Rectangular Connectors - Headers, Receptacles, Female Sockets are an essential component of electronic devices and are used as a medium to connect multiple components together. In this article we will explore the 68685-336LF, a Rectangular Connector used for electrical and electronic applications, and understand its working principle and applications.

68685-336LF Overview

The 68685-336LF rectangular connector, manufactured by MOLEX, is a .050” (1.27mm) pitch compact connector designed for high-density, high-durability performance. It houses up to 8 power/signal contacts in a 1.55mm x 5.5mm profile and comes with a dual beam contact and fully isolated terminal walls. The 68685-336LF is strongly resistant to shock and vibration, which makes it ideal for use in harsh environments.

The parts come with gold-plated, tin-plated, and 30μ” gold-plating contact finishes, giving them enhanced corrosion resistance and contact reliability. The connectors are compliant to JEDEC IC, IP67, and UL 1977 specifications.

Working Principle

The 68685-336LF is a pass-through connector, in which the top and bottom halves of the connector are separable. Contacts are inserted into the cavities of the connector, and a locking collar is secured over the contact to hold them in place. The two halves of the connector are then combined to form a complete assembly. The connector is locked together through press-fit contact retention and double locking beams.

The double-beam contacts of the 68685-336LF are designed to provide robust electrical performance in harsh conditions that involve shock, vibration, and temperature stress. The connector’s contact ribs ensure precise insulation spacing and improved contact uniformity. Additionally, the connector is also designed with terminal walls to provide insulation between contacts and reduce crosstalk and cross-rail contact shorting.

Applications

The 68685-336LF connector is mainly used in modular terminals, LCD display boards, and LED lighting systems. Its compact size and shock and vibration resistance make it an ideal choice for these applications.

The connector is also highly reliable in a wide range of temperature conditions, and can be used for applications such as automotive, medical, industrial, and telecommunications.

In telecommunications systems, the 68685-336LF is commonly used for connecting voice and data signals, as well as power supplies. It can also be used in applications that require small form factor, high reliability, and superior electrical performance. Additionally, the connector is also used in LED and LCD display systems, where it connects to power supplies and relays.

Conclusion

The 68685-336LF is a rectangular connector that is designed for high density and high-durability performance. It is well-suited for use in harsh environment applications due to its shock and vibration resistance and insulated contact design. The connector is also compliant to JEDEC IC, UL 1977, and IP67 testing, and is widely used for communications, LED lighting, and LCD display systems.
