Wire to board Terminal Blocks are used to facilitate the electrical connection between one or two wires and a printed circuit board. XW4L-09A1-H1 is one of the most commonly used wire-to-board terminal blocks that is widely used in automated control, instrumentation and other circuits. It is a plastic terminal block connector with 4-pole design.

The XW4L-09A1-H1 terminal block connector has 4 rows of terminals with pitch of 9.5mm and row spacing of 5.08mm. Each terminal has a maximum current carrying capacity of 16A and each row can have a maximum voltage of 300V. The material used in the XW4L-09A1-H1 is thermosetting plastic with UL 94V-0 flammability rating, which makes it flame retardant and can withstand temperatures up to 105°C.

The connector is designed with a snap-in style, making it easy to snap-in on the PCB. This terminal has a lock-in feature that prevents the wires from slipping out of the terminals even when they are subject to vibration. The 4 poles of the XW4L-09A1-H1 are connected to one another for reliable electrical connection. It also has a strain relief feature to prevent the wires from moving and breaking the connection. Newer models of the XW4L-09A1-H1 terminal blocks also have the option for mounting with screws for extra security.

The XW4L-09A1-H1 terminal block can be used in various applications that require electrical connections. It can be used in the automotive, robot and industrial control industries, for example. The XW4L-09A1-H1 is also widely used in the telecommunications industry due to its reliable electrical connections.

The working principle of the XW4L-09A1-H1 terminal block is fairly simple. All four of its poles are connected together via its board terminals. When a wire is inserted into the block, it makes contact with the board terminals and is securely held in place. This contact ensures reliable electrical connection and maintains its stability even when subjected to vibration or other movements. The use of the lock-in feature further increases the stability and reliability of the connection.

In conclusion, the XW4L-09A1-H1 Terminal Block is a reliable and efficient way to connect wiring to a printed circuit board. It is easy to install and its lock-in feature ensures a secure and reliable connection. It is widely used in various industries and can be used for both basic and complex electrical connections.
