## Overview

The A3144 Hall Effect Sensor is a compact, high-sensitivity magnetic detector designed for industrial, automotive, and hobbyist applications. Operating reliably across a broad voltage range (4.5V to 24V) and extreme temperatures (-40°C to 150°C), it offers fast, spark-free switching with solid-state durability. Sold in a convenient pack of 30, it’s the go-to choice for professionals demanding accuracy, longevity, and bulk availability.

## Description

The A3144 is a digital output hall sensor, which means if it detects a magnet, the output will go low, otherwise the output will remain high. Specification: Power supply voltage VCC: 24V; Output reverse breakdown voltage Vce: 50V; Output low current IOL: 50mA Limit parameters (25 degrees Celsius); Storage temperature range TS: -65~150 degrees Celsius Working temperature TA: E: -20~85 degrees Celsius L: -40~150 degrees Celsius Function of the A3144 Hall Effect Sensor 1.Extreme stability and temperature characteristics for automotive or industrial applications 2.4.5 V to 24 V operating voltage...requires regulated power supply only 3.Open collector 25 mA output...compatible with digital logic 4.Battery reverse connection protection 5.Can detect small permanent magnets sold on the market 6.Solid state reliability 7.Small volume 8.Resistance to physical stress Package includes: 30 x A3144 3144E OH3144E Hall Effect Sensor Switches

Review: Good quality - A good quality product that function effectively.
Review: Fast delivery - Not much you can say about a hall sensor but these arrived next day and seem to have good response curve. I am not using them for anything serious just testing for project I am working on .

Not much you can say about a hall sensor but these arrived next day and seem to have good response curve. I am not using them for anything serious just testing for project I am working on .

### ⭐⭐⭐⭐ Buy if you know what you are doing.
*by H***Y on 19 March 2025*

Bought these to try and repair a burnt out throttle. In the end it was cheaper to buy a new throttle. I may find a uses for these as sensors in another project.
