A capacitive proximity sensor with an adjustable detection range of 1–10 mm, capable of detecting both metallic and non-metallic objects. Unlike inductive sensors that only respond to metals, this capacitive sensor detects anything with sufficient dielectric properties — including plastics, wood, glass, liquids, and more.
Housed in a fully enclosed PBT plastic shell with IP67 waterproof and dustproof protection, it operates on a 10–30V DC supply and outputs a PNP normally-open (high-level) signal. Built-in short circuit, overload, and reverse polarity protection make it reliable for industrial and hobbyist applications alike.

Jargon buster
Plain-language definitions for the technical terms used above.
- capacitive sensing
- Capacitive sensing detects changes in electrical capacitance caused by a nearby object or material, such as a finger, water, or moisture in soil. It is used for touch buttons, proximity detection, and liquid or moisture-level sensing, and it matters because it can work without exposed metal contacts, avoiding the corrosion that bare probes suffer in damp conditions.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- IP67
- An ingress protection rating meaning the enclosure is dust-tight and can survive temporary immersion in water under specified test conditions. This matters when choosing a sensor for outdoor, wet, or wash-down environments.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- Proximity sensor
- A sensor that detects the presence of a nearby object without physical contact, using methods such as infrared, ultrasonic, capacitive, inductive or time-of-flight. Useful ranges vary widely between types, from a few millimetres to several metres, so check a given sensor's specified range to see whether it suits close-up touch-free triggers or longer-distance detection.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
