Terminal Blocks - Barrier Blocks

The T37123-21-0 application field is used for connecting electrical wires in different applications. This terminal block is primarily employed with wiring when device level flexible connections are desired. It is used for assembling and bundling wires. The workpiece size is very small, so it is suitable for narrow space connections and maintenance.

Description

The T37123-21-0 terminal block is a barrier terminal block with a push-in function. The casing of the block is made of a polyamide plastic with halogen-free materials. The terminal block has a width of 19.8 mm and a depth of 22.5 mm and a height of 11.2 mm. The surface is printed with labels to facilitate wiring. The lead spacing is 7.5 mm and the screw pitch is 5.0 mm. The pinout type is 30-pin with snap-in clamps and screw holes.

Circuit Design

The T37123-21-0 comprises of two terminals which are connected in parallel with the common connection. This terminal block is mostly used when two circuits need to be connected together where one of the circuits is wired outside the casing. The block is equipped with two equal connection lugs, slot-shaped screw holes, two removable clamps and can accommodate a maximum conductor area of up to 0.5 mm2 (24 AWG). The terminals use the same color to indicate the connections and this helps in connecting the wires easily. This terminal block also has an integrated ground connection.

Working Principle

The T37123-21-0 terminal block works on the principle of connection and disconnection. Its unique Push-in and Lock (PiL) technology allows users to make secure and simple connections in a matter of seconds, without the need for a tool. This terminal block makes it easy to install wire and securely connects and disconnects the wire while keeping the electrical connections stable and safe. To connect two devices, the user simply needs to insert the stripped cable into the connector and press it into place. To disconnect two devices, the user needs to push the button for the ejector spring and the pins release the cable.

Advantages

The T37123-21-0 terminal block offers various benefits to users. Its small size allows for easy installation in tight confined spaces. The shape of the housing offers high mechanical stability and the high-grade pin terminals with designations make it legible once programmed. The snap-in clamps makes the connections secure and sealed, thus preventing short-circuits and increasing the reliability and durability of the terminal block. The integrated ground connection reduces the wiring process and eliminates the need for extra space. It is compatible with PCBs in a wide range of densities and is also capable of resistance to mechanical, electrical and temperature shocks.

Applications

The T37123-21-0 terminal block can be used in a variety of applications such as signal and data transfer in automotive, industrial, machinery, and consumer electronics. This terminal block is used for connecting audio, video, alarm systems, computer power supplies, USB connectors, modules, PLCs, and other external data processing equipment. It is also used for ground wiring purposes and for grounding isolated devices.
