Weidmüller BLF 5.08HC/03/90 SN OR BX SO Conector macho PCB, 3 polos, paso 5,08mm, 90° Push-In, naranja 2764380000

In automated assembly lines and industrial control cabinets, technicians rely on the Weidmüller BLF 5.08HC/03/90 SN OR BX SO to establish dependable wire-to-board connections without tools. This 3-pole PCB plug-in connector features a 5.08 mm pitch and a 90° wire entry, making it ideal for tight spaces where horizontal access is required. The PUSH IN connection technology allows solid or flexible conductors with ferrules to be inserted directly, reducing wiring time and ensuring a secure, vibration-resistant contact. The orange PBT housing provides clear visual identification and meets UL 94 V-0 flammability standards, while the tin-plated copper alloy contacts deliver reliable conductivity. With a rated voltage of 400 V and current of 17.5 A per IEC, this connector is suited for power and signal distribution in demanding industrial environments. The operating temperature range of -50 °C to 100 °C ensures performance in harsh conditions, from cold storage to high-heat machinery. Each pole accommodates wire sizes from 0.2 to 2.5 mm² (AWG 24–12), and the 10 mm stripping length simplifies preparation. The connector is part of the OMNIMATE BLF series, known for its robustness and compatibility with standard 5.08 mm headers. Whether you are building control panels, motor drives, or sensor interfaces, this plug-in connector offers a maintenance-free and space-efficient solution.

Why choose it

The PUSH IN connection eliminates the need for screwdrivers or crimping tools, cutting installation time by up to 50% compared to screw terminals. The 90° orientation allows cables to exit parallel to the PCB, saving vertical space in dense enclosures. The high current rating of 17.5 A and 400 V voltage rating make it suitable for power circuits, while the wide temperature range ensures reliability in extreme conditions. The orange housing is not just aesthetic—it aids in quick identification during maintenance and reduces wiring errors. The tin-plated contacts provide excellent corrosion resistance and low contact resistance over the product's lifetime. As part of the Weidmüller OMNIMATE BLF series, this connector is engineered for high mating cycles and long-term stability in industrial automation.

Ideal use cases

• Industrial control panels and PLC I/O modules
• Motor drives and frequency inverters
• Sensor and actuator wiring in machinery
• Power distribution boards
• Building automation systems
• Test and measurement equipment

Good to know

The connector is designed for use with standard 5.08 mm pitch headers, such as Weidmüller SL 5.08 series. For flexible wires without ferrules, it is recommended to use ferrules to ensure proper PUSH IN connection. The PBT housing is resistant to many industrial chemicals and oils. The product is RoHS compliant and meets relevant IEC and UL standards. Always verify the maximum operating voltage and current for your specific application and consider derating at elevated temperatures. The connector is supplied as a single piece, and multiple connectors can be used side by side without loss of pitch.
