It is also used in process controls, which is why it was designed with a wide array of features.

Working Principle

The 71991-339LF connector is composed of two major components: the matrix and the limiting element. The matrix is the main part, and is comprised of contacts spaced at a regular intervals between two slides. These contacts have a contact force of 10N, which is important for signaling and current flow. The limiting element is made of an elastomeric material that helps to regulate the flow of electricity and signal, and provides physical protection from moisture and EMI/RFI.

The contacts in the 71991-339LF connector are made of high conductivity copper alloys, which allows for a good contact rate and good physical protection when in contact with electronic components. Additionally, the contacts have shielded soldered points, which adds further protection to the connection. They also feature recessed sockets designed to increase wear resistance of the contacts.

The 71991-339LF connector also has two rows of self-locking straps. These straps help to protect the contacts from external influences, such as jerks and bumps. Additionally, the contacts of the 71991-339LF connector are further protected by two layers of insulating plastic and O-ring seals that make the connections airtight and dustproof.

Conclusion

The 71991-339LF is a reliable standard straight-plug-type rectangular connector used in many application fields. It offers good signal and current rating, hermetic seals for controlling air contaminants, wide array of features, contacts made of high conductivity copper alloys, shielded soldered points, and two layers of insulating plastic and O-ring seals for protection. All these features make the 71991-339LF connector a reliable connection solution for electronics and telecommunications industry.
