Weidmüller LL 5.00/16/90 3.2SN OR BX PCB Terminal Block
The Weidmüller LL 5.00/16/90 3.2SN OR BX PCB terminal block is a robust board terminal for industrial electronics that require a higher number of connection points in one structured terminal section. In practical design work, a 16-pole PCB terminal is often selected when engineers want to consolidate wiring, reduce terminal fragmentation on the PCB, and keep installation and servicing more manageable.
Product Description
The Weidmüller LL 5.00/16/90 3.2SN OR BX is a 16-pole PCB terminal block with a 5.00 mm pitch and 90-degree conductor outlet. It includes 3.2 mm tinned solder pins, orange housing, and a clamping yoke screw connection. This format is intended for THT board integration and supports direct conductor termination on the PCB for industrial equipment.

Why 16 Poles Can Improve Board Design
The 16-pole format is useful for applications that need a broader wiring interface while still benefiting from one continuous terminal arrangement. The Weidmüller LL 5.00/16/90 3.2SN OR BX terminal block can help simplify PCB edge planning, especially in control systems and interface devices where multiple circuits must be brought together clearly.
Instead of splitting related conductors across multiple terminals, designers can create a more unified terminal strategy. This often improves assembly logic and supports cleaner documentation.
Connection and Service Benefits
The clamping yoke screw connection continues to be valued for its secure wire hold and familiar maintenance process. In many industrial environments, that familiarity is essential because service personnel need to work quickly and confidently with existing installations. The right-angle conductor outlet also supports lateral cable paths, which can reduce clutter and improve space efficiency inside the device.
Because the Weidmüller LL 5.00/16/90 3.2SN OR BX PCB terminal block supports conductors up to 6 mm², it fits a broad range of industrial board-level wiring scenarios.
Common Use Cases
Typical applications include machine controller boards, industrial communication electronics, energy management devices, HVAC control systems, and OEM automation modules. The 16-pole format is especially practical when a product needs a larger organized terminal section but still wants to keep a standard 5.00 mm pitch concept.
FAQ
What is the Weidmüller LL 5.00/16/90 3.2SN OR BX used for?
