Weidmüller 1001970000 PCB Terminal Block: Features, Wiring Context, and FAQ
The Weidmüller 1001970000 PCB terminal block, formally identified as Weidmüller LL 5.08/16/90 3.2SN OR BX PCB terminal block, is a board-level connection component developed for dependable industrial wiring. It is used where engineers need a practical balance between pole density, conductor security, electrical capacity, and service accessibility on printed circuit boards.
This model is part of the OMNIMATE Signal LL family and provides a 16-pole configuration with 5.08 mm pitch. It is designed for through-hole mounting, supports a 90° horizontal wire exit, and uses a proven clamping yoke screw connection. In many industrial electronics projects, this combination remains attractive because it supports maintainable wiring without forcing designers into overly tight handling conditions.
Technical Profile of Weidmüller 1001970000
The Weidmüller 1001970000 printed circuit board terminal is rated for 500 V and 32.5 A according to IEC data, with a conductor range of 0.5 to 6 mm². Under UL, it carries a rating of 300 V and 20 A, with supported wire sizes from AWG 26 to AWG 12. The solder pin length is 3.2 mm, the contact area is tinned, and the housing color is orange.
For engineers evaluating PCB terminal blocks, this specification set covers many of the high-priority selection criteria: electrical rating, conductor compatibility, mounting style, pole count, and mechanical connection reliability. The use of a clamping yoke system is especially relevant in environments where vibration resistance and repeatable clamping behavior are important.
Where a 16-Pole PCB Terminal Block Fits Best
A 16-pole PCB terminal block is often a practical choice when one board has to manage multiple field inputs, actuator outputs, or mixed signal lines in a compact industrial design. It can be used in building automation devices, motor control interfaces, process electronics, instrumentation subassemblies, and machine control cards where wiring density is meaningful but not excessive.
The Weidmüller 1001970000 wire-to-board terminal block is particularly useful in horizontal routing schemes. Because conductors leave the terminal at a right angle, the installed wiring can run neatly along the enclosure wall or into cable ducts. That is valuable in systems where space planning matters as much as electrical performance.
Design Advantages in Industrial Electronics
Industrial designers frequently look for components that reduce rework risk during assembly and remain easy to service after installation. In that context, the Weidmüller 1001970000 PCB screw terminal block offers a familiar connection method with good usability. Through-hole mounting supports mechanical anchoring to the board, and the clamping yoke concept is well known for accommodating common conductor types in industrial practice.
Another benefit is traceable compatibility with standard search behavior. Engineers and procurement teams often search for phrases such as Weidmüller 1001970000 PCB terminal block, Weidmüller 1001970000 terminal block, Weidmüller 1001970000 wire to board connector, and Weidmüller 1001970000 printed circuit board terminal. Those usage patterns reflect how the part is evaluated in technical sourcing and replacement workflows.
Application Notes for Better Long-Term Performance
To get the best performance from the Weidmüller LL 5.08/16/90 3.2SN OR BX PCB terminal block, board designers should coordinate conductor cross-section, copper area, torque control, thermal loading, and enclosure ventilation. High nominal ratings are useful, but they deliver real value only when the PCB layout and installed conditions support them.
It is also helpful to think about documentation. Marking terminal positions clearly on the board and matching them to cabinet wiring drawings reduces installation risk. In control engineering, seemingly simple components such as PCB terminals often have a major influence on commissioning speed and maintenance clarity.
FAQ: Weidmüller 1001970000 PCB Terminal Block
What type of product is the Weidmüller 1001970000?
The Weidmüller 1001970000 is a 16-pole PCB terminal block intended for wire-to-board connections. It belongs to the OMNIMATE Signal LL series and uses a clamping yoke screw connection.
What is the pitch of the Weidmüller 1001970000 PCB terminal block?
The pitch is 5.08 mm, which is a widely used dimension in industrial PCB terminal design because it balances wiring access and connection density.
Is the terminal angled or straight?
This model uses a 90° conductor outlet, meaning the connected wires exit horizontally relative to the PCB.
What wire range does it support?
The published data shows support for 0.5 to 6 mm² conductors under IEC and AWG 26 to AWG 12 under UL conditions.
Why would engineers choose a clamping yoke PCB terminal block?
Clamping yoke terminals are popular because they provide a reliable and established screw-based wire termination method. They are often selected for industrial environments where serviceability, conductor security, and straightforward maintenance matter.
Can the Weidmüller 1001970000 be used on custom automation boards?
Yes. It is well suited for custom automation PCBs, control interfaces, instrumentation boards, and building technology electronics that need a durable wire-to-board terminal solution.
