Gold-plated beryllium copper centre contact, PTFE dielectric — the material stack is what you expect from a production SMA that needs to hold its impedance through repeated mate cycles. Termination is solder for the centre contact and crimp for the shield — a standard combo for RG-188 cable assemblies. The kit includes four pieces: the connector body, the contact, a heat shrink sleeve, and an outer sleeve. That means you get everything needed for one termination in one order code, which saves hunting for the loose parts. 500 mating cycles is a solid figure for an SMA in field-service duty — you can reconnect it through a few equipment swaps before the gold plating starts to show wear. No successor or cross-reference part number is on record. Availability is confirmed at quote time; there is no factory lead time to rely on. If you are designing a new assembly, look for a current-production SMA for RG-188 with the same 50 Ohm impedance and threaded coupling — the pitch and interface dimensions are standardised across SMA manufacturers, so a drop-in from Amphenol or Molex is likely, but verify the cable group and centre contact style against your assembly drawing.","metaTitle":"TE Connectivity 1051655-1 SMA Plug, 50 Ohm, 12.4 GHz","metaDescription":"TE Connectivity 1051655-1 SMA plug, male pin, 50 Ohm impedance, 12.4 GHz max, for RG-188 cable.
