Overview
The Turck BI5-G18K-AP6X-0.3M-RS4T is a compact inductive proximity sensor engineered for industrial automation and motion control. This flush-mounting M18 sensor detects ferrous and non-ferrous metal objects without physical contact, ensuring reliable and repeatable performance in harsh manufacturing environments. The sensor features a 5 mm rated switching distance and comes with a 0.3 meter pre-attached cable terminating in a male M12 x 1 connector for quick integration.
Key Features
- Flush M18 × 1 Design: Threaded barrel with chrome-plated brass housing resists corrosion and mechanical damage
- 5 mm Switching Distance: Rated detection range optimized for compact machine cavities and tight assemblies
- PNP Output: Normally open (NO) 3-wire DC logic output compatible with standard industrial controllers
- 10–30 VDC Supply: Wide operating voltage accommodates 24 VDC standard plant power and 12 VDC portable equipment
- Pre-Wired Cable: 0.3 meter pigtail with M12 connector eliminates integration delays
- Short-Circuit & Reverse Polarity Protection: Built-in safeguards extend sensor life and simplify field wiring
