Description:
The Creality PCBA Limit Switch Module is a precision-engineered electronic component that serves as the "homing" sensor for your 3D printer. While the part number is frequently associated with the Y-axis (bed movement) on the Ender-3 V3 SE and KE, it is part of the newer V1.1 sensor generation that provides the control board with a definitive "zero" signal.
This module is a direct OEM replacement, featuring a pre-mounted mechanical microswitch on a specialized printed circuit board PCBA. It ensures the printer knows exactly where the mechanical limits are, preventing the motors from attempting to move the bed or toolhead beyond their physical range, which protects the machine from damage and ensures consistent print starting points.
Features:
High-Accuracy Homing: Provides reliable and repeatable detection of the axis home position, which is critical for accurate layer alignment and preventing print offsets.
Plug-and-Play Installation: Features a standard factory connector that allows for a quick "snap-in" replacement without any soldering or firmware modifications.
Stable PCB Mounting: Unlike loose microswitches, this module is mounted on a rigid PCB that ensures the switch stays perfectly aligned with the axis trigger point.
Durable Construction: Built with reinforced electrical contacts and a premium PCB substrate to withstand the repeated mechanical vibrations of high-speed printing.
Official OEM Quality: Ensures 100% compatibility with the voltage and signal logic of the Creality motherboard.
