Weidmüller LL 5.08/04/90 3.2SN OR BX PCB Terminal Block
The Weidmüller LL 5.08/04/90 3.2SN OR BX PCB terminal block is a compact board-level terminal for industrial electronics that require dependable conductor termination in a smaller pole-count format. Despite its modest 4-pole configuration, the product is highly relevant to many control and interface tasks where clean PCB integration, robust wire handling, and a familiar screw-based connection remain essential.
Product Overview
The Weidmüller LL 5.08/04/90 3.2SN OR BX is a printed circuit board terminal block with a 5.08 mm pitch, 4 poles, 90-degree conductor outlet direction, 3.2 mm solder pin length, tinned finish, and orange housing. It uses a clamping yoke screw connection and is supplied in box packaging. This makes it suitable for PCB designs where direct field wiring is required without overcomplicating the connection architecture.
Because it is a Weidmüller LL 5.08/04/90 3.2SN OR BX PCB terminal block, it matches search intent around a 4-pole PCB terminal block, a 5.08 mm board terminal, or a right-angle Weidmüller PCB terminal for industrial devices.

Why the 4-Pole Format Is So Useful
A 4-pole terminal block is often the right choice for compact applications such as power input points, small controller interfaces, sensor or actuator connections, and simple low-voltage distribution tasks on a PCB. The Weidmüller LL 5.08/04/90 3.2SN OR BX terminal block is particularly useful when designers want a durable board terminal rather than a lighter-duty plug solution.
The 5.08 mm pitch offers slightly increased spacing compared with a 5.00 mm version, which can be attractive in applications where designers prefer a familiar industry-standard step size and slightly broader spacing concept.
Connection and Mechanical Benefits
The clamping yoke screw connection gives the Weidmüller LL 5.08/04/90 3.2SN OR BX PCB terminal block a secure and proven conductor retention method. This remains highly relevant in industrial environments where connectors and terminals are expected to stay reliable over long operating periods and across maintenance cycles.
The 90-degree design supports side-entry cable routing, making it easier to integrate into low-profile housings. This can help improve cable organization and reduce mechanical stress on conductors after installation.
Typical Applications
This terminal block can be used in compact industrial control boards, power input stages, signal conditioning modules, building control electronics, safety interfaces, and OEM devices where only a few direct PCB terminations are needed. Its conductor range makes it flexible enough for a wider variety of tasks than many smaller signal-only terminal concepts.
Because it comes from the broader Weidmüller PCB terminal ecosystem, it can also support design consistency when other related terminals are used on adjacent assemblies.
FAQ
What is the Weidmüller LL 5.08/04/90 3.2SN OR BX used for?
It is used for direct conductor termination on printed circuit boards in compact industrial and electronic applications with four connection points.
Why choose a 4-pole PCB terminal block?
A 4-pole version is a good fit for compact power, signal, or interface tasks where only a few conductors need to be terminated securely.
What is the benefit of 5.08 mm pitch?
It is a familiar industrial pitch that offers practical spacing for conductor handling and electrical design.
Is the screw connection still advantageous?
Yes. It remains a dependable and widely accepted solution for industrial board terminals because it is secure and easy to service.
Can this product support larger conductors than a typical signal terminal?
