Overview

The SS413A is a high-performance bipolar Hall-effect digital switch designed for magnetic sensing applications. It operates over a wide supply voltage range of 3.8V to 30V and features a temperature-compensated open collector output capable of sinking 20mA.

Why Choose This Part

The sensor features built-in temperature compensation to ensure consistent 14mT trip and -14mT release points across its operating range. Its bipolar design makes it ideal for detecting alternating north and south poles, while the wide 3.8V to 30V input range simplifies integration into both logic-level and industrial 24V systems.

Applications

Brushless DC Motor Commutation
Used to detect rotor position in BLDC motors for precise electronic commutation.
Flow Rate Sensing
Monitors the rotation of a magnetic impeller to calculate fluid flow in industrial meters.
Speed and RPM Measurement
Acts as a tachometer sensor by detecting alternating magnetic poles on a rotating shaft.
Magnetic Encoder
Integrated into rotary encoders to provide digital pulse feedback for position tracking.

Getting Started

Connect the supply voltage to pin 1 and ground to pin 2, then interface the open collector output on pin 3 to a microcontroller using a 10k ohm pull-up resistor. Ensure the sensor is oriented so the branded face is toward the magnetic field, and use a bypass capacitor near the supply pins to minimize electrical noise.
