Product details
Switchcraft Inc.'s RA49B12A represents a breakthrough in Barrel - Audio Connectors technology for aerospace applications. This MIL-DTL-38999 compliant connector delivers mission-critical reliability in avionics systems, satellite communications, and flight control interfaces while withstanding extreme vibration and thermal cycling.The Phone Jack implementation features triple-start threads for rapid mating. Compared to commercial variants, its bayonet coupling achieves 100N retention force in high-vibration environments.Female options include hermaphroditic designs for reduced part numbers. The self-aligning guide pins enable blind mating in zero-gravity conditions.Supporting Mono topology, the connector handles ARINC 429 avionics protocols. The impedance-controlled layout maintains signal integrity at 100Mbps data rates.Compliant with 6.35mm (0.250", 1/4") - Headphone specifications, the connector interfaces with MIL-STD-1553B databus systems. The anti-FOD design prevents foreign object debris in flight systems.The 0.253" (6.43mm) dimensions incorporate EMI/RFI shielding. The aluminum alloy shell provides 85dB shielding effectiveness while minimizing weight.2 Conductors, 3 Contacts arrangement supports quad-redundant signaling. The cross-contact design maintains connectivity during single-point failures.The Single Switch configuration includes built-in test capabilities. The embedded sensors monitor contact resistance in real-time.Designed for Through Hole, Right Angle installation, the connector features explosive decompression protection. The vented design prevents pressure differential damage at 50,000ft altitudes.Solder process utilizes crimp-and-pott technology. The environmentally sealed contacts survive 1000+ thermal shock cycles.With Unshielded effectiveness of 120dB, the connector meets DO-160G lightning protection requirements. The composite shell provides EMP hardening.The Board Guide package includes corrosion-resistant beryllium copper contacts. The precious metal plating withstands 500+ mating cycles in salt fog environments.
