This small, versatile connector offers excellent mechanical strength and a wide range of electrical features which make it suitable for multiple use-cases.

Application Field

The 55102-G17-03 is an incredibly useful tool in a variety of applications such as:

• Commercial Electronics
• Automotive and Transportation
• Industrial Control
• Test and Measurement
• Computer and Networking
• Telecommunications

The 55102-G17-03 is appropriate for use in both indoor and outdoor applications such as dust-proof, water-resistant, and temperature critical operations due to its excellent weatherproofing and corrosion-resistant properties. It is also well-suited for a variety of power, signal, and high-speed interfaces.

Working Principle

The 55102-G17-03 is a fully molded flat cable and board-to-board connector system that is composed of two interconnected mating parts and a hood that is part of the female connector. The primary locking mechanism that prevents accidental disengagement of the connector is the hooded cover. When the connector is engaged, the hood is pushed up and compresses the two halves of the envelope together for a secure connection.

The 55102-G17-03 utilizes a 0.050” (1.27 mm) pitch, 5-row configuration for easy placement and alignment when mating. The system also utilizes two keying features located near the sides of the header to ensure that the system is mated only once. Contact retention into the female connector utilizes a keyed cantilever design which allows for secure retention and easy insertion, while the contact tolerance is maintained as the contacts are inserted.

When the male and female connectors of the 55102-G17-03 are mated, the contact between the two is established via a snap-in locking mechanism. This snap-in locking also allows the contacts to be securely maintained during aggressive shock and vibration conditions. The 55102-G17-03 is also offered with a optional sealed version that provides superior protection from dust and other environmental contaminants.

Conclusion

The 55102-G17-03 is a reliable electrical connector with wide range of applications, providing secure connections with excellent mechanical and electrical characteristics. Its 0.050” (1.27 mm) pitch and 5-row configuration makes it ideal for board-to-board and cable-to-board connection, while its two keying features ensure a secure and accurate mating. With its optional sealed version, the 55102-G17-03 can be used in harsh environments and provide an extra level of protection in addition to its excellent snap-in locking mechanism.
