Device Terminal Blocks
Device terminal blocks are made to integrate directly into end-use devices like sensors, actuators, controllers, and small industrial equipment. These terminal blocks allow for clean and reliable interfaces between internal wiring and external field wiring. They are made for both board-level and enclosure-mounted applications, connection methods include screw terminal or push-in terminal, and they're versatile for a range of wire sizes and application needs. Whether an enclosure is mounted to a vibrating platform or suspended in a space with thermal fluctuation, device terminal blocks maintain secure and reliable electrical contact.
Since device terminal blocks are used directly in products, rather than mounted separately on DIN rail systems, they must be space efficient and adaptable. Some models feature mounting plates or snap-in designs to help with installation inside tight enclosures. These terminal blocks can support a variety of connection needs, including single-level and multi-level wiring. They are compatible with a broad range of conductor cross sections. Push-in connection options have become increasingly popular due to their tool-free installation and time-saving advantages, especially in high-volume manufacturing environments.
More Information about Device Terminal Blocks
Device terminal blocks are often chosen for their capability to simplify internal device wiring while still allowing for strong external connections. While they are different from modular terminal blocks and multi-level terminal blocks that are used in control cabinets, they have a similar function to ensure neat, reliable wiring in smaller electronic assemblies. Their design allows for good integration into junction boxes, compact field devices, and applications where standard terminal block connectors are too large or unwieldy. With the addition of flexible connection technology, and with an eye toward accommodating diverse wiring layouts, device terminal blocks can help OEMs achieve clean, safe, efficient wiring in their end products.
FAQs
Are device terminal blocks similar to PCB terminal blocks and terminal strips in that they provide space-saving wiring and easy connection?
Yes, device terminal blocks are similar to PCB terminal blocks and terminal strips in that they provide space-saving wiring and easy, reliable connections for compact devices and electrical assemblies.
Do some device terminal blocks connect conductors to power distribution devices?
Yes, some device terminal blocks are designed to connect conductors to power distribution devices, enabling efficient and organized routing of electrical power within compact equipment or enclosures.
Terminal Blocks Basics
Single Level Pass Through Terminal Blocks are used to connect two wires together with a common junction point. This is helpful when a component needs to be disconnected or isolated within a circuit. These are the most common types of terminal blocks in industrial applications.
Ground Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: they are grounded. These terminal blocks have a metal connection from where the wire is terminated, all the way to the bottom of the block where it will clamp into the panel. This allows for an electrical circuit to be grounded without running a wire to the main ground connection on a breaker or surge protector.
Fused Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: the presence of a fuse. This fuse provides protection for components from too much voltage or current.
Multilevel Terminal Blocks are used to connect two wires together with a common junction point, just like single pass though terminal blocks, but with the advantage of making two electrical connections in the same block. These blocks also incorporate fuses and can be grounded.
Disconnect Terminal Blocks are similar to fused blocks, however the disconnect stops the flow of electricity by lifting a lever on the terminal block. Unlike fuse blocks, they are a more permanent solution, but will not provide any protection in the event of a power surge.
