The Siemens 3RG4022-0AB00 is an inductive proximity switch from the 3RG4 family, with a 4 mm sensing range, PNP normally open output, and a 10-65 V DC supply range. It draws up to 300 mA and is housed in a nickel-plated brass barrel, 12 mm diameter by 62 mm long, with a 2 m cable connection. Rated IP67 for wet or dusty environments.
Non-flush mountable — the sensing face can be recessed into metal without derating the 4 mm range. The 12 mm barrel fits standard 12 mm mounting clamps or through-hole brackets. Two lock nuts are supplied for panel mounting.
