Overview
The ifm IN5129 inductive proximity sensor provides non-contact object detection for industrial automation, motion control, and material handling applications. Operating on electromagnetic induction principles, this compact rectangular-housing sensor achieves a 4mm sensing range with non-flush mounting capability. With IP67 protection, integrated M8 connector, and 2-meter PVC cable, the IN5129 delivers robust performance in demanding manufacturing, assembly, and conveyor environments. The sensor is designed to integrate seamlessly into 24 VDC industrial control circuits and PLC input modules.
Key Features
- 4mm non-flush sensing range for precise object position and proximity detection
