The Siemens 3RG4112-3AG01 is a proximity switch designed for reliable industrial sensing applications. This sensor features a straight, shielded M12 housing with a 12 mm sensing range, making it suitable for detecting metal objects in tight or confined spaces. Operating within a voltage range of 6 to 30 VDC and supporting up to 500 mA, it provides a normally open NPN output with a 4-pin connection. This proximity switch is well-regarded for its durability and precise performance, and it is available through BSP Automation for your automation and control projects.
