The STMM-105-01-S-D-LC is a rectangular connector from the Headers, Male Pins series. It’s designed for crimp contacts. This connector is formed from two parts - a female header and a male pin.

Application Fields

The STMM-105-01-S-D-LC series is commonly used in a variety of industries, such as automotive, aviation, industrial, lighting and medical equipment. Industrial applications, for instance, can benefit from the robustness of this series, as it has a high temperature range (ambient temperature range from -40°C to +110°C). Moreover, the connector provides a reliable and robust connection even under harsh conditions (vibration and shock, over-current and abnormal atmospheric conditions).

The automotive industry can also benefit from the use of STMM-105-01-S-D-LC connectors, due to its dust and waterproof protection rating up to IP67, wich ensures proper operation even in the most rugged environments, including a high salt environment such as near the sea. Aviation applicatons, on the other hand, benefit from the connector\'s ease of assembly and robustness.

Working Principle

The STMM-105-01-S-D-LC series has two pieces: a male pin and a female header. The male pin is intended to be mated with one of the STMTM-105-02-S-D-LC female headers. The male pin\'s contact points are inclined to ensure a reliable and low-resistance contact with the female header’s contact points. This inclining of the contact points increases the contact surface area, and thus decreases the current load and dissipates heat more uniformly.

The mating operation requires a press-locking to secure the connection, as the male pin is press-fit into the female header contact pins. The male pin is keyed to allow proper connection to the appropriate female header. The plastic body and composite contact pins ensure proper insulation, and the current load can be adjusted to the application requirements.

Conclusion

The STMM-105-01-S-D-LC series is a highly versatile, reliable and robust rectangular connector. It has a wide range of applications in the automotive, aviation, industrial, lighting and medical equipment industries. It has a high temperature range and an excellent dust and waterproof protection. The connector’s reliable and robust contact points, along with its good insulation, makes it suitable for high current applications. The press-fit and keying system ensures a secure connection in any application.
