Siemens 3RG4023-3AF01 Inductive Proximity Switch

The Pepperl+Fuchs 3RG4023-3AF01-PF Inductive Proximity Switch is a DC, three-wire sensor in an M18 cylindrical housing with an 8 mm sensing range and a normally open (NO) output configuration (PNP, 3-pin). The NO contact closes to energize the connected load when a metal target enters the sensing field, providing a sourcing output suitable for PLC inputs. As part of the 3RG4023 family, this inductive switch delivers non-contact metal detection ideal for industrial automation, including end-of-travel and position sensing on conveyors and machine tools. Common applications include inline presence checks on packaging lines, robotic cells, and other equipment where reliable metal presence sensing without physical contact is required.
