The 71991-415LF head is one of many popular connectors with many specific features and functions that make it a great choice for various scenarios. This article explains the application field of this connector and its working principle.

Application Field

The 71991-415LF head is a low-profile connector that is well-suited for use in tight, high-density applications. It is designed with a 0.082" (2.1mm) pitch and a reduced height thermoplastic housing, which makes it ideal for applications with limited space or areas where flexibility is key. This connector is available in single-row and dual-row varieties and is suitable for use in a variety of markets such as medical, automotive, consumer electronics and industrial automation.

The 71991-415LF is rated for use in temperatures ranging from -55°C to +125°C and has a current rating of 3.0A. The contact terminal is made of tin-plated brass and is sealed to prevent dirt or dust from compromising the connection. This makes the connector a great choice for use in harsh environments and applications where moisture or vibration may be a concern.

Working Principle

The 71991-415LF head is designed with a spring-loaded retention clip, which locks the connector in place. This ensures that the connector stays in its desired position and provides a reliable connection even in environments with shock and vibration. The connector also features a positive latching system, which greatly reduces the possibility of accidental disconnection.

The contacts for the 71991-415LF head feature a 3-channel design which helps to ensure reliable mating. The highest contact is larger than the others and is designed to ensure correct polarity when mating with the corresponding female connector. Additionally, this connector features a polarizing pin to prevent mating with incompatible connectors.

The 71991-415LF head is UL-approved and meets the UL 94 specifications for flammability and is RoHS compliant. It has also passed the Mating and Unmating tests. However, it is important to note that this connector is not designed for use in applications where additional shielding is required.
