Specifications

The 91921-31109 Connector features field-terminable terminals that are polarized for protection against reversed wiring. Its high contact retention force and dielectric strength guarantees reliable performance. The insertion depth is 6.1mm, and the connector comes in a variety of configurations with 6, 10, 14, 19, or 25 rows.

Working Principle

The 91921-31109 Connector utilizes the edge contact type where contact forces are applied to the edge of the Connector. The contact force is provided by a pair of edge-bonded leaf springs that create a reliable contact between the male and female contacts. The self-compensating leaf spring design ensures reliability and durability even in high-vibration environments.

Installation

The 91921-31109 connector is designed for easy installation in a variety of applications. The surface mount connectors are installed flush to the board surface, with the self-compensating leaf springs providing the contact force to the board. The low-force latching contacts provide secure connections without the need for soldering.

Durability

The 91921-31109 Connector uses a self-compensating leaf spring design to ensure reliability and durability in high-vibration environments. The stainless-steel pins provide corrosion resistance while the rugged housing offers superior protection against dust, humidity, and mechanical damage. The connector is rated for 5,000 mating cycles and is UL approved for automotive applications.

Conclusion

The 91921-31109 Connector is a reliable, high-performance rectangular connector that is ideal for board-level interconnections. Its superior contact retention force, fast and easy installation, and high durability make it a superior solution for a variety of applications.
