132170-12-BC is an IP-68 rated SMA jack to SMA jack bulkhead adaptor designed for extreme exposure applications. It features a 50 ohm impedance with a frequency range of 0–18 GHz and a maximum VSWR of 1.30 (-17.7 dB). The adaptor is constructed with a brass body finished in black chromate over nickel, beryllium copper contacts with gold plating, and a PTFE insulator. It offers a dielectric withstanding voltage of 1000 VRMS minimum and operates over a temperature range of -65°C to +165°C. The IP68 sealing requirement ensures the adaptor can withstand 3 feet depth of water for one hour without leakage, making it ideal for harsh environmental conditions in RF and microwave applications.
