Weidmüller BLF 5.08HC/08/90LR SN BK BX Female PCB Connector Guide
The Weidmüller BLF 5.08HC/08/90LR SN BK BX is an 8-pole female PCB connector designed for industrial field connection on printed circuit boards. This connector brings together a 5.08 mm pitch, a 90° outlet direction, and PUSH IN with actuator technology in a format that is especially useful for mid-range connection density. In practical applications, that means it can serve systems that need several organized terminations without moving into the footprint of larger multi-pole connectors.
Product Role in Industrial PCB Design
The Weidmüller BLF 5.08HC/08/90LR SN BK BX belongs to the OMNIMATE Signal BL/SL 5.08 family and is configured as a single-row female plug for field connection. Its eight-pole arrangement is a good fit for grouped control lines, compact power and signal combinations, and industrial electronics modules that need more than a minimal interface while still prioritizing serviceability. The pluggable format also supports modular design logic across the product lifecycle.
Technical Specifications
According to the official datasheet, the connector is rated at 400 V, 24 A, and 0.2 to 2.5 mm² under IEC data. Under UL, it is rated 300 V, 18.5 A, and AWG 26 to AWG 12. The maximum clamping range is 3.31 mm². The dimensions listed are 50.46 mm width, 29.6 mm depth, and 20.6 mm height. It also supports coding, provides IP20 protection when plugged, and uses a 10 mm stripping length. The rated cross-section is 2.5 mm², which supports a broad range of practical industrial conductor needs.
Why an 8-Pole Female Plug Is Valuable
Eight-pole connectors are often selected for interface boards, machine electronics, automation modules, and control systems where connection grouping matters. Using one eight-pole connector instead of several smaller units can improve organization, reduce connector count, and support cleaner maintenance procedures. The Weidmüller BLF 5.08HC/08/90LR SN BK BX addresses that requirement while preserving the familiar handling of the BLF 5.08HC family.
PUSH IN Technology and Operational Efficiency
The PUSH IN with actuator system is particularly useful in real-world workflows. During serial assembly, it can help speed up conductor insertion. During maintenance, it can make reconnection faster and more controlled. In many industrial contexts, those process improvements contribute directly to project efficiency, commissioning quality, and lifecycle service performance.
Material and Compliance Characteristics
The connector is based on PBT insulating material and copper-alloy contacts with a tinned surface. It is associated with a UL 94 V-0 flammability classification and is listed as RoHS compliant without exemption. The product data also shows no SVHC above 0.1 wt%. These are important reference points for engineers and buyers who need documentation-ready components for regulated or quality-controlled environments.
Weidmüller BLF 5.08HC/08/90LR Application Fit
Typical application areas include machine controls, modular electronics, building automation interfaces, compact industrial power and signal modules, and board-level field wiring systems that need eight organized terminations. Search queries such as Weidmüller BLF 5.08HC/08/90LR SN BK BX female PCB connector, 8 pole pluggable PCB connector, and Weidmüller 5.08 mm terminal block plug commonly align with these needs.
