What is the GT5-1P-DS(A)(70)?
The Hirose GT5-1P-DS(A)(70) is a single-port coaxial receptacle with a male center pin — the body is a receptacle but the contact is a pin, not a socket. It belongs to the GT5 series and is designed for right-angle through-hole mounting to a PCB. The connector is keyed and includes a mounting flange for secure panel or board attachment, with a push-pull fastening mechanism for quick mate and unmate. Rated for 50 Ohm impedance and a maximum frequency of 2 GHz, it handles 250 V and is specified for 30 mating cycles. The center contact is brass with tin plating, and the housing is brown polybutylene terephthalate (PBT). Operating temperature range is -30°C to 105°C.
Where is this connector used?
This is an RF coaxial interconnect for board-level signal paths where a 50 Ohm controlled impedance is required up to 2 GHz. Typical applications include wireless modules, test equipment, antenna interfaces, and internal RF cabling in telecom or industrial gear where a right-angle PCB exit saves space. The keying and mounting flange prevent mis-mating and add mechanical retention in moderate-vibration environments.
What does the 30 mating cycle rating mean?
30 mating cycles is a low figure — this connector is designed for install-and-forget duty, not repeated field reconnects. The tin-plated center contact (not gold) is the limiting factor; tin wears faster under repeated insertion. If your application needs frequent cable swaps, look for a gold-plated variant in the GT5 series or a different connector family with higher cycle life.
