Rectangular connectors, such as the 68021-128HLF, are commonly used for low power wire-to-board, board-to-board, and system-level interconnects. This type of connector is available in a variety of styles, including headers, male pins, and specialist configurations. Here, the focus is on the 68021-128HLF, an 8-way shrouded header with 2.54 mm pitch and a locking latch.

Applications

As a multi-row connector, the 68021-128HLF is an ideal solution for a wide range of applications, including those that require Board-to-PCB, Board-to-Board, System-Level and Wire-to-Board connectivity. It’s also suitable for low power, small space and lightweight applications.

Features

The 68021-128HLF is made from UL94V-0 rated materials, with a gold-plated Phosphor Bronze contact and a high temperature UL94V-0 thermoplastic insulator. The housing is also made from a high temperature thermoplastic, which provides resistance to temperature extremes and extremes in humidity. The connector has a self-retaining latch, which gives extra protection to the connection. It also has a slide locking mechanism, which prevents accidental disconnection.

The 68021-128HLF is perfect for low voltage and high current applications, as it is designed to provide superior electrical performance. It has an operating voltage of up to 100V, an operating temperature range of -40ºC to +105ºC and an insulation resistance of 5000MΩ at 500V. The contact resistance is 10mΩ max., and the dielectric strength is 500V/μs.

Working Principle

The 68021-128HLF connector uses a slide locking mechanism and a self-retaining latch for secure connection. When inserted, the clip engages with the latch and the pin locks into place. The locking latch provides extra protection to the connection and helps to prevent accidental disconnection. The pins are also shrouded to protect them from dust and debris.

The 68021-128HLF is designed for reliable performance and easy installation. It has a keyway along the front of the connector, which helps to align and guide the connector into its mating part. This reduces the chance of the pins getting bent or damaged during installation. The connector also has a low profile design, which makes it ideal for space-constrained applications.

Conclusion

The 68021-128HLF is a rugged, reliable connector suitable for a wide range of applications. It features a robust design, with a lockable latch and shrouded pins for extra protection. The connector is also easy to install and offers superior electrical performance. It operates at up to 100V and has an insulation resistance of 5000MΩ at 500V, making it ideal for low voltage and high current applications.
