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 Key Features: Original New IFM KI505A sensor Capacitive sensing principle for non-contact detection of metallic and non-metallic objects ATEX approved for hazardous areas: II 3D Ex tc IIIC T90°C Dc 15 mm sensing range (adjustable via potentiometer) PNP complementary output function (NO/NC) for flexible integration Direct connection to plant control without switching amplifier 10-30 V DC operating voltage 200 mA permanent current rating 10 Hz switching frequency for reliable detection Clearly visible yellow LED for switching status indication IP65 and IP67 protection ratings for harsh industrial environments Non-flush (unshielded) mounting Screw terminal connection with M20 x 1.5 cable gland (0.34…1.5 mm²) Applications: Hazardous area detection in potentially explosive dust environments (ATEX Zone 22) Level detection of powders, granules, and liquids in silos and hoppers Object presence detection in food and beverage processing Position monitoring in chemical and pharmaceutical plants Conveyor and material handling systems Plastic and glass object detection Technical Specifications: Attribute Specification Catalog Number KI505A Order No. KIE4150NCPKG/3D Product Type Capacitive proximity sensor Sensing Principle Capacitive Sensing Range 15 mm (adjustable) Real Sensing Range Sr 15 mm ± 10 % Mounting Non-flush mountable Housing Threaded type, M30 x 1.5 Housing Length 125 mm Housing Material PBT; PA Electrical Design PNP Output Function Complementary (NO/NC) Operating Voltage 10-30 V DC Current Consumption < 20 mA Max.
