The A-TB381-TV21SB is a part of the Terminal Blocks - Wire to Board family. This type of terminal blocks is used to connect two or more electrical wires to the same contact terminal. It is designed for high density wiring applications, making it suitable for many different projects. It features an easy-to-use spring cage technology that allows users to make quick, reliable connections. The product also features a high-quality insulation coating to protect the wires and contacts.

The A-TB381-TV21SB is made of a high-grade plastic material, with a copper plating and a UL 94 V-0 flame-retardant rating. It has 5.0mm pitch and 6.2mm width, making it easy to connect and disconnect wires. The terminal has a voltage rating of 400VAC and a maximum current rating of 17A. It is rated to a minimum insulation resistance of 100MΩ-DC at 500VDC, and can withstand temperatures of -40°C to +120°C and humidity of up to 95%.

A-TB381-TV21SB is used in a wide range of applications, including industrial, automotive, medical and consumer spaces. It is also suitable for situations that require connections and disconnections under high voltage. It can be used in the manufacturing of computer products, automation systems and medical devices. It is often used in safety applications, including emergency stop wiring, LED pneumatic circuitry and alarm systems. Other common applications include charging systems, outdoor lighting, building automation systems and robotics.

The working principle of the A-TB381-TV21SB terminal block is fairly simple. When the terminal is connected to a live current source, it securely holds the two wires in place and transfers the energy from one to the other. This happens when a connector is inserted into the spring cage, compressing the two wires and creating an electrical connection. The contact terminals are then securely held in place using a clamping nut. This ensures that the connection is secure and won’t come loose even with high levels of vibration. The terminal also features a double-ended design, allowing users to conveniently disconnect the wires with ease.

In summary, the A-TB381-TV21SB is a high quality terminal block system designed specifically for high-density wiring applications. It is a part of the Terminal Blocks - Wire to Board family, and is suitable for many industries. The product features a spring cage design for easy connections, and is rated for a voltage of 400VAC and a maximum current rating of 17A. The product is used in a wide range of applications, including industrial, automotive, medical and consumer spaces. The working principle is the same for all terminal blocks of the Terminal Blocks - Wire to Board family, and involves a clamping nut mechanisms for secure connections.
