Overview
The Turck BI4-Q06-AP6X2-0.8-PSG3M/S1174 inductive proximity sensor is a fully-sealed, flush-mount unit designed for rapid, contact-free metal detection in compact mounting envelopes. Operating across 10–30VDC with a 4mm rated switching distance and ≤200mA output, this sensor combines reliability with cost-effectiveness for applications in automotive assembly, packaging machinery, material handling, and general manufacturing automation.
Key Features
- 4mm Flush-Mount Sensing: Rated switching distance of 4mm enables detection in confined spaces and tight fixture designs.
- Wide Supply Range: 10–30VDC operation ensures compatibility with 12V, 24V, and higher industrial control systems.
- Low Operating Current: Draws ≤15mA in no-load state, reducing control circuit power demands.
- Short-Circuit Protected: Integrated cyclic short-circuit protection safeguards against accidental wiring faults.
- Compact Geometry: 5.5mm housing height facilitates integration into space-constrained assemblies.
- Repeat Accuracy: ±2% of full scale ensures consistent switching performance over millions of cycles.
