Optical Endstop Photoelectric Light Control Limit Switch – Plug & Play Sensor for 3D Printer

The Optical Endstop Photoelectric Light Control Limit Switch is a high-precision, noise-free end-stop sensor designed for reliable limit detection in 3D printers and CNC machines. Unlike mechanical switches, this optical sensor uses infrared beam interruption to detect the presence or position of moving components, making it more durable and silent during operation.

When the light path is blocked, the sensor instantly sends a digital signal and lights up the onboard LED, indicating that the endstop has been triggered. This plug-and-play module is fully assembled and ready to use, ideal for use as X, Y, or Z axis limit switches. With no mechanical wear or electrical noise, it boasts a longer operational life—exceeding 100,000 cycles.

🔧 Key Features

• Fully assembled plug-and-play optical switch
• Uses photoelectric interruption to detect limits
• No physical contact – ensures silent operation
• Longer lifespan than mechanical switches (100,000+ cycles)
• LED indicator turns ON when triggered
• Compatible with 3D printers (e.g. Ender, Prusa) and CNC
