UPM Blade-Power Receptacle for Backplane Buses
It accepts female blade sockets and terminates via press-fit into a through-hole board — a solderless assembly method preferred in high-reliability backplanes where rework and field replacement matter. The single-row housing carries all 10 positions as power contacts, so every circuit on this connector is sized for the DC distribution rail, not signal lines. Rated at 250V with a UL94 V-0 housing and an operating temperature range of -55°C to 125°C, this receptacle is built for environments that see thermal cycling — industrial cabinets, telecom shelters, and server racks where the backplane runs warm and the connector must hold its insulation integrity.
Press-Fit Termination — Solderless Backplane Assembly
This avoids the thermal stress of wave or reflow soldering on a large multilayer board and makes individual connector replacement possible — a field-service advantage when a single power blade socket gets damaged. The through-hole mounting keeps the connector mechanically anchored to the board, and the press-fit interface is rated for the full 250V working voltage across the backplane.
10 Power Positions — All Circuits Loaded
All 10 positions are loaded with power contacts — no signal or mixed-layout option in this variant. The contact layout is listed as 10 Power, so every circuit carries the same blade geometry. For a backplane power bus, this means the connector delivers a uniform current path across the row; the board designer sizes the trace width for each position identically. The single-row arrangement keeps the footprint narrow, which helps routing density on the backplane.
Active Lifecycle and Compliance
The base product number is 120953, and the -7 suffix indicates the specific configuration — gray housing, press-fit termination, 10 positions. For compliance files, the UL94 V-0 rating and the -55°C to 125°C operating range are the key environmental specs to pass through a design review.
