Capacitive Sensor Threaded Type Model KI503A 1030 V DC PNP Product overview A compact capacitive proximity sensor in a threaded housing, model KI503A, designed for reliable noncontact detection of solids and liquids. Operates from 10 to 30 V DC and uses a PNP switching output for straightforward integration with PNP input controllers. Key benefits Reliable noncontact detection: Detects changes in dielectric properties to sense plastics, liquids, powders, and other materials without physical contact. Easy installation: Threaded form factor allows secure mounting and simple height adjustment for precise detection distances. Simple integration: PNP output and 10 to 30 V DC supply voltage make it compatible with common PLCs, controllers, and automation equipment that use sourcing inputs. Compact and versatile: Suitable for tight spaces and a variety of industrial applications where compact sensors are required. condition: Supplied as a unit to ensure full operational life and consistent performance. What makes it stand out Capacitive sensing allows detection of both conductive and nonconductive materials, offering greater flexibility than standard inductive sensors. Threaded housing provides a stable mechanical mounting option for repeatable sensing positions. Broad supply voltage range supports varied industrial power systems and reduces need for additional power conditioning. Functional highlights Sensing method: Capacitive proximity sensing for solids and liquids. Output type: PNP switching output for sourcing control circuits. Supply voltage: 10 to 30 V DC. Mounting: Threaded type for secure, adjustable installation. Condition: unit ready for deployment. Practical use scenarios Level detection in small tanks or hoppers: Detect liquid level changes or material presence through nonmetallic walls or directly at the sensing point to automate refilling or alarms. Presence detection on packaging lines: Sense plastic or cardboard packages and activate conveyors, gates, or counting systems without contact wear. Position sensing in assembly machinery: Monitor the presence of plastic parts, foam inserts, or nonmetallic components to confirm correct placement before the next process step. Compatibility and integration Designed for integration with systems that accept PNP sensor inputs and a 10 to 30 V DC supply. Threaded form factor fits common mounting brackets and sensors clamps for industrial automation setups. Suitable for use in conjunction with PLCs, discrete controllers, and relay logic requiring sourcingtype signals. Why choose this sensor Practical for mixedmaterial detection tasks where both conductive and nonconductive items must be sensed. Threaded housing and standard supply/output characteristics simplify retrofits and installations. condition ensures predictable behavior and minimal downtime after installation.
