Overview

The EE-SX671 is a global standard L-shaped through-beam photoelectric sensor featuring a 5mm sensing slot and NPN open collector output. It operates on a wide supply voltage range of 5V to 24V and includes a built-in indicator for easy status monitoring during installation and operation.

Why Choose This Part

This sensor offers a fast 1ms response time and high reliability with a 100mA switching capacity. Its L-shaped Polybutylene phthalate (PBT) housing provides a robust, space-saving mounting footprint suitable for chassis installation in harsh industrial environments.

Applications

End-of-Travel Detection
Used in CNC machines and 3D printers to detect the physical limits of an axis for homing and safety.
Rotary Encoding
Detecting slots in a disk to measure rotational speed or position in motor control systems.
Package Counting
Monitoring small objects passing through the 5mm gap on high-speed conveyor belts.
Liquid Level Sensing
Detecting the presence of a float or a specific mechanical indicator in industrial tanks.

Getting Started

Connect the 5V to 24V supply to the designated terminals and wire the NPN output with a pull-up resistor if the microcontroller does not have internal pull-ups. Use a standard 4-pin connector for easy maintenance and ensure the optical axis is clear of debris for consistent 1ms switching performance.
