Weidmüller PCB (Printed Circuit Board) connectors are components used to connect wires to printed circuit boards, facilitating signal, data, or power transmission. These connectors ensure secure, durable, and efficient interconnections in industrial and automation applications.
Weidmüller is a German company known globally for top-tier electrical connection technology.
📚 Types of Weidmüller PCB Connectors
Weidmüller has a wide variety of PCB connectors, categorized mainly by connection type, mounting style, and application area.
1. Terminal Blocks for PCB
Known as PCB terminals, they allow wire-to-board connections.
Available in screw, spring, or push-in technology.
Subtypes:
OMNIMATE Signal – For signal processing
OMNIMATE Power – For power electronics
OMNIMATE Data – For data interfaces
2. Pluggable Connectors
Two-part system: header (on PCB) + plug (for wire)
Great for easy maintenance and modular systems
Available in vertical or horizontal plug-in directions
3. Wire-to-Board Connectors
Allow direct connection between field wiring and the PCB
Often use push-in or spring clamp technologies for tool-free wiring
4. Header Strips
Mount directly on PCB (THT or SMT)
Designed to interface with a female plug connector
🔩 Connection Technologies Used
Type Description
Screw clamp Traditional, very secure, good for power applications
Push-In Tool-free, quick install, ideal for automation systems
Spring clamp Vibration-resistant, good for tight spaces and mobile environments
Wire guard Prevents wire damage while securing with screws
🛠️ Mounting Styles
THT (Through-Hole Technology) – For high mechanical strength
SMT (Surface Mount Technology) – For compact, automated soldering
THR (Through-Hole Reflow) – Combines mechanical strength of THT with SMT process advantages
