Description
SMPM Jack (Female) | Soldered Cable Entry | Snap‑On | Beryllium Copper Body
The ROSNOL SMPM2E50‑EZ047A/99 is a 50 Ω SMPM jack (female) for 0.047‑inch class coax, featuring a soldered cable entry and a plug‑in center contact for low-loss, stable high-frequency interconnects up to 40 GHz. Engineered with a snap‑on coupling, it delivers VSWR ≤ 1.25 (≥ 19.08 dB return loss) from DC–26.5 GHz and ≤ 1.40 (≥ 15.56 dB) from 26.5–40 GHz, with insertion loss specified as ≤ 0.04 × √f(GHz) dB. Mechanical performance includes center‑contact captivation ≥ 7 N, typical smooth‑bore engagement ≤ 11 N, full‑detent engagement ≤ 19 N, and minimum disengagement forces of 11 N (smooth bore) and 29 N (full detent). The connector is rated at 325 V rms, with insulation resistance ≥ 5 GΩ and low contact resistance (≤ 6.0 mΩ center, ≤ 2.0 mΩ outer).
The ROSNOL SMPM2E50‑EZ047A/99 uses non‑magnetic, gold‑plated beryllium copper for both body and center contact, with a PTFE dielectric. This solder‑terminated design is suitable for RSR047, RSF047, RSF047‑FEP, RSF047‑PVC, and EF047 cables.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and are fully RoHS and REACH compliant. Customization services for plating, materials, and mechanical design are available upon request.
