Weidmüller 1007120000 SL 5.00/02/90B 3.2SN GN BX PCB Plug Connector Guide
The Weidmüller 1007120000 SL 5.00/02/90B 3.2SN GN BX PCB plug connector is part of the OMNIMATE style connection world where reliable board-to-wire interfaces are required in compact electronic and industrial control designs. For engineers searching for a 2-pole PCB plug connector with a 5.00 mm pitch, this model stands out because it combines a familiar form factor with straightforward electrical data and practical installation geometry.
This connector is specified as a PCB plug-in connector with THT solder connection, a 5.00 mm pitch, and 2 poles. Product data lists it at 400 V / 18 A according to IEC and 300 V / 15 A according to UL. It is supplied in box packaging. One especially important lifecycle detail is that the product is marked discontinued, with a listed last order date of 31.08.2025.
Understanding the Weidmüller 1007120000 PCB Connector
The Weidmüller SL 5.00/02/90B PCB connector is intended for applications where a removable or pluggable board connection helps simplify assembly, service, or modular product design. Instead of wiring permanently into a PCB terminal, the connector concept supports organized mating and replacement at the connection interface.
For electronic control systems, power distribution on compact boards, industrial control units, and embedded device assemblies, this can improve handling during production and maintenance. A 2-pole design is often used when a clean two-wire connection path is enough, especially in compact product architectures.
Technical Highlights That Matter
The most important baseline features of the Weidmüller 1007120000 SL 5.00/02/90B 3.2SN GN BX PCB plug connector are its 5.00 mm pitch, 2-pole arrangement, and through-hole solder connection. These features influence not just electrical capacity, but board layout, creepage planning, assembly workflow, and connector accessibility.
The listed IEC rating of 400 V and 18 A suggests it can support more than very low-power signaling, while the UL rating of 300 V and 15 A is also useful for engineers working across approval frameworks. In practical terms, this makes the connector more relevant for compact device wiring and industrial electronics where board-level interconnection must remain mechanically secure and electrically clear.
Lifecycle and Design Planning Considerations
A major point for specifiers is the lifecycle status. Because the Weidmüller 1007120000 PCB plug connector is marked as discontinued, it should be handled carefully in new product development. Existing systems, maintenance support, and controlled replacement scenarios may still justify its use where approved stock and lifecycle planning are already in place. For fresh designs, however, engineers usually need to verify successor options or equivalent compatible families before finalizing the BOM.
This does not reduce the usefulness of the product in documentation or maintenance contexts. In fact, discontinued connector references are often highly relevant for service teams, retrofit engineers, and procurement professionals trying to understand legacy equipment bills of materials.
Typical Application Context
The Weidmüller 1007120000 connector fits control electronics, interface boards, small power modules, and compact device housings where pluggable wiring improves manufacturability. A 90-degree form factor can also support more efficient board edge orientation in products with limited internal height or defined cable routing geometry.
In production environments, pluggable PCB connectors often help separate wiring work from board assembly work. That can make inspection cleaner and service interventions faster, especially when boards must be replaced without rebuilding the entire wire termination setup.

FAQ
What type of product is the Weidmüller 1007120000?
It is a PCB plug-in connector with THT solder connection, 5.00 mm pitch, and 2 poles. It is intended for board-level pluggable wiring interfaces.
What are the electrical ratings of the Weidmüller SL 5.00/02/90B 3.2SN GN BX?
The published product data lists 400 V / 18 A under IEC and 300 V / 15 A under UL. These values should always be matched against the overall device design and applicable standards.
Is the Weidmüller 1007120000 still active?
No. The product is listed as discontinued, and a last order date of 31 August 2025 is shown. That makes lifecycle review essential before using it in any new project.
Why does connector pitch matter in PCB design?
Pitch influences board layout, creepage and clearance planning, conductor spacing, and overall compactness. A 5.00 mm pitch PCB connector offers a useful balance between electrical spacing and manageable board density in many industrial electronics designs.
Where is this connector typically used?
It can be used in control electronics, industrial devices, compact interface modules, and serviceable PCB assemblies where a removable board-to-wire connection is beneficial.
Should this part be used in new designs?
Only after a careful lifecycle assessment. Because it is discontinued, many engineering teams will prefer an active equivalent for new development while keeping this part number mainly for maintenance, documentation, or legacy system support.
