DF81-50P-SHL

Rectangular Connectors - Accessories are mainly used to provide reliable electrical connections in numerous applications, like those used in industrial automation, transportation system, and medical equipment. The DF81-50P-SHL (hereafter called the DF81) is an example of such product in the rectangular connectors market. This article will explain the application fields and working principles of the DF81.

Application Fields of the DF81

The DF81 is typically used in automotive, marine, and aviation electronics, including navigation systems, airbags, and engine systems. It is also used in medical equipment due to its superior sealing performance and high reliability. In addition, it is a popular choice for industrial equipment, such as PLCs, PC-controlled systems, industrial robots, and machine controllers, where its high signal integrity and rugged construction ensure reliable connections in harsh environments.

Working Principle of the DF81

The DF81 is a rectangular connector with two plastic housings, each containing several socket contacts. The contacts are made of an alloy of copper and tin and specially treated to ensure optimal contact and seal performance. The contacts are held in a two-piece shell that is secured with a metal latch system. As a result, the connector has a high degree of electrical insulation and protection from environmental hazards such as temperature, vibration, and dust.

When two DF81 connectors are mated, the contacts on each connector make electrical contact with one another. This contact is maintained by the latching system on the connector, which prevents the connectors from coming apart when under high pressure or vibration. As such, the DF81 ensures reliable electrical connections in harsh environments, even when subjected to long-term usage or vibration.

In conclusion, the DF81 rectangular connector is a reliable product that can be used in a variety of applications, including automotive, marine, and industrial automation. Its superior sealing performance, high signal integrity, and rugged construction make it a particularly suitable choice for harsh environments. As such, it is a popular choice among industrial equipment manufacturers, medical instrument makers, and those in the aviation and automotive industry.
