Terminal blocks have been used in industrial electrical wiring for many decades due to their reliable connection of wires and devices. The A-TB500-TL20SB terminal block is specifically designed for wire-to-board connection in harsh environmental conditions. It is suitable for multiple applications including power, measurement, signal, and communications.

Construction

The A-TB500-TL20SB is a 2-pole, 20A terminal block with a 7.62mm pitch. It is constructed from a flame retardant PA6 GF30 material which is designed to withstand high temperatures, making it ideal for use in applications such as industrial ovens and furnaces. The terminal block has three slots along its base on which the wires can be connected, and an angled top which ensures that the wires are firmly held in place by the pressure applied by the retention screws.

Features and Benefits

The A-TB500-TL20SB is designed to be easy to use. It has spring-cage technology which allows for simple and secure mounting of the wires, making the terminal block accessible and user-friendly. The terminal block also has integrated LED indicators which provide a visual display of the wiring status, eliminating the need for manual inspection. It also features a reverse-polarity protection system which prevents damage due to incorrect wiring.

The A-TB500-TL20SB is designed for use in harsh environments. It meets the IP67 standard for water and dust resistance and is shock and vibration resistant. It can also withstand temperatures up to 150°C, making it suitable for use in high-temperature applications such as furnaces and ovens. The terminal block can also be connected to other compatible terminal blocks easily to extend the wiring scope.

Applications

The A-TB500-TL20SB is suitable for various applications including power, measurements, signals, and communication. It can be used as a component for connecting wiring in industrial ovens and furnaces, in automotive, factory automation, and process control installations, and for indicating voltage changes within electrical circuits. It can also be used in smart home applications such as security systems, doorbells, and lighting installations.

Working Principle

The A-TB500-TL20SB uses a screw-clamp fastening system which is designed to securely hold the wires in place. This is achieved by applying pressure to the wire using the screws on the terminal block. The spring-loaded cage of the terminal block holds the wires firmly in place by exerting an outward pressure which is applied by the pressure screws at the top of the terminal block. The tension of the screws can be adjusted using a suitable tool, ensuring the wires are firmly secured in place.

The reverse-polarity protection system of the terminal block also ensures that the wiring is correctly applied in order to ensure connections are safe and secure. The integrated LED indicators also provide a visual indication of whether the wiring is correctly connected, allowing for quick and easy troubleshooting.
