Creality Sermoon D3 Photoelectric Switch Kit 3D ZUBEHOER

Unlike generic mechanical limit switches that wear out and lose precision over time, the Creality Sermoon D3 Photoelectric Switch Kit uses a non-contact optical sensing principle to deliver repeatable, high-accuracy Z-axis homing for your Sermoon D3 3D printer. This replacement or upgrade module eliminates the physical contact and mechanical bounce associated with traditional switches, ensuring your printer consistently finds its true zero point for cleaner first layers and more reliable prints.

Highlights

• Photoelectric through-beam sensor with infrared LED for fast, wear-free detection
• Designed specifically for the Creality Sermoon D3 3D printer Z-axis
• Digital output compatible with standard 3D printer control boards
• Compact ABS housing and PCB construction for durability
• Includes connecting cable with 3-pin JST-XH connector
• High repeatability for precise homing and consistent print quality

In daily use

Installing the photoelectric switch kit restores or enhances your Sermoon D3's ability to home accurately. The slotted optical design detects the Z-axis flag without contact, so there is no mechanical wear or switch bounce. The module operates on 5V DC and provides a clean digital signal that your printer's firmware can read instantly. With a response time under 1 millisecond and a detection gap of approximately 5 mm, it ensures rapid and reliable homing even after thousands of cycles. The included 100 cm cable gives you flexibility in routing, and the screw-mount design makes installation straightforward.
