Allen-Bradley 875C-D5NN18-A2 Capacitive Proximity Switch

The Allen-Bradley 875C-D5NN18-A2 Capacitive Proximity Switch is a non-contact sensing device from Allen-Bradley designed for automation and control environments. It uses capacitive sensing to detect nearby materials without physical contact, enabling presence detection in tight spaces where physical sensors are impractical. The 875C-D5NN18-A2 designation identifies this exact sensor within Allen-Bradley’s capacitive proximity lineup and helps ensure proper integration with compatible controllers and wiring configurations. As part of the Rockwell Automation family, this switch supports standard industrial installation practices for plug-and-play integration into control panels and automated equipment.
