Circular Connectors come in a variety of designs and implementations.Today’s market offers a wide selection of these interconnects with multiple configurations and features. The SD-40LP connector is a type of circular connector that is well-suited for a variety of applications and environments.

The SD-40LP was designed as an advanced interconnect solution with superior protection performance and reliability in harsh environmental conditions. This connector is a low-profile, highly efficient, lightweight miniature connector for use where higher power levels are needed and bulkier alternatives aren’t practical. The SD-40LP is designed for a range of applications, including military/defense, radio communications, transportation, telecommunication, networking, computing, industrial control, medical, and instrumentation.

Profile

The SD-40LP circular connector is a low-profile, lightweight connector with a threaded coupling nut and reverse bayonet coupling. It is a shell size 40 connector and comes in a variety of configurations and turntable arrangements, including 9-to-50 pin. It offers excellent protection against EMI/RFI, has low insertion loss, and high salt spray resistance.

Features

The SD-40LP connector features a highly efficient design that meets the high performance standards for demanding application fields. It has an operating temperature range of -55° to +125°C and a mated pair impedance of 100Ω.

The SD-40LP connector includes a snap-in coupling mechanism that ensures stable connection and reduces assembly time, and features two polarization positions that guarantee proper mating. The cable assembly has a molded strain relief to protect core wires from excessive bending, vibration, and compression. It also includes a built-in EMI/RFI shielded shell that protects against signal interference.

Assembly

The SD-40LP connector is designed with a self-locking coupling mechanism that provides a secure and reliable connection. It can be easily assembled by hand and requires no tools to mate. The threaded coupling nut is designed to self-lock and ensure a secure connection. The connector is also RoHS compliant.

Working Principle

The SD-40LP connector utilizes a reverse bayonet coupling mechanism to achieve a stable connection. The connecting pin is inserted into the socket and then rotated clockwise. The reverse bayonet coupling firmly locks the connector into place, thus providing a secure connection. The connector is also shielded, which helps protect the data signal against any external EMI/EMF interference.

Applications

The SD-40LP connector is an ideal solution for a wide range of applications, such as medical, military/defense, radio communications, transportation, telecommunication, networking, computing, and industrial control. Its superior protection performance and reliability in harsh environmental conditions make it a suitable choice for high power and low profile applications.

The SD-40LP connector is designed to provide reliable performance in a variety of tough and hazardous environments. Its low-profile, lightweight, and highly efficient design, combined with outstanding features, makes it a perfect choice for applications that demand high-performance and reliability.
