KI505A Capacitive Sensor 15mm PNP NO/NC ATEX M30 | IFM

The Original New IFM KI505A is a capacitive proximity sensor designed for non-contact detection of objects in hazardous areas, featuring a threaded M30 x 1.5 stainless steel housing. Its ATEX approval (II 3D Ex tc IIIC T90°C Dc) makes it suitable for applications in potentially explosive dust environments.The sensor features an easy-to-adjust sensing range via potentiometer, a clearly visible yellow LED switching status indicator, and a complementary PNP output function (NO/NC) for direct connection to plant control without the need for a separate switching amplifier.

Core Engineering Highlights:
15 mm non-flush sensing range (adjustable) | PNP complementary output (NO/NC) | ATEX certified for hazardous areas (II 3D Ex tc IIIC T90°C Dc) | 10-30 V DC operating voltage | 200 mA output current | 10 Hz switching frequency | IP65 / IP67 protection | –20°C to +60°C operating temperature | M30 x 1.5 threaded housing | 125 mm housing length | Screw terminal connection | 1 x yellow LED
