Overview

The EE-SX673 is a transmissive u-shaped photomicrosensor designed for industrial sensing applications. It features a 5mm sensing gap and a flexible NPN open collector output that can be configured for either Light-ON or Dark-ON operation. Operating over a wide 5V to 24V supply range, it provides a fast 1ms response time suitable for high-speed position detection.

Why Choose This Part

The sensor is highly versatile due to its selectable Light-ON/Dark-ON output logic and broad voltage compatibility. Its chassis-mount design with a built-in connector simplifies mechanical integration and maintenance in rugged environments. The 100mA output current capability allows it to drive small relays or PLC inputs directly without additional amplification.

Applications

Limit Switching
Used as an end-stop or home position sensor in CNC machinery and 3D printers.
Optical Encoding
Counting pulses from a slotted disk to determine motor speed or shaft position.
Object Presence Detection
Detecting the arrival of components on conveyor belts or within automated pick-and-place feeders.
Paper Path Monitoring
Identifying paper jams or tray levels in industrial printing and sorting equipment.

Getting Started

To use the EE-SX673, connect the Vcc (5-24V) and GND pins, then wire the NPN open collector output to a digital input with a pull-up resistor. Use the control terminal to select between Light-ON and Dark-ON logic states. Ensure the sensing slot is kept clear of heavy dust or debris to maintain optical signal integrity.
