68021-452HLF

The 68021-452HLF is a rectangular connector from the Header-Male Pin range. It is a standard-sized, 2.54 mm-pitched, pin header that is used to interconnect various electrical devices, such as PCBs, printed circuits, electrical switches, sockets, PCB connectors, and other related components. The 68021-452HLF has two main features: dual beam spring tab connectors with a retention force of over 8 pounds, and a polarized face that ensures correct orientation for mating connectors.

The 68021-452HLF is particularly known for its applications in the PCB assembly and prototyping industry. It is commonly used to connect two or more microcontroller boards, power buses, and digital signal processors (DSPs). This makes the connector ideal for prototyping, prototyping systems for DSPs, and for the production of complex printed circuit boards.

The 68021-452HLF features a unique two-piece design that allows it to easily fit into through-hole and SMT (Surface Mount Technology) boards. Its large diameter ensures that there is minimal thermal resistance through the connection. Additionally, the connector supports multiple levels of pin architectures to facilitate multi-channel applications.

The working principle of the 68021-452HLF connector is based on its unique design. The connector is constructed of two primary components: a male-pin header and a retention spring. The male header is designed to connect with holes on a PCB. The retention spring fits around the male header and locks it into place, ensuring that the connection is secure and free from adverse environmental conditions.

In addition to its distinct physical characteristics, the 68021-452HLF connector is also designed to provide reliable electrical connections. The spring-loaded pins ensure that there is low contact resistance. Additionally, the pins are gold-plated to ensure electrical performance and adequate contacts between the pins. This ensures that the connectors are able to provide stable electrical connections in harsh environments.

The 68021-452HLF connector also offers several design advantages over traditional pin headers. Its compact size makes it ideal for high density applications. Additionally, its two-piece construction makes it easy to assemble and is compatible with high speed automatic insertion systems. Its low thermal resistance also helps reduce the chances of a system board overheating.

The 68021-452HLF is a robust and reliable rectangular connector which is suitable for numerous PCB prototyping and assembly applications. Its two piece design, low thermal resistance, and gold-plated contacts make the connector suitable for long-term use in extreme environmental conditions. It is also easy to assemble and is compatible with high-speed automatic insertion systems. Therefore, the 68021-452HLF is a reliable and cost-effective solution for various PCB assembly and prototyping applications.
