D38999/20FH53PC belongs to the widely adopted MIL-DTL-38999 series wall mount circular receptacle. It’s built for rugged interconnection, commonly picked for industrial and airborne systems that demand reliable signal and power transfer under harsh field environments.
This receptacle features alloy housing with chemical nickel plating. The robust shell delivers strong EMI shielding, good resistance against shock and vibration. Its scoop-proof structure protects delicate contact pins from bending damage during angled mating, a frequent issue engineers meet in on-site wiring work. The insert layout follows standard 53 arrangement, fitted with PC type straight PCB crimp contacts. This contact design works well for direct PCB board mounting, simplifying cabinet internal wiring.
The sealing construction keeps dust and moisture out. It can operate steadily within a broad temperature range and pass strict salt spray and environmental aging tests. All mating dimensions fully comply with MIL-DTL-38999 specs, which means it can interchange with equivalent brand connectors without extra modification.
Once assembly completes, every D38999/20FH53PC unit will go through independent inspection. Our QC team checks appearance, dimensional tolerance, sealing integrity and electrical continuity one by one before packing. We keep stock for this model to support fast sample delivery. Custom adjustments on plating or contact layout can also be arranged if your project has special requirements.
