The nickel-plated brass body and gold center contact give a corrosion-resistant signal path that holds up to 500 mating cycles before the gold starts to wear through. ## Cable prep and crimp termination This plug terminates with a standard crimp sequence: strip the coax to the dimensions in the Molex drawing, slide the ferrule over the jacket, crimp the center contact onto the conductor, then push the contact into the dielectric body until it seats, and finish by crimping the ferrule over the braid. The snap-on fastening type gives a positive lock with no tools — push to mate, pull to release. The 335 V voltage rating is generous for the cable types it's specced for; the practical limit is the cable's own breakdown voltage, not the connector's.","metaTitle":"Molex 0734040710 SMB Plug, 50 Ohm, 4 GHz, RG-174/188/316","metaDescription":"Molex 0734040710 SMB plug, female socket, 50 Ohm, 4 GHz max, crimp termination for RG-174/188/316 cable.
