The LAA4/0-12-5 is a four pole/12 pole, 5mm pitch rectangular connector. It is widely used in high-voltage and high-speed circuits, especially for telecom, computer and consumer electronics applications. In addition, it is also used in automotive and aircraft industries.

Overview

The LAA4/0-12-5 rectangular connector features four-pole and 12-pole contact layouts, with a 5mm pitch. This rectangular connector is rated for mating cycles of more than 500, and its insulation resistance and dielectric strength are both superior. The maximum current rating for the LAA4/0-12-5 rectangular connector is 6A with AWG 20-28 copper conductor.

The contact is designed as a plastic "pin" type, with an embedded brass plated and gold-plated contact. The pin and socket contacts are designed in a locking mechanism, which guarantees secure mating. The mating interface is designed with smooth ergonomic shape, which improves the tactile feel at the time of mating and coming.

The housing material of the LAA4/0-12-5 rectangular connector is UL 94V-0 classified polyamide. It is available in three-piece construction, comprising of the receptacle, a cable to board connection and a plug. The LAA4/0-12-5 rectangular connector is flexible in various configurations such as 90° board, 45° board and cage clamp.

Construction

The LAA4/0-12-5 is a three-piece connector system comprising of the receptacle, the plug and the cable-to-board connection. The receptacle is the largest part of the system, with the plug being slightly smaller. The three components together are designed in a non-directional mating interface.

The receptacle comprises of a housing shell, a contact holder, elastomeric seals and a metal face plate. The housing shell has two locking tabs, which secure the contact holder to the interface. The contact holder contains the pins and sockets, and can be easily removed for cleaning and inspection. The elastomeric seals provide protection from dirt and moisture. The metal face plate holds the housing in place.

The plug comprises of a housing shell, a contact holder, seals and a metal face plate. It is designed with the same components as the receptacle, but in a smaller size. The plug is secured to its interface by locking tabs.

The cable-to-board connection comprises of two parts: the plug part and the receptacle part. The plug part consists of a metal body, a contact holder and a plastic housing. The contact holder contains the pins and sockets, and the metal body holds the contact holder in place. The receptacle part is designed with the same components as the plug part, but in a smaller size.

Mechanical Properties

The mechanical properties of the LAA4/0-12-5 rectangular connector are designed to meet the demanding environments. The connector has a mechanical life rating of greater than 500 cycles, and can be subjected to continuous vibration and temperature cycling.

The connector has superior insulation resistance and dielectric strength which is essential for high-voltage and high-speed applications. It has a temperature range of -25°C to +85°C, and can resist harsh conditions such as salt spray, humidity and corrosive elements. Moreover, the connector has a minimized fluorine emission, ensuring a safe and reliable operation.

Application Field and Working Principle

The LAA4/0-12-5 is a versatile and reliable connector, which is used in various applications such as telecom, computer, automotive and aircraft industries. With its superb mechanical properties, it is an ideal choice for high-voltage and high-speed circuits.
