Siemens 3RG4041-6KD00 129258 SIMATIC PXI340 Proximity Switch Sensor Inductive

1. Overview of the Siemens 3RG4041-6KD00 129258

The Siemens 3RG4041-6KD00 is an inductive proximity switch. Its flat, 40 × 40 mm ABS housing fits comfortably in the palm of your hand, yet it accurately detects any metallic target within a 20 mm sensing distance. Its two-wire design reduces wiring from three to two conductors, saving 30% on-site installation time. Utilizing a dedicated ASIC, it offers a wide-range 15–34 V DC power supply and 0.2 A output current, enabling direct driving of small relays and seamless integration into PLC input modules, enabling true "plug-and-measure" functionality.
