• A limit switch specially designed for use in injection molds with 3mm and 4mm rest buttons to verify that the ejector plate assembly is fully returned before allowing a mold to close after part ejection • Switch mounting is accomplished using integral mounting holes, or by using a special bracket (included) that allows the switch to slide into place from the edge of the mold base without disassembling the mold • A polyurethane dome and wire seal protect the internal switch mechanism from water or oil contamination, providing a longer switch life • Reliability for over 14 million cycles without failure • Prevents expensive mold repair and maximizes uptime • Suitable for use in environments up to 80ºC • SPST Switching action, with gold-plated internal contacts for reliable operation • Comes with wire leads (28 gauge stranded) and 2-conductor shielded cables, 2m long 65 82 6 13.5 ~42 10.5 Ø3.2
