描述

142-9303-411 is a straight cabled bulkhead SMA jack assembly designed for RG 316 cable applications in RF/microwave systems. The connector features a copper alloy body with gold plating (0.00005 inch minimum over copper plating), beryllium copper contacts with gold plating, and a TFE/LON insulator for reliable electrical performance. Key mechanical specifications include an engage/disengage torque of 2 inch-pounds maximum, mating torque of 7–10 inch-pounds, contact retention of 6 pounds minimum, and cable retention of 20 pounds minimum axial force. The assembly operates over a temperature range of -65°C to 165°C and meets MIL-PRF-39012 environmental standards including thermal shock, corrosion, shock, vibration, and moisture resistance testing. With 500 cycles minimum durability and RF performance specifications including -60 dB minimum RF leakage at 2.5 GHz and 500 VRMS minimum RF high potential withstanding voltage, this connector is suitable for demanding aerospace, military, and telecommunications applications requiring robust RF connectivity.
