🔑 Key Features:

✔ Non-Contact Sensing – Uses an infrared (IR) optical sensor for wear-free operation (no mechanical bounce). ✔ High Precision – Detects objects with sub-millimeter accuracy, ideal for precise axis homing. ✔ Wide Compatibility – Works with RAMPS 1.4, RepRap, Smoothieboard, and most 3D printer controllers. ✔ Adjustable Sensitivity – Built-in potentiometer for fine-tuning trigger distance. ✔ Fast Response – Digital (TTL) output for instant signal recognition by the printer firmware. ✔ Easy Installation – Standard 3-pin connector (VCC, GND, Signal) for plug-and-play setup. ✔ Durable Design – Compact PCB with mounting holes for secure attachment.

📌 Applications:

• 3D Printer Axis Homing – X, Y, or Z endstop replacement for smoother operation.

• CNC Machines – Non-contact limit switching for improved durability.

• Robotics & Automation – Position detection in DIY robotics projects.

📦 Package Includes:

• 1 × Optical Endstop Module

• (Optional) Jumper wires or connectors

⚙ Technical Specifications:

🔧 Why Choose an Optical Endstop?

✅ No physical contact → No switch fatigue or mechanical failure. ✅ More precise than mechanical switches → Reduces mis-homing issues. ✅ Works with Marlin, Klipper, Repetier – Compatible with most 3D printer firmware.

Note: Some calibration may be needed for optimal performance.
