Weidmüller BLF 5.08HC/10/90F SN BK BX Female PCB Connector Guide
The Weidmüller BLF 5.08HC/10/90F SN BK BX is a female PCB connector designed for applications where dependable field wiring, compact board integration, and service-friendly pluggable connections matter. In practical terms, this Weidmüller connector combines a 5.08 mm pitch, 10 poles, and a 90° conductor outlet direction with a PUSH IN spring connection system that supports fast and intuitive assembly. For control systems, power distribution interfaces, industrial electronics, and machine-building environments, that combination makes it a highly relevant component when engineers want repeatable wiring quality without overcomplicating maintenance.
What the Weidmüller BLF 5.08HC/10/90F SN BK BX Is Designed To Do
This Weidmüller BLF 5.08HC/10/90F SN BK BX female PCB connector belongs to the OMNIMATE Signal BL/SL 5.08 family. It is intended for field connection on printed circuit boards and uses PUSH IN with actuator technology, which helps reduce wiring time while keeping conductor handling straightforward. The product is configured as a 10-position female plug with a rated cross-section of 2.5 mm², and it is built for users who need a pluggable terminal block format that is easy to install, easy to service, and stable in demanding electrical environments.
Key Technical Features of the Weidmüller BLF 5.08HC/10/90F SN BK BX
From a specification standpoint, the Weidmüller BLF 5.08HC/10/90F SN BK BX offers IEC product data of 400 V, 24 A, and 0.2 to 2.5 mm². Under UL, it is rated at 300 V, 18.5 A, and AWG 26 to AWG 12. The connector has a maximum clamping range of 3.31 mm², a stripping length of 10 mm, 25 plugging cycles, and touch-safe protection rated IP20 when plugged and IP10 when unplugged. In dimensional terms, it measures 60.6 mm in width, 26.2 mm in depth, and 20.6 mm in height, which makes it compact enough for many densely populated board layouts while still leaving room for organized conductor routing.
Why This 10-Pole Female Plug Matters in Real Applications
A 10-pole pluggable PCB connector is often the right fit when a design needs multiple signal or low-power distribution points in one compact interface. The 5.08 mm pitch is a familiar choice in industrial electronics because it balances conductor capacity, creepage/clearance expectations, and serviceability. In day-to-day engineering work, the Weidmüller BLF 5.08HC/10/90F SN BK BX terminal block style connector can simplify cabinet wiring, support faster device replacement, and make testing or servicing easier than permanently wired alternatives.
PUSH IN Connection Benefits
One of the most useful characteristics of this Weidmüller female PCB connector is its PUSH IN with actuator design. That matters because production teams and field technicians often need a connection system that is quick but still controlled. With the BLF 5.08HC/10/90F SN BK BX, conductors can be connected efficiently, and the wide clamping range gives flexibility across common wire sizes. For projects where uptime and maintenance speed affect operational performance, that combination is valuable.
Material and Environmental Performance
The housing uses PBT insulating material in black with orange operational elements, while the contact material is a copper alloy with a tinned surface. The product is rated UL 94 V-0 and is compliant without RoHS exemption, with no SVHC above 0.1 wt% reported in the referenced data. It is also designed for operating temperatures from -50 °C to 100 °C, with installation temperatures from -30 °C to 100 °C. That profile makes the Weidmüller BLF 5.08HC/10/90F SN BK BX suitable for a wide range of industrial control and connection scenarios.
Typical Use Cases
Common use cases include control boards, interface modules, machine control assemblies, drive systems, building automation devices, and industrial power or signal distribution modules. When engineers search for terms such as Weidmüller BLF 5.08HC/10/90F SN BK BX female PCB connector, 10 pole pluggable terminal block, or Weidmüller 5.08 mm PCB connector, they are often looking for a component that supports practical wiring, long-term maintainability, and compatibility with established industrial design practices.
