📏 Optical Endstop Sensor with Cables

🧲 Non-Contact Position Detection for Precision Machines

The Optical Endstop Sensor provides accurate, non-contact end detection for 3D printers, CNC machines, and robotics. It uses a photointerrupter (infrared emitter and receiver) to detect motion interruptions, offering better reliability and longer lifespan than mechanical switches.

🔍 Features

• 🟢 Non-contact detection using infrared beam
• ⚡ Fast response time — high-speed signal switching
• 🧲 Long life — no mechanical wear
• 🔌 Pre-soldered 3-pin JST connector with 70cm cable
• 🔋 Wide voltage range: 3.3V–5V compatible
• 🛠️ Plug-and-play with most 3D printer controller boards
• 🧩 Built-in signal LED for visual feedback

🛠️ Applications

• 🖨️ 3D printer axis limit/endstop
• 🛠️ CNC machine limit detection
• 🤖 Robotics — position and motion feedback
• 🚦 Safety interlock sensors
• 🎓 Prototyping and STEM kits

⚠️ Notes

• ✅ No debounce needed — purely optical
• ⚠️ Do not expose directly to sunlight or IR light sources
• 🔄 Can be configured as normally open or normally closed via software

✨ Key Advantages

• 🧼 Dust-free operation — unlike mechanical contacts
• 🕒 Instant triggering — no delay
• 🔁 Long-lasting and reliable in repetitive operations
• 🔋 Works with both 3.3V and 5V systems
