The IFM KD001A is a long-range capacitive sensor designed for industrial and hazardous-area applications. It provides a 60 mm adjustable sensing range with selectable normally open and normally closed operation. The sensor operates from 20 to 250 V AC/DC and uses a combined AC/DC output stage. Its ATEX-certified construction is suitable for specified explosive dust environments. The rectangular 105 × 80 × 42 mm housing provides a robust non-flush installation format.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The KD001A provides a 60 mm sensing range for non-contact material detection. Its sensing range can be adjusted using the integrated potentiometer. The real sensing range is 60 ±10%, with correction factors for glass, water, ceramics and PVC. Hysteresis is 1 to 15% of Sr. The operating temperature is -20 to 60°C for this hazardous-area version.
The KD001A carries the ATEX marking II 3D Ex tc IIIC T90°C Dc X IP65. This certification is specifically relevant to designated combustible-dust environments when the installation requirements are satisfied. The sensor uses protection class II electrical construction. A fast-acting miniature fuse up to 2 A is specified, with the fuse located outside the hazardous area. This makes correct installation and protection essential.
The sensor uses a rectangular PPE-modified and PA housing measuring 105 × 80 × 42 mm. It is designed for non-flush mounting and weighs approximately 281.5 g. A yellow LED provides switching-status indication. Terminal wiring accepts 0.34 to 2.5 mm² conductors. The cable gland specification is M20 × 1.5.

The ATEX marking makes the KD001A suitable for specified hazardous dust applications. The installation must follow the applicable hazardous-area requirements. The fast-acting fuse must be located outside the hazardous area as specified. The 60 mm sensing range provides useful detection distance for larger process equipment. The robust rectangular housing supports stable machine installation.
The sensing range can be adjusted using the integrated potentiometer. This allows the switching point to be matched to the actual target position. The yellow LED provides visual confirmation of switching status. Terminal wiring supports a broad range of conductor sizes. Correct grounding, protection and hazardous-area installation procedures remain essential.
