Weidmüller BLF 5.08HC/12/90F SN OR BX PCB Connector
The Weidmüller 1002190000, also known as the Weidmüller BLF 5.08HC/12/90F SN OR BX PCB connector, is part of the well-known OMNIMATE signal connector range for industrial electronics. In practical engineering terms, this product is built for control boards, interface modules, power distribution sections, and machine electronics that need a reliable pluggable connection with straightforward field wiring. Because it combines a 5.08 mm pitch with a 12-pole layout and a 90-degree female plug design, it fits applications where board space, conductor access, and serviceability all matter at the same time.
One reason engineers search for a Weidmüller BLF 5.08HC/12/90F SN OR BX female plug is the balance between compactness and usability. A 12-position connector gives enough circuits for many control and signal tasks without forcing the designer into a larger terminal architecture. On busy PCBs, that matters. The right-angle format also supports cleaner cable routing, which helps when boards are installed inside cabinets, drives, I/O assemblies, or compact industrial housings.
Technical Overview of the Weidmüller BLF 5.08HC/12/90F SN OR BX
This Weidmüller BLF 5.08HC/12/90F SN OR BX PCB plug-in connector is a female plug with PUSH IN spring connection technology and an actuator. For installers, that usually means faster conductor insertion and more controlled release during maintenance. The connector is specified for 12 poles, a 90° outlet direction, and a maximum clamping range of 3.31 mm². For many industrial users, the headline numbers are especially important: IEC 400 V / 24 A / 0.2–2.5 mm² and UL 300 V / 18.5 A / AWG 26–12. Those figures place it squarely in the category of robust PCB connectivity for industrial signal and medium-load connection tasks.
The 5.08 mm pitch remains one of the most searched and most practical formats in industrial connector design because it offers comfortable conductor spacing and dependable insulation distances for a wide range of automation products. That makes the Weidmüller BLF 5.08HC/12/90F terminal block connector a logical choice for designers who want familiar spacing, repeatable handling, and broad integration compatibility with related male headers in the same product family.
Where a 12-Pole 5.08 mm PCB Connector Makes Sense
A Weidmüller 12-pole PCB connector like this one is often relevant for PLC interface boards, relay modules, building automation control units, HVAC electronics, safety subsystems, and measurement devices. Twelve poles can cover multi-signal channels, mixed commons, sensor groups, or combined low-voltage control paths without requiring multiple smaller connectors. That simplifies both the board layout and the field wiring plan.
There is also a maintenance advantage. In service environments, pluggable connection systems are preferred because they can shorten replacement time. If a board needs inspection or exchange, a plug-and-header concept reduces the need to fully dismantle fixed wiring. In other words, the Weidmüller BLF 5.08HC/12/90F PCB connector supports not only initial assembly efficiency but also lifecycle efficiency.
Why PUSH IN Technology Matters
The PUSH IN concept is popular for good reason. It supports fast wiring, consistent conductor retention, and straightforward operation in tight installation zones. On the Weidmüller BLF 5.08HC/12/90F SN OR BX female PCB connector, the actuator further improves usability because controlled release is important during commissioning, rework, and field service. For technicians, that typically means less frustration when handling multiple terminations in a compact enclosure.
Weidmüller also positions this family around vibration resistance, durable contact behavior, and intuitive handling. Those points matter in industrial cabinets, machine-mounted electronics, and transport-related control systems where repetitive movement, long operating hours, and routine service exposure are part of normal life.
Design Considerations for Engineers
When selecting the Weidmüller BLF 5.08HC/12/90F SN OR BX 1002190000, the main design questions usually involve current loading per circuit, conductor size, routing direction, mating header compatibility, and spacing strategy on the PCB. Because this is a 90-degree female plug, it is especially useful when cable exit direction must stay parallel to the board plane. That can improve enclosure depth management and reduce wire bending stress near the connection point.
It is also wise to review whether the project needs exactly 12 poles rather than a smaller or larger count. A well-matched pole count keeps wiring organized and reduces unused positions. In clean industrial design, that kind of detail improves both documentation and field clarity.
FAQ
What is the Weidmüller BLF 5.08HC/12/90F SN OR BX used for?
It is commonly used in industrial PCB assemblies that need a pluggable field-wiring interface. Typical examples include automation controls, I/O boards, machine electronics, instrumentation modules, and building control systems. The 12-pole format is especially helpful when several signals or control lines need to be grouped into one organized connection point.
Is the Weidmüller 1002190000 a terminal block or a PCB connector?
It is best described as a pluggable PCB connector with terminal functionality. In day-to-day sourcing language, buyers may also search for it as a PCB terminal block connector, a female plug connector, or a 5.08 mm pluggable terminal connector. Those descriptions often refer to the same application category.
Why do engineers choose a 90-degree connector?
A right-angle connector helps manage wire exit direction and can save enclosure depth. It often makes cable routing neater, especially in crowded control cabinets or compact electronic housings. It can also reduce strain caused by awkward wire bends immediately above the board.
What makes PUSH IN with actuator useful?
PUSH IN technology speeds up conductor insertion, while the actuator helps with controlled release during servicing. That combination is practical when installers need repeatable wiring quality and maintenance teams need a connector that is easy to handle without wasting time.
