Weidmüller BLF 5.08HC/05/90LR SN BK BX Female PCB Connector Guide
The Weidmüller BLF 5.08HC/05/90LR SN BK BX is a 5-pole female PCB connector designed for professional board-level field wiring in industrial environments. It combines a practical pole count with a 5.08 mm pitch and a 90° conductor outlet direction, making it suitable for control electronics, modular interfaces, and compact industrial devices. Because it belongs to the BLF 5.08HC family, it also benefits from the established logic of pluggable connectivity and PUSH IN termination convenience.
Where a 5-Pole Connector Fits in Real Designs
Five-pole connectors are often used where a circuit needs a slightly broader interface than the most common 2-, 3-, or 4-pole formats. That may include grouped control signals, power plus signal combinations, or dedicated device interfaces in machinery and automation. The Weidmüller BLF 5.08HC/05/90LR SN BK BX supports these needs without forcing the designer into a physically larger connector than necessary.
Technical Data at a Glance
The official Weidmüller data lists this connector with IEC values of 400 V, 24 A, and 0.2 to 2.5 mm². Under UL, it is rated 300 V, 18.5 A, and AWG 26 to AWG 12. It has a maximum clamping range of 3.31 mm² and is supplied in box packaging. The housing dimensions are 20.6 mm high, 29.6 mm deep, and the 5-pole body width is 35.22 mm. As with the other family members, it offers IP20 protection when plugged and uses PUSH IN with actuator technology for the wire connection.
Why the Weidmüller BLF 5.08HC/05/90LR SN BK BX Stands Out
The strength of this connector lies in how well it matches common industrial expectations. It is compact enough for efficient PCB use, but still supports a solid 2.5 mm² rated cross-section and practical conductor handling. Because it is a female pluggable connector, it can also support modular device architecture and reduce servicing complexity. In fast-moving industrial operations, that kind of time-saving advantage often matters more than it initially appears.
PUSH IN Benefits for Assembly and Service
The PUSH IN with actuator method is an especially relevant benefit in this series. It supports quick conductor insertion and clear release handling, helping technicians complete wiring tasks with less effort. This can improve assembly consistency during production and make service work more efficient during maintenance windows. For integrators and panel builders, those workflow gains help strengthen the overall value proposition of the connector.
Weidmüller BLF 5.08HC/05/90LR Material and Compliance Considerations
The Weidmüller BLF 5.08HC/05/90LR SN BK BX uses PBT insulating material, a tinned copper-alloy contact system, and a black housing with orange actuation elements. The flammability class is UL 94 V-0, and the product is listed as RoHS compliant without exemption. The family is also designed for demanding industrial temperature ranges, supporting applications where environmental resilience is part of the purchasing decision.
Use Cases and Search Relevance
Typical application areas include controller boards, compact industrial devices, automation interfaces, machine electronics, and building control modules. Users often search for terms such as Weidmüller BLF 5.08HC/05/90LR SN BK BX female PCB connector, 5 pole PCB terminal block connector, or Weidmüller 5.08 mm female plug when specifying components for these kinds of systems.

Weidmüller BLF 5.08HC/05/90LR FAQ
What is this connector mainly used for?
It is mainly used for pluggable field wiring on PCBs in industrial and electronic equipment where five organized terminations are needed.
Does the 5-pole format offer practical advantages?
Yes. It provides more flexibility than smaller pole counts while staying compact enough for many board layouts and modular interfaces.
What conductor range does it support?
It supports 0.2 to 2.5 mm² conductors under IEC data and AWG 26 to AWG 12 under UL data.
Why is PUSH IN technology useful?
PUSH IN technology can reduce wiring time, support more consistent terminations, and improve handling during both assembly and service work.
Is it suitable for compliance-conscious projects?
Yes. The datasheet indicates RoHS compliance without exemption, which is useful for projects with documented material and regulatory requirements.
