Weidmüller 1002040000 PCB Terminal Block: Technical Explanation and FAQ
The Weidmüller 1002040000 PCB terminal block, full type Weidmüller LL 5.08/23/90 3.2SN OR BX PCB terminal block, is a 23-pole board terminal developed for industrial wire-to-board connectivity. In practical terms, it is intended for engineers who need a high connection count, robust clamping performance, and a board-mounted interface that remains easy to service after installation.
It belongs to the OMNIMATE Signal LL series and follows a proven design concept: 5.08 mm pitch, 90° conductor outlet direction, through-hole solder mounting, and a clamping yoke screw connection. With these features, the part supports industrial assembly workflows while fitting well into compact and medium-scale control electronics.
Technical Details of the Weidmüller 1002040000
The Weidmüller 1002040000 printed circuit board terminal has 23 poles and a maximum clamping range of 6 mm². It uses a 3.2 mm tinned solder pin, an orange housing, and box packaging. Published series data lists IEC 500 V / 32.5 A with 0.5 to 6 mm² conductor support, and UL 300 V / 20 A with support for AWG 26 to AWG 12.
At this pole count, a PCB terminal block becomes especially useful where one board must present a substantial number of field terminations in a single continuous interface. That can improve labeling clarity and reduce the need for multiple separate terminal zones.
Why 23 Poles Can Improve Board Organization
A 23-pole PCB terminal block is not a generic low-count connector; it is a structured termination solution for more complex board architectures. Designers working on industrial controllers, process electronics, building technology boards, or equipment interfaces often reach this pole range when trying to keep the connection layout centralized and logical.
The Weidmüller 1002040000 wire-to-board terminal block is also helpful for maintaining predictable cable routing. Because the wires exit at 90°, the installed conductors can be organized neatly alongside the PCB plane. In cabinets and devices with limited vertical height, that can make a noticeable difference.
Typical Applications for the Weidmüller 1002040000
This model is suitable for machine controller boards, interface electronics, power and signal distribution PCBs, monitoring systems, and custom industrial devices. It is particularly relevant in applications where maintenance technicians benefit from clearly arranged, screw-terminated wiring on the board edge.
Common search patterns in technical sourcing include Weidmüller 1002040000 PCB terminal block, Weidmüller 1002040000 terminal block, 23 pole PCB terminal block, and 5.08 mm Weidmüller PCB terminal. These queries show how exact-fit selection often depends on both the order code and the functional terminal format.
Design and Maintenance Considerations
When using the Weidmüller LL 5.08/23/90 3.2SN OR BX PCB terminal block, it is important to verify that the PCB layout supports the intended current distribution and that enough access space remains for installation tools. High pole-count terminals should also be integrated with strong labeling discipline so technicians can identify circuits quickly and accurately.
Because board terminals often become the practical interface between the electronics and the field wiring, they deserve early design attention. Choosing the right pitch and pole count is only the start; usability and clarity are equally important.
