Overview
The Turck BI1-EG05-AP6X-V1331 inductive proximity sensor is a compact, high-performance device designed for precise, contactless metal detection in industrial automation and machine control applications. With 1mm rated switching distance and robust stainless steel construction, this sensor offers reliable performance in harsh environments where corrosion resistance and durability are essential.
Key Features
- 1mm Sensing Range — Precise, short-distance metal detection for tight mounting spaces and compact machine designs
- PNP Output — NO contact configuration with 3-wire DC circuit; easily interfaces with standard industrial controllers and PLCs
- Stainless Steel Housing — IP67-rated AISI 303 (1.4305) construction resists corrosion in washdown, wet, and chemical-rich environments
- M5 × 0.5 Flush Threaded Barrel — Embeddable design allows flush mounting in machine frames and panels with minimal protrusion
- 3 kHz Switching Frequency — Rapid response suitable for high-speed production lines and motion control systems
- Yellow LED Status Indicator — Visual feedback for switching state simplifies troubleshooting and commissioning
