Overview
The Turck NI5-K11K-AP6X is a cylindrical inductive proximity sensor engineered for industrial automation environments where reliable, non-contact object detection is critical. Operating from 10–30VDC with a rated switching distance of 5mm, this sensor delivers repeatable, fast switching performance in tight mounting spaces. Pre-wired with a 2m cable terminated with bare end flying leads, the sensor is ready for direct integration into control circuits without additional connectors.
Key Features
- Smooth barrel design, 11mm diameter with plastic PA12-GF30 housing
- PNP output (Normally Open); supply voltage 10-30VDC nominal 12Vdc/24Vdc
- Operating current up to 200mA with no-load current ≤15mA
- IP67 protection class rated for -25…+70 °C ambient temperature
- Maximum switching frequency of 1.5kHz (1500Hz)
- Repeatability ≤2% of full scale with hysteresis 3–15%
Technical Specifications
The sensor includes built-in electrical protections and material correction factors for common industrial metals. Correction factors: St37 steel = 1.0; aluminum = 0.3; stainless steel = 0.7; mild steel = 0.4, allowing field adjustment of switching distance in multi-metal environments. Non-flush, non-threaded barrel construction simplifies mounting in tight assemblies.
Typical Applications
- Conveyor line object detection and sorting
- Part presence verification on automated assembly lines
