Overview - EN 4652-112:2015 (BNC, 50 Ω, square flange receptacle)
EN 4652-112:2015 is a CEN aerospace product standard that specifies the characteristics of a bayonet‑coupling BNC interface coaxial square flange receptacle (50 ohm) using a clamp nut assembly cable‑to‑connector technology. It defines configuration, materials, electrical and mechanical performance, environmental tests and qualification/quality assurance requirements for RF connectors intended for aerospace use.
Key topics and technical requirements
- Scope & interface: 50 Ω BNC bayonet coupling, square flange receptacle, clamp assembly cable termination.
- Dimensions & mass: Detailed maximum dimensions and mass per cable group (A and B) are given; panel thickness and flange details are specified.
- Materials & finish: Centre contact: copper alloy, gold plated over nickel undercoat; insulators: PTFE; seals: silicone rubber or silicone fluoride; body: copper alloy, nickel plated; heat‑shrink: polyolefin.
- Electrical characteristics: Impedance 50 Ω; maximum frequency up to 4 GHz; VSWR ≤ 1.15 from 1.15 GHz to 4 GHz; insertion loss 0.1·√f dB max (f in GHz); contact resistance and insulation resistance limits; withstand voltage 1 500 Veff at sea level.
- Mechanical & service requirements: Mating/unmating torque and forces, service life of 500 cycles, centre contact retention ≥ 27 N, cable retention values per cable group.
- Environmental & test methods: Extensive test program referencing EN 2591 series (visual, contact resistance, insulation, RF performance, corona, salt mist, vibration, shock, immersion at low pressure for unmated cable group A, etc.). Specific RF tests include surface transfer impedance, RF leakage (2–3 GHz), RF high potential, and impedance measurement.
- Designation, marking, packaging and storage: Identification and marking per EN 4652‑001; quality assurance and qualification per EN 9133 and EN 4652‑001.
Practical applications and who uses this standard
- Intended users: aerospace and defence manufacturers, connector designers, procurement/specification engineers, test laboratories, avionics maintenance teams and system integrators working on RF signal and telemetry interfaces.
- Typical uses: 50 Ω RF interconnects in aircraft and spacecraft avionics, telemetry, radar subsystems, ground test equipment where reliable, qualified BNC coaxial terminations with clamp nut assembly and square flange mounting are required.
- Benefits: Ensures interoperability, reproducible electrical performance (VSWR, insertion loss, impedance), environmental resilience (temperature, vibration, salt mist, low pressure) and traceable qualification for aerospace programs.
