Entrelec has been the leading manufacturer of terminal blocks for over 50 years. Entrelec terminal blocks are used all over the world in a diverse range of markets including automotive, machine tool, process control, factory automation, railway, panel assembly, HVAC, chemical, and energy. All Entrelec terminal blocks meet the highest industry standards are available in space saving DIN rail mountable modules. TE Connectivity now includes the Entrelec terminal block line in their extensive industrial portfolio. By adding Entrelec’s terminal block offering from TE Connectivity, Electro-Matic can offer a complete system for power, signal, and data connectivity with a special focus on harsh environments.

Entrelec offers space-saving industry standard din-rail mountable terminal blocks in various colors, functions and connection technologies that carry worldwide approvals.

3 Technologies of Entrelec Terminal Blocks

The SNK series offers three exclusive connection technologies. The screw clamp technology, for heavy-duty connections, ensures a reliable and safe screw connection for more than 70 years. Second, the patented PI spring technology, providing benefits of both push-in and spring technologies in one connection. Lastly, the pluggable technology, which allows a plug-and-play connection increasing productivity and contributing to secure the installation. The SNK series is specifically designed to ease panels manufacturing, and provide significant productivity savings from the design, assembling, maintenance, and logistics steps in your project.

Smart Terminal Block Connections

Because our smart connection technologies match more than 80% of worldwide practices, your projects become more productive and run more efficiently. While our clamp is made of hardened steel that makes the connection reliable, what really sets us apart is the exclusive anti-release system that reduces the need for retightening and offers high torque resistance. the PI spring technology offers the benefits of two technologies in one connection. The first, a pushing mode for a direct one-step insertion of wire with efficiency and speed, or the spring mode with screwdriver that is well adapted to long series that provide a reduced effort and conductive preparation time. Pluggable technology optimizes every manufacturing operation. It allows sub-assembly concepts using a serialized production of the harness while securing on-site installation. When using PI spring and pluggable connections, you can save up to 90% in mounting time.

Common Accessories

Common accessories between the SNK series are rationalized to fit several blocks, reducing your inventory by up to 50%. The screw clamp range technology uses only one end section for all sizes, and on the PI spring range technology one circuit separator is common to 62 different turmoil blocks. All SNK terminal blocks can be marked on both sides using universal terminal marking tabs. Plotter systems are available to mark all Entrelec terminal block markers.

Design and Features of SNK and DBL Terminal Blocks

The clever design of our accessories streamlines the assembling process. Our plugin jumpers are rated 1000 volts and don't require any separators when installed. They are available from 2 to 50 poles for reduced inventory to perform alternate jump rate. Plug in jumpers integrate pre-cut poles that can be removed without tools and leave a clean cut. Predefined shapes and molding allow cut poles to be easily identified. Our parallel component plug allows insertion of components between two standard blocks without touching the wiring which is a great feature for troubleshooting operations.

Our isolated test devices allow simple voltage test when plugged into the central channel while our test connector can be configured to test up to 15 circuits at the time. Simply snap the various parts together to create your own connector to measure inject current or voltage signals. The connector is guaranteed for 1000 volts and 10,000 operations. Our special shape markers are interchangeable and cannot slide or fall off the terminal block. Smaller markers can fit any bigger block, and our rotating market holder fits on any 5.2 millimeter spacing terminal block and accepts up to 3 markers. The rotating function simplifies the wiring on multi-level terminal blocks while providing high marking visibility for automation applications. You can protect signal integrity with our shield connector by simply using plastic collars to connect the cable shield onto the connector.

Easy Installations and Accessories

SNK series is easy to install and reduces mounting time by up to 70% thanks to our screwless accessories and functions such as snap-on ground connection plug-in jumpers plug-in test devices and test connectors locking devices endstops and markers.
