Product Description
The Welker UB4N0500A010JER1A000 is a UB4 Series pneumatic unibody shot pin designed for precision locating, positioning, and automated fixturing applications. The assembly combines a pneumatic cylinder with an integrated locating pin mechanism, providing controlled extension and retraction for use in industrial automation, manufacturing fixtures, part positioning, and material handling systems.
This unit features a 50 mm stroke configuration, pneumatic operation, an orange steel safety shroud, and an integrated Balluff BES03R3 inductive proximity sensor for position detection. The Balluff sensor operates on a 10–30 VDC supply and provides PNP switching output. Pneumatic flow-control fittings with push-to-connect connections are installed on the cylinder as pictured.
The cylinder label identifies the unit as Welker UB4N0500A010JER1A000 and specifies that the mounting surface for the shot pin must be flat within 0.05 mm (0.002 in). This assembly is designed for industrial applications requiring repeatable locating and positioning of components. Please review all photos carefully for the exact locating pin configuration, mounting arrangement, pneumatic fittings, sensor, included components, and overall condition.
