4-Axis PNP NC Inductive Limit Switch Assembly with RJ45 Connection

4-Axis Inductive Limit Switch PNP NC Assembly to RJ45

This 4-Axis Inductive Limit Switch Assembly provides a clean and reliable way to add homing and limit switch detection to your CNC machine. Designed with PNP Normally Closed inductive sensors and an RJ45 connection, this assembly helps simplify wiring while giving your CNC system accurate position reference and safer travel limits.

Instead of wiring each sensor from scratch, this assembly gives you a more organized plug-and-play style connection for compatible CNC controller boards. It is available in multiple cable lengths, making it useful for compact CNC routers, larger machines, automation systems, and retrofit builds.

Why Choose This Limit Switch Assembly?

• Supports up to 4 axes: Designed for machines that need limit or homing detection across multiple axes.
• PNP Normally Closed sensor setup: NC wiring is commonly preferred for CNC safety because a broken wire or disconnected sensor is easier to detect than with normally open wiring.
• Inductive detection: Inductive sensors detect metal targets without physical contact, reducing mechanical wear compared with lever-style limit switches.
• RJ45 connection: Uses an RJ45 connector for a cleaner, faster connection to compatible CNC controller boards.
• Cleaner control box wiring: Helps reduce loose wiring, wiring mistakes, and messy sensor connections.
• Multiple cable lengths: Choose the length that best fits your machine size and control box location.
• Useful for homing and limits: Helps the CNC machine find its reference position and helps prevent overtravel during operation.

Available Cable Lengths

• 6 ft cable option
• 12 ft cable option
• 30 ft cable option

Main Features

• Suitable for CNC, automation, and robotics applications

Customer-Friendly Explanation

Limit switches tell your CNC machine where each axis is and help prevent the machine from moving too far. Homing switches allow the machine to return to a known starting position, while limit switches help protect the machine from overtravel.

This assembly makes that wiring much easier by combining multiple inductive sensors into a clean RJ45-style connection. It is a good choice if you want a more professional-looking CNC wiring setup without having to build the full sensor harness from scratch.

Common Uses

• CNC router homing switches
• CNC mill limit switch wiring
• CNC plasma table axis limits
• Machine retrofit projects
• Automation equipment position detection
• Robotics and motion-control projects
• Cleaner control box wiring for multi-axis systems

Compatibility Notes

• Designed for compatible CNC controller boards that support RJ45 limit switch connections.
• Confirm that your controller supports PNP NC inductive sensors before ordering.
• Inductive sensors require a metal target to trigger properly.
• Choose the cable length based on your machine size and control box location.
• This assembly is for limit/homing detection and is not a motion controller or driver.
