Product Description

​The Panasonic SH-21E is an ultra-slim, through-beam type photoelectric sensor designed for precise object detection in industrial applications. It features side-sensing capabilities with a sensing range of up to 300 mm, making it suitable for detecting small opaque objects, such as those with a minimum diameter of 0.3 mm under optimal conditions. The sensor operates using an infrared LED with a peak emission wavelength of 880 nm and is compatible with Panasonic's SU-7 series amplifiers. It has been discontinued; for current alternatives, please consult Panasonic's official resources or authorized distributors.
