This connector is widely used in a variety of electronic systems, including industrial machinery, automotive, medical, and other applications. In this article, we will discuss the 71991-840LF application field and working principle.

1. Application Field:

  • Industrial machinery: the 71991-840LF connector can be used in industrial machinery such as pumps, engines, or HVAC systems. This is due to its ability to handle high levels of vibration as well as its ability to maintain strong connection in wet environments. Additionally, the connector is designed to protect against dust, liquid, and dirt, making it ideal for use in dusty or wet industrial applications.
  • Automotive: the 71991-840LF connector is also widely used in automotive applications such as fuel injection systems and ABS brakes to provide reliable electrical connections. The connector is also used to connect various body control modules and audio systems. Due to its ability to handle high vibration levels, the 71991-840LF connector can be used in demanding automotive applications.
  • Medical: the 71991-840LF connector can be used to connect various medical electronics. It is designed to resist vibration and maintain a strong connection. It also has an acoustic shielding design which ensures that vibrations and signals do not interfere with each other.
  • Other applications: This connector is used in a variety of other applications such as robotics, military, consumer electronics, and telecommunication systems.

2. Working Principle:

The 71991-840LF connector consists of two components, a male connector and a female connector. The male connector has two insulated sockets, and the female connector has two detachable mating blades. When the two connectors are mated together, the two blades on the female connector slide into the slots on the male connector and form a tight connection. The connectors are designed to ensure a reliable connection even when exposed to vibrations or harsh environmental conditions.

The 71991-840LF connector has several advantages over other types of connectors. First, it is designed to provide high-level electrical protection, meaning it is resistant to electrostatic discharge (ESD) and high voltage surges. It also provides excellent mechanical protection due to its robust design and its ability to resist high vibration levels. The connector also features an acoustic shielding design which ensures that vibrations and signals do not interfere with each other.

In conclusion, the 71991-840LF is a popular rectangular connector designed to provide high-level electrical and mechanical protection in a variety of applications. It is widely used in industrial machinery, automotive, medical, and other applications due to its robust design and its ability to resist extreme vibrations. The two components, a male and a female connector, are designed to provide a reliable connection even when exposed to harsh environmental conditions.
