PCB Terminal Blocks
PCB terminal blocks offer a convenient means to attach field wiring to printed circuit boards. This is a typical application in industrial automation, control systems, HVAC and OEM equipment, when reliable wire terminations are needed.
PCB terminal blocks are available in fixed or pluggable types. Pluggable terminal blocks make installation easier by allowing the wiring connections to be made before the terminal block is snapped into the PCB base or header. The pluggable PCB terminal block is a popular choice where it is required that wiring can be removed and replaced in a modular fashion.
PCB terminal blocks are offered in screw clamp, spring clamp and push-in connection types. Available in a wide variety of pitches, current ratings and pole configurations to meet many different applications. PCB terminal blocks should be selected based on the type of wire, voltage, current and environmental factors.
FAQs
What are PCB terminal blocks used for?
PCB terminal blocks are used to connect external wiring to a printed circuit board. They provide a secure termination point for power, signal, and control wiring in industrial equipment, control panels, and electronic devices.
What is the difference between pluggable and fixed PCB terminal blocks?
Pluggable PCB terminal blocks consist of a header and a removable plug, allowing for easy disconnection and maintenance. Fixed PCB terminal blocks are soldered directly to the board and provide a more permanent connection.
What pitch sizes are available for PCB terminal blocks?
Common pitch sizes include 2.54 mm, 3.5 mm, 5.08 mm, and larger. The pitch refers to the spacing between pins and must match the PCB design.
Are PCB terminal blocks rated for industrial environments?
Yes, many PCB terminal blocks are designed for industrial use and offer high current ratings, vibration resistance, and secure wire termination methods like screw or spring clamp connections.
How do I choose the right PCB terminal block?
Selection depends on wire size, current and voltage requirements, pitch spacing, connection type (screw or spring), and whether a pluggable or fixed design is needed. Matching these factors ensures proper performance and reliability.
