Proximity Sensor Capacitive 4-in-1 NPN/PNP NO/NC

The PKC1820-NP is a capacitive proximity sensor designed for non-contact detection of both metallic and non-metallic targets, such as metal, oil, glass, plastic, and paper. Featuring an integrated light bar display with +/- teach-in buttons and a 4-in-1 universal output (NPN/PNP, NO/NC), it provides an adjustable 2–20 mm sensing range for parts presence and level detection. Built with IP67 environmental sealing and multi-stage circuit protection, it ensures reliable operation across 12–30VDC industrial systems.

• Broad Multi-Material Detection: Capable of detecting metals, liquids/oils, glass, plastics, and paper for level sensing and material presence.
• Teach-In Buttons & Light Bar: Features +/- teach-in buttons and an integrated light bar display for quick sensitivity calibration and visual status monitoring.
• 4-in-1 Universal Output: Combines NPN and PNP with Normally Open (NO) and Normally Closed (NC) configurations in a single 4-wire sensor.
• Adjustable 2–20 mm Sensing Range: Offers a adjustable 2 to 20 mm detection distance with a 50 Hz response frequency.
• IP67 Ingress Protection: Enclosed in a rugged, dust-tight, and waterproof body rated for operating temperatures from -20°C to +60°C.
• Electrical Protection: Equipped with surge suppression, overload protection, reverse polarity protection, and output short-circuit safeguards.
