Scope
Main technical content: This document specifies the terms and definitions, classification, characteristics, and normal operating conditions of inductive proximity switches, as well as basic requirements, technical specifications, test methods, inspection rules, marking, packaging, transportation, and storage, and quality commitments. This document applies to inductive cylindrical thread-type proximity switches (hereinafter referred to as proximity switches) that operate by sensing metal objects. The proximity switch is equipped with a semiconductor switching element and can be used to connect circuits with a rated voltage of no more than 250 V AC (50 Hz or 60 Hz) or no more than 300 V DC.
