99 mm in length with 1.30 mm spacing
• Compatible with automated component placement systems

Dimensions and Weight

• Width: 3.3
• Depth: 1.5
• Height: 4.3
• Weight: 1 g

Applications

The sensor is intended for sensing and control purposes. It interfaces directly with microcontrollers, logic circuits, and other electronic components, and is suitable for numerous modern, energy-sensitive circuits.

Important Usage Notes

The sensor is classified as an electrostatic sensitive device (ESD). It must not be opened or handled except at a properly equipped static-safe workstation to prevent damage. It must not be used as a safety or emergency stop device, or in any other application where product failure could result in personal injury.
