D-Sub Connectors are an important type of connector used in a wide range of electronics applications including industrial, commercial, and consumer settings.The L77TWC21WA4SMP3SVRM6 is an example of a D-Sub connector. It is a female connector with a male pinout, 25 pins in 2 rows, with 2.54 mm pitch and 12.70 mm row spacing.

Device Profile of L77TWC21WA4SMP3SVRM6

The L77TWC21WA4SMP3SVRM6 features a high profile design, double blade contacts, and level mating orientation. This design ensures maximum contact force is achieved while minimizing insertion and disconnection forces. The interior of the mating portion features a metal-plated high temperature plastic interior to provide a high quality mating interface. The contacts are rated for 10 amp max current and the installed width is 5.08mm.

Application Field

The L77TWC21WA4SMP3SVRM6 is designed for industrial and commercial applications. It can be used in a variety of applications including:

  • Computer motherboards
  • Desktop PCs
  • Instrumentation systems
  • Industrial automation systems
  • Telecommunication systems
  • Consumer appliances
  • Robotics
  • Medical devices
  • Renewable energy systems

Working Principle

The L77TWC21WA4SMP3SVRM6 connector is designed to mate with another compatible connector. The male pins of the connector fit into the corresponding female socket of the mating connector to establish an electrical connection. When the connectors are plugged in, the contacts in the D-Sub connector are pushed back by the female sockets’ pins allowing for a secure connection. This contact system ensures a reliable connection even after the constant stresses of movement, vibration, and environmental changes.

The L77TWC21WA4SMP3SVRM6 D-Sub connector is also designed to prevent accidental mating or mis-mating. This is achieved by the staggered or level mating cutouts on the male and female connections. The male pins will only fit into the female inserts with the same contact and mating cutouts, ensuring that the connectors are properly mated.

Conclusion

The L77TWC21WA4SMP3SVRM6 is a high quality D-Sub connector that is suitable for a variety of industrial and commercial applications. It features a high profile design, double blade contacts, and level mating orientation to ensure maximum contact force is achieved while minimizing insertion and disconnection forces. The male pins and female sockets are designed with staggered or level mating cutouts to prevent improper mating and accidental detachment. All of these design features make the L77TWC21WA4SMP3SVRM6 an ideal choice for electronics applications that require reliable, secure connections.
