Description
BMA Field Replaceable Connector | Slide‑On | 0.51 mm [.020 inch] | Stainless Steel Body
The ROSNOL BMA2BT50‑0020A‑M2/9X is a high‑precision BMA Jack (Female) field‑replaceable connector incorporating a 2‑hole flange mount and a 0.51 mm [.020 inch] accepts‑pin interface. It operates at 50 Ω from DC to 22 GHz with a VSWR of 1.25 or better, supported by a slide‑on coupling mechanism that ensures reliable mating. Mechanical durability includes ≥1000 mating cycles, ≥27 N center‑contact captivation, ≤13.5 N engagement force, and ≥2.0 N disengagement force.This M2 variant supports extended‑temperature operation (–65°C to +165°C) and is suitable for precision field‑replaceable high‑frequency joints, RF signal transition points in modular assemblies, and stable mechanical replacement interfaces for thermally demanding RF environments. The connector structure incorporates a stainless‑steel passivated body, gold‑plated beryllium‑copper center contact, PTFE dielectric material for stable insulation, and a silicone‑rubber gasket for environmental sealing under repeated thermal cycling.
ROSNOL’s precision‑manufactured RF connectors deliver reliable performance and represent a cost‑effective alternative to major global brands. All products are manufactured in ISO 9001‑certified facilities and comply fully with RoHS and REACH. Custom options for materials, plating, and mechanical configurations are available.
