Siemens 3RG4012-3AG01 Inductive Proximity Switch

Siemens 3RG4012-3AG01 SIMATIC PXI Inductive Proximity Switch is a compact metal-sensing device that detects nearby metal targets at a 2 mm range, making it ideal for precise position sensing in PXI automation systems. This three-wire, M12-connector sensor features a PNP normally open output and operates from 10 to 34 V DC, drawing up to about 200 mA under load. Its nickel-plated brass body provides robust durability, and with an IP67 enclosure rating it withstands dust, water, and washdown environments typical of manufacturing floors. The 3RG4012-3AG01 is designed for rapid integration with SIMATIC PXI modules, enabling straightforward digital signaling for end-of-travel, presence checks, or alignment verification on conveyors and automated machinery. Common applications include machine automation, packaging lines, and robotic cells where tight sensing proximity and reliable metal detection are required. With its 2 mm sensing distance, M12 3-wire connection, and rugged construction, this proximity switch delivers repeatable sensing performance while maintaining a compact footprint for panel- or rail-mounted installations.
