Product Description
The Welker UB4N025B03GDEE1A000 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 retractable locating mechanism for controlled positioning of components in industrial automation, manufacturing fixtures, welding cells, and material handling systems.
This unit features a 25 mm stroke configuration, pneumatic operation, an orange protective steel 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 are installed on the cylinder as pictured.
The cylinder is identified as Welker UB4N025B03GDEE1A000. The manufacturer's label specifies that the mounting surface for the shot pin must be flat within 0.05 mm (0.002 in). The assembly is designed for industrial applications requiring repeatable locating and positioning of components. Please review all photos carefully for the exact ram configuration, mounting arrangement, pneumatic fittings, sensor, included components, and overall condition.
