AT04-12PA application field and working principle

Rectangular Connectors - Housings

AT04-12PA is a rectangular connector model, belonging to the AT04 line of connectors manufactured by Amphenol. The AT04-12PA is a 4mm pitch connector that uses a polymer shell material and provide a robust housing for solderless connections that can be used for a variety of applications.

AT04-12PA connectors are typically used in a variety of signals, power, and mixed-signal applications. Instruments and appliances with high levels of electrical noise are particularly suitable for the use of these connector housings. When mated with high-quality, impedance-matched cable assemblies, AT04-12PA connectors are capable of providing reliable performance in extreme environments from -55°C up to 125°C.

The AT04-12PA connector has a single-piece structure, providing a high level of durability. The shell material is also self-extinguishing and RoHS compliant, which makes them suitable for industrial and consumer applications. The shell is comprised of two parts: the front frame and a modular rear frame which includes a strain relief bracket, which helps to secure the cable from pulling out.

The AT04-12PA connector has 12 positions each with a signal contact. The contacts are supplied in either 0.64mm or 0.76mm square or crimp configurations. The contacts are held in place by two levers on each side of the connector, which enables effortless connection and can help to reduce installation time. The contacts are sealed with a special shield, providing excellent mechanical and electrical performance. The contacts are also fully compliant with IP20 standards, ensuring reliable operation even in dusty or damp environments.

The AT04-12PA also has a range of mounting features. It has a flange-mount and snap-in-mount attachment system which provide stability and protection against vibration and shock. It also has a special latch locking system which allows for a secure connection without additional fastening.

Overall, the AT04-12PA connector is suitable for a wide range of industrial and consumer applications. Its robust construction, high level of electrical performance, and broad temperature range make it an excellent choice for reliable connections in extreme environments. Moreover, its range of mounting features ensures that the connector can be securely mounted in a variety of applications.
