This compact 5V inductive proximity switch detects metal objects at distances up to 4mm without physical contact. It features an NPN normally-open output, a fast response time under 1ms, and a 1,000Hz switching frequency — making it reliable for high-speed detection applications.
With an IP67 protection rating and an operating temperature range of −20°C to 65°C, this sensor is suitable for both indoor and outdoor use. Its small 27 × 10 × 6mm form factor fits easily into tight spaces, and it comes with a 2-metre wire lead for flexible mounting.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
