ALLNET 4duino Optoelectronic Endstop (ALL_OY_3917)

The ALLNET 4duino Optoelectronic Endstop (ALL_OY_3917) is a high-precision limit switch designed for use with Arduino, Raspberry Pi, and other microcontroller platforms. It utilizes an infrared slotted optical switch to detect position, making it ideal for 3D printers, CNC machines, and robotics applications.

Advantages

This endstop offers reliable and fast response times with low current consumption. Its digital output (active low when triggered) simplifies integration with most control boards. The built-in power and trigger status LEDs provide immediate visual feedback, aiding in setup and troubleshooting.

Suitable for

• 3D printers (e.g., RepRap, Prusa, Creality)
• CNC machines and laser engravers
• Robotics projects requiring precise limit or homing sensors
• General microcontroller-based automation

Key specifications

• Sensor Type: Optoelectronic (Infrared)
• Detection Method: Slotted Optical Switch / Interruption
• Operating Voltage: 5V DC
• Output Signal: Digital (Active Low when triggered)
• Connection: 3-Pin Header (VCC, GND, Signal)
• Detection Gap Width: Approx. 5 mm
• Current Consumption: < 20 mA
• Indicator LEDs: 2 (Power, Trigger Status)
• Material: FR-4 PCB, Electronic Components
• Mounting: Via PCB mounting holes

Recommendations

For best results, use with a 5V microcontroller and ensure proper wiring of VCC, GND, and Signal. The endstop can be mounted using M3 screws through the PCB holes. No cable is included; use standard Dupont wires for connection.
