Introduction

90309-128LF is an 8 position, 0.100 inch (2.54 mm) pitch rectangular connector - header with male pins, which is available in wide variety of packaging options - from simple bags to tape and reel for higher volume production. It is uses a high retention force design to ensure a positive latching relationship to minimize the effects of vibration and shock resistance and ensure the highest level of reliability in mating. It also has two rows of 4 positions and has proven performance in a variety of applications.

Application Field

90309-128LF is widely used in many kinds of the electronic equipments, such as monitor controllers, audio & video equipment, computers, vending & gaming machines, automotive systems, test & measuring instruments, medical device, communications systems and more.

Feature

90309-128LF provides several key features for many applications, such as:

Mates with 90309-136 wire-mount socket contacts

90309-128LF features four gold-plated phosphor bronze spring-loaded contacts in each row for easy in-line mating with wire-mount socket contacts 90309-136.

High retention force

With a high retention force design, 90309-128LF ensures a positive latching mate with minimal effects of vibration or shock on the connector. Moreover, it has proven performance in a variety of high-reliability applications.

Compact design

90309-128LF features a compact design with a width of only 0.100 inch (2.54 mm) pitch. This allows it to be used where space is limited.

Selective gold or tin plating

90309-128LF is available in either selective gold or tin plating for contact area.

Low contact resistance

It has low contact resistance which guarantees reliable and repeatable electrical performance.

Working Principle

When mated with 90309-136 rectangular socket contact, 90309-128LF will form a durable and robust connection. The contact tongues on the male pins are contained in channels along the sides of the male header, allowing the socket contact to “swing” into the male pin header. These two components then lock into one another with the use of the internal latching mechanism which ensure a secure connection. The latching mechanism helps prevent shock, vibration, and loose connections.

Conclusion

In conclusion, 90309-128LF rectangular connectors - header with male pins is an ideal solution for many applications. It has the features of high retention force, compact design, selective gold or tin plating, and low contact resistance. Moreover, the latching mechanism provides reliability and stability. This connector must be mated with 90309-136 rectangular socket contact for proper operation.
