Weidmüller 1000040001 BLF 5.08HC/03/90 SN BK BX PCB Plug-in Connector Guide
The Weidmüller 1000040001 BLF 5.08HC/03/90 SN BK BX PCB plug-in connector is a compact connection component designed for dependable wire-to-board interfaces in industrial electronics. When engineers search for a 5.08 mm PCB connector, a 3-pole pluggable terminal block, or a right-angle female plug connector, this model often stands out because it combines practical installation geometry with a modern PUSH IN spring connection concept.
At a product architecture level, the Weidmüller BLF 5.08HC/03/90 SN BK BX is built for applications where space, serviceability, and electrical stability all matter. The 3-pole format makes it a logical choice for compact control boards, signal interfaces, small power distribution points, and modular device connections where only a limited number of conductors are needed but secure retention remains essential.
What the Product Is and Why It Matters
This Weidmüller 1000040001 connector belongs to the BLF 5.08HC family, a range known for 5.08 mm pitch connectivity and a 90-degree wire entry format. In practical terms, this means the connector supports organized cable routing on PCBs where vertical clearance and enclosure space need to be managed carefully. The right-angle design can make assembly cleaner in compact housings and can help reduce unnecessary cable bending stress.
The “HC” designation is especially relevant in technical evaluation because it points to a high-current capable design within this series. For engineers comparing a Weidmüller 3-pole PCB plug-in connector against generic alternatives, this matters because connector selection is not just about fit. It is also about current handling, voltage capability, conductor range, long-term reliability, and ease of maintenance during field service.
Key Technical Characteristics
The Weidmüller 1000040001 BLF 5.08HC/03/90 SN BK BX female plug uses a 5.08 mm pitch and a 3-position layout. It is a black plug-in connector with PUSH IN spring connection technology and actuator-assisted conductor handling. That combination is valuable in control cabinet manufacturing, machine building, interface electronics, and PCB-based industrial devices because it supports faster, more repeatable wiring compared with traditional screw-based approaches.
In day-to-day engineering work, the most important benefit of this product is consistency. A connector like this is expected to hold conductors securely, simplify repeated maintenance access, and support efficient pre-assembly workflows. The 3-pole configuration is also a smart fit for low-channel-count connections such as line-neutral-earth arrangements, basic sensor wiring, compact actuator interfaces, or separated low-voltage board connections.
Where a 3-Pole PCB Plug-in Connector Fits Best
The Weidmüller BLF 5.08HC/03/90 SN BK BX PCB plug-in connector is especially relevant where a board needs a removable field connection rather than a permanent soldered cable. In industrial environments, this simplifies commissioning and replacement. If a device must be swapped, the wiring process can be more structured because the connector concept supports modular handling.
It can be used in compact controllers, interface cards, compact power electronics, building automation modules, and measurement devices. Because it is a right-angle pluggable terminal block, it suits layouts where cable exit direction must stay aligned with enclosure boundaries. This helps maintain a neat internal build and can improve service access.

Weidmüller 1000040001 Why Engineers Choose PUSH IN Connection Technology
One reason the Weidmüller 1000040001 PCB connector attracts attention is the PUSH IN spring system. In modern panel and device production, engineers increasingly value connection solutions that shorten assembly time without compromising contact integrity. PUSH IN designs support direct conductor insertion for suitable wire types and provide a structured method for conductor release when servicing is required.
This is particularly important in serial manufacturing environments where consistency is a strategic advantage. Faster wiring, less dependence on torque tools, and a cleaner installation routine can support both production efficiency and quality assurance.
Weidmüller 1000040001 FAQ
What is the main use of the Weidmüller 1000040001 BLF 5.08HC/03/90 SN BK BX?
Its main use is to create a removable wire-to-board connection on industrial PCBs. The 3-pole format is ideal for compact circuits that need reliable field wiring with straightforward installation and maintenance access.
Is this a screw-type connector?
No. This model uses PUSH IN spring connection technology with actuator support. That makes it different from classic screw terminal solutions and attractive for applications where installation speed and repeatability are important.
Why does the 90-degree design matter?
The 90-degree wire entry helps manage space inside enclosures and supports organized cable routing. This is particularly useful in devices where vertical height is limited or where side-entry wiring improves service accessibility.
Who should choose a 3-pole version instead of a higher-pole model?
A 3-pole version is generally the right choice when the circuit only requires a small number of conductors. It supports compact design, avoids unused positions, and can help keep the PCB interface aligned with the actual wiring architecture.
Is the Weidmüller 1000040001 suitable for industrial electronics?
Yes. The product family is widely associated with industrial PCB connectivity, especially in control technology, interface design, machine building, and modular electronic assemblies where dependable plug-in wiring is required.
