Description
Product Introduction
This ultrasonic single & double sheet detection sensor uses through‑beam ultrasonic technology to distinguish no‑sheet, single sheet and double sheet materials.
With built‑in anti‑interference chip and optional Teach‑in function, it supports reliable detection for paper, film, metal foil and complex targets including water‑covered bonded solar silicon wafers. Nickel‑plated brass housing ensures stable performance in industrial automation.
