Weidmüller BLF 5.08HC/06/90LR SN BK BX Female PCB Connector Guide
The Weidmüller BLF 5.08HC/06/90LR SN BK BX is a 6-pole female PCB connector developed for industrial field wiring on printed circuit boards. With a 5.08 mm pitch, a 90° conductor outlet direction, and PUSH IN with actuator technology, it addresses a common engineering requirement: how to create a serviceable, compact, and dependable board-level interface without sacrificing installation speed. In many practical industrial designs, six-pole connectors are an efficient middle-ground format.
Why a 6-Pole Connector Is a Useful Choice
A six-pole layout is often ideal when engineers need slightly more connection density for grouped signals, compact power distribution, or modular subsystem interfaces. The Weidmüller BLF 5.08HC/06/90LR SN BK BX provides this in a pluggable format that supports easier maintenance than fixed wiring approaches. It is therefore relevant in controller modules, machine electronics, building systems, and industrial interface boards.
Main Technical Specifications
The official product data identifies this connector with IEC ratings 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 maximum clamping range is 3.31 mm². The dimensions listed are 20.6 mm height, 29.6 mm depth, and 40.3 mm width. It uses PUSH IN with actuator wire connection technology, supports coding, and is supplied in box packaging. Like the rest of the family, it provides touch-safe protection characteristics aligned with professional PCB connection use.
Weidmüller BLF 5.08HC/06/90LR Practical Benefits in Industrial Electronics
The Weidmüller BLF 5.08HC/06/90LR SN BK BX is relevant because it helps combine installation practicality with modularity. A pluggable female PCB connector allows devices to be wired in a way that can later be disconnected and reconnected more efficiently during service. In systems where uptime is critical, even small improvements in replacement speed or troubleshooting convenience can make a meaningful difference.
PUSH IN with Actuator as a Workflow Advantage
The PUSH IN with actuator concept supports easier and faster conductor handling compared with more traditional connection approaches. For production teams, that can reduce assembly effort. For maintenance teams, it can support faster intervention with less disruption. The result is a connector that contributes to both engineering performance and operational efficiency across the product lifecycle.
Materials and Environmental Profile
The housing is based on PBT insulating material, while the contact system uses copper alloy with a tinned finish. The product is associated with UL 94 V-0 flammability behavior and is reported as RoHS compliant without exemption. These details are important because component selection in industrial electronics is often influenced by compliance, durability, and thermal expectations in addition to electrical ratings.
Typical Applications
Common applications include machine control boards, modular automation products, compact interface boards, building technology devices, and electronics assemblies where six organized terminations are required. Search phrases such as Weidmüller BLF 5.08HC/06/90LR SN BK BX female PCB connector and 6 pole pluggable terminal block connector typically align with these use cases.
