EE-SX771A
Overview
The EE-SX771A is a compact L-shaped photomicrosensor designed for precise through-beam optical sensing with a 5mm sensing distance. This NPN open-collector sensor features a thin profile and a dual-sided indicator lamp, making it ideal for space-constrained industrial automation and position detection tasks.
Why Choose This Part
The sensor supports a wide supply voltage range from 5V to 24V DC, allowing direct integration with most PLC and microcontroller logic levels. Its L-shaped design and M3 screw mounting simplify installation in tight vertical spaces, while the dual-visible indicator ensures easy status monitoring from multiple angles.
Applications
Key Specifications
Getting Started
Connect the wire leads to a 5-24V DC power source and wire the NPN open-collector output to a digital input with a pull-up resistor if one is not integrated into your controller. Ensure the chassis is secured via the M3 mounting hole for proper optical alignment of the 5mm sensing slot.
