Description

The Keyence LR-ZB250CP is a self-contained CMOS distance-based laser sensor in the LR-Z series, featuring a rectangular body with a 4-pin M8 connector. This part is also referenced under the alternate catalog number LRZB250CP. Refer to manufacturer documentation to confirm compatibility with your specific application.

The sensor detects targets at a distance of 35 to 250 mm using a red laser light source (660 nm, Class 1) and outputs a PNP open-collector signal with Light-ON / Dark-ON selectable operation. Display resolution is selectable from 1 to 3 mm, with a laser spot size of approximately 2.4 × 1.2 mm at 250 mm and response time selectable at 1.5 ms, 10 ms, or 50 ms. Power supply input is 10 to 30V DC, with power consumption of 450 mW or less.

The stainless steel housing carries IP68 (IEC60529), IP69K (DIN40050-9), and NEMA 4X/6P/13 enclosure ratings, making it suitable for washdown and harsh-environment installations. Built-in protection covers reverse power connection, output overcurrent, output surge, and reverse output connection.

About ACME MRO Solutions

We started ACME MRO Solutions to fix something we kept running into as contractors — plants down, parts slow, surplus listings you couldn't trust. Our goal is simple: get YOU the right component fast, with an honest description, so you can get back to running.

We describe what we see. Used items show signs of use; if a part has visible wear, damage, or a missing component, the condition description will say so. We don't claim anything is tested unless we tested it — and we don't bench-test parts where testing isn't practical or revealing (feed-through modules, breakers, mechanical components). When we do test something, we'll say so explicitly.

If something is our fault, we don't work through it — we make it right. We are proud to serve American manufacturing. Your uptime is our bottom line.
