Weidmüller BLF 5.08HC/12/90F SN BK BX Female PCB Connector Guide
The Weidmüller BLF 5.08HC/12/90F SN BK BX is a 12-pole female PCB connector developed for industrial electronics, control interfaces, and modular device wiring where pluggable connectivity is a clear operational advantage. As part of the OMNIMATE Signal range, it combines a 5.08 mm pitch with a 90° outlet direction and PUSH IN connection technology. That mix gives designers a practical route to faster wiring, easier servicing, and cleaner PCB integration in applications where reliability and layout efficiency both matter.
Understanding the Product Format
This Weidmüller BLF 5.08HC/12/90F SN BK BX female plug is designed for field connection on PCBs. It uses a single-row, 12-position format and supports coding, which is useful when systems need mechanical differentiation to reduce mismating risk. Because it is a pluggable terminal block style connector, it supports modular assembly concepts and helps reduce downtime during servicing. In many industrial projects, that can be just as important as the pure electrical rating.
Technical Specifications That Matter
The connector is specified at 400 V and 24 A according to IEC product data, with a conductor range of 0.2 to 2.5 mm². Under UL data, it is rated 300 V, 18.5 A, and AWG 26 to AWG 12. It features a maximum clamping range of 3.31 mm², 25 plugging cycles, and a 10 mm stripping length. The body dimensions are 70.76 mm wide, 26.2 mm deep, and 20.6 mm high. It also offers IP20 touch protection in the plugged state and IP10 when unplugged, making it relevant for controlled industrial installation environments.
Why Engineers Use a 12-Pole 5.08 mm PCB Connector
A 12-pole connector is a useful choice in systems that need more connection density than smaller plugs can provide, while still avoiding the complexity of larger multi-board interfaces. The 5.08 mm pitch is widely recognized in industrial design because it supports practical conductor handling and dependable board-level spacing. In real projects, a connector like the Weidmüller BLF 5.08HC/12/90F SN BK BX can help simplify interface boards, controller terminals, and machine subassemblies.
Advantages of the PUSH IN Design
The PUSH IN with actuator concept is one of the strongest functional advantages of this Weidmüller female PCB connector. It helps teams work faster during assembly and can make service interventions more efficient in the field. For organizations that prioritize repeatable workmanship and reduced installation time, that connection method supports a strong process outcome. It also fits well with industrial environments where a connector needs to be straightforward for both production technicians and maintenance personnel.
Material Quality and Operating Environment
The product uses PBT insulating material with black housing and orange operational elements. The contact system is based on a copper alloy with a tinned surface, and the flammability class is UL 94 V-0. According to the datasheet, the operating temperature range extends from -50 °C to 100 °C, while installation is specified from -30 °C to 100 °C. The connector is RoHS compliant without exemption and reports no SVHC above 0.1 wt%, which is relevant for projects with compliance-driven procurement requirements.
Where the Weidmüller BLF 5.08HC/12/90F SN BK BX Fits Best
This connector fits well in industrial control boards, automation modules, interface electronics, power distribution boards, building automation devices, and machine control systems. Searches for terms like Weidmüller BLF 5.08HC/12/90F SN BK BX female PCB connector, 12 pole pluggable PCB terminal block, or Weidmüller 5.08 mm female plug often reflect the need for a component that balances wiring speed, electrical robustness, and serviceability.
