Ruland Disc, 50.8mm Outside Diameter, 20mm Bore, 64mm Length Flexible Coupling

VAL-U-LOK right angle and vertical double row PCB mount pin headers with a 4.2mm centerline and tin plated brass male pin contacts. These VAL-U-LOK pin headers have an easy mate and unmate design with positve latching and have keying to ensure accurate alignment when mating. In addition these VAL-U-LOK pin header connectors are available with pegs (or boardlocks) for alignment on the PCB. The housings of these VAL-U-LOK pin headers are made from UL94V-0 or UL94V-2 rated natural nylon.
