The KI001A is an ATEX-certified AC/DC capacitive sensor designed for hazardous dust environments. It provides a 15 mm adjustable sensing range with selectable normally open or normally closed output. The sensor operates from 30–250 V AC and 20–250 V DC. Its M30 × 1.5 threaded housing has a 125 mm length and IP65/IP67 protection. Terminal connection, a yellow status LED, and hazardous-area certification support specialized industrial installations.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The KI001A provides a 15 mm sensing range. The sensing distance is adjustable with a 15 mm factory setting. The real sensing range is 15 ±10%. Correction factors are specified for common materials. This provides flexible detection for solids and liquids.
The sensor carries Ex II 3D Ex tc IIIC T90°C Dc marking. It is certified under BVS 20 ATEX E058 X and IECEx BVS 20.0061X. This makes it suitable for specified hazardous dust environments. The operating temperature is -20 to 60°C. IP65/IP67 protection supports industrial enclosure requirements.
The sensor accepts 30–250 V AC and 20–250 V DC. Its output can be selected between NO and NC. Continuous AC/DC current is 100 mA, increasing to 150 mA up to 40°C. The short-time current rating is 1000 mA. Switching frequency is 10 Hz for AC and DC.
