Terminal blocks – Wire to Board allow efficient connection and disconnection of wires to PCBs. The 1546216-3 is a screwless terminal block plug connector that enables easy, secure, and reliable connections and disconnections of wires to a printed circuit board (PCB). It offers reliable connection between two electrical wires and the associated PCB. This guide explains the important characteristics of 1546216-3, its application field, and its working principle.

Overview of 1546216-3

The 1546216-3 is a three-way screwless terminal connector from the 1546xxx series made from gray polyamide (PA) that consists of two contact blocks, coupling links, and terminals. The contact blocks and coupling links come in a one-piece integrated design, which makes it easy to mount and use. Each contact block has six positions with a spacing of 5.08mm, offering reliable electrical connection. The contact blocks are lubricated and gold-plated with silver – enabling corrosion resistance and avoiding problems with oxidation.

Each terminal has two integrated wires – an outer wire circumference and a core insulated wire. The contact blocks, which are 0.45mm wide, offer reliable electrical connection due to the 0.2mm contact gap. The MIL-STD-202 characteristics ensure durability and robustness and the connection is reliable. The terminal blocks is equipped with a push-in spring mechanism that enable easy and fast connection and disconnection of wires.

Application Field

The robust construction of the 1546216-3 makes it suitable for a wide range of applications. It is widely used in the industrial, medical, and consumer electronics industry in applications such as PCBs, computers, electronic appliances, automotive, and consumer electronics. It is also used as a test and measurement connection block in sensor signal applications such as transmitters and receivers.

The 1546216-3 is also widely used in harsh and vibratory environments due to its high resistance to shocks and vibration. It is designed for vertical mounting and offers secure connection for a range of connection systems such as hand soldering, autoclave systems, and connection with 0.5mm terminals – making it suitable for various applications.

Working Principle

The 1546216-3 has two contact blocks – one that is used for signal connections and another for power connections. The signal connection contact block consists of two rows of terminals and the power contact block consists of three rows of terminals. The connectors are color-coded – blue for signal and red for power connection.

To make the connection, the wires are inserted into the connector and the mechanism at the end of the terminal will automatically engage and close the connection. This ensures secure contact between the two wires and the terminal blocks. The terminal lock spring ensures that the connection stays secure and does not get loosened. The termination of the cable can be easily disconnected by pressing the release button. This will open the connection and allow easy removal of the wires.

The 1546216-3 is a highly reliable and easy to use connector that offers cost-effective, secure, and quick connections and disconnections of wires to a PCB. It is suitable for a variety of applications in the industrial, medical, and consumer electronics industry.
