Product Description

SS44E Hall Effect Sensor TO92 3Pin Magnetic Sensor

Digital Magnetic Field Detection Sensor for Arduino

The SS44E Hall Effect Sensor is a highsensitivity, TO92 packaged magnetic switch designed for precise magnetic field detection. This reliable sensor features an open-collector output that pulls low when a magnetic field (south pole) is detected, making it an essential component for position sensing, speed measurement, and proximity detection applications.

Wide operating voltage: 4.5V to 24V DC
Output: Opencollector requires pull-up resistor
South pole magnetic field activates the sensor

Pin Configuration (TO-92)

PinFunctionDescription
1VCC (Power)Connect to 4.5-24V DC
2GNDGround connection
3OUT (Signal)Open-collector output

> Device marking: 44E on flat face

Pinout: Facing the flat side, left to right: 1. VCC, 2. GND, 3. OUT

Wiring Guide

SS44E PinArduino PinDescription
VCC (Pin 1)5VConnect to 5V (or 3.3V)
GND (Pin 2)GNDCommon ground
OUT (Pin 3)Digital PinWith 10K pull-up resistor

> Always use a pullup resistor (4.7K10KΩ) between VCC and OUT

Without pull-up resistor, output signal will be unreliable
Do not connect OUT directly to VCC or GND

How It Works

  1. No Magnet: Output is HIGH (due to pull-up resistor)
  2. South Pole Detected: Output switches to LOW (GND)
  3. Magnet Removed: Output returns to HIGH state
The sensor is active low - output goes LOW when triggered
Use the south pole of a magnet for activation
North pole generally does not activate this type

Output Characteristics

ConditionOutput StateExplanation
Magnet Not PresentHIGH (via pull-up)Sensor idle state
South Pole PresentLOW (0V)Sensor triggered
North Pole PresentHIGHNo activation

> Output is opencollector only pulls to ground

Pull-up resistor is required to get HIGH state
Maximum output current: 25mA sink
