3.5/3.81mm Plug in Connector Blocks

3.5/3.81mm Plug in Connector Blocks is a type of terminal block connector which allows faster wiring to the terminal block with the help of push-in wire termination technology. They reduce costly downtime and misconnections. Pluggable terminal blocks are available with screw-cage clamp termination, tubular screw termination, or as card edge connectors.

Sun is a professional terminal block manufacturers, providing pluggable terminal block, pluggable connector, and plug in connector blocks. Pluggable Connector opens up more opportunities for terminal blocks to become a more working and flexible connector. One half of the plug, the receptacle, is soldered to the PCB as you would with a standard PCB terminal block. This then creates a header for the plug side of the connector to be connected to. This kind of connection is ideal for maintenance-heavy applications, testing equipment, where a device can be quickly plugged in, HVAC and so many more electrical applications that require some flexibility when it comes to the wiring system. 3.5/3.81mm Plug in Connector Block eliminates the need for unscrewing the wires to disrupt the electrical flow. 

Advantages of 3.5/3.81mm Plug in Connector Blocks

● Free selection of connection technology through uniformly designed COMBI plug-in zone.

● A nominal current of 41 A and a nominal voltage of 1,000 V can be implemented thanks to the powerful plug-in contact.

● Maximum safety, thanks to the touch-proof design.

● Protection against mismatching – thanks to individual coding options.

● Simple potential distribution thanks to double function shaft.

● Vibration resistance: latching accessories available.

● Full flexibility, thanks to connectors for assembly.
