1 piece SN04 series metal detection sensor for metal inspection What this is A proximity switch designed to detect metal objects without contact. Variants include SN04N, SN04N2, SN04P, and SN04P2, with NPN or PNP output options and NC or NO contact configurations. Model numbers in this family include SN04N1, SN04N2, SN04P1, SN04P2. Key benefits Noncontact metal detection reduces wear and tear on moving parts. Flexible electrical interfaces: NPN or PNP outputs to fit different control systems. Multiple contact configurations (NC and NO) to support different logic requirements. One piece per package, enabling straightforward integration into existing assemblies. Key attributes Function: metal detection using proximity sensing for automated processes. Compatibility: suitable for standard control circuits that accept NPN or PNP sensors and NC/NO outputs. Variants and models: SN04N, SN04N2, SN04P, SN04P2; model numbers SN04N1, SN04N2, SN04P1, SN04P2. Size and material: not specified in the provided information. Performance: designed for metal inspection applications within the SN04 sensor family. 23 practical use scenarios Conveyor line metal piece detection: detect metal workpieces passing on a belt and trigger a stop or divert mechanism to prevent jams or misfeeds. Assembly line inspection: verify presence or absence of metal components in a product before packaging or further processing, ensuring quality control. Machine safety interlock: monitor metal presence at guard doors or panels to ensure machinery operates only under safe conditions. Packaging and identifiers 1 piece per package Model numbers span SN04N, SN04N2, SN04P, SN04P2 and the P/N variants SN04P1, SN04P2, SN04N1, SN04N2 as applicable.
