Main Applications and Working Principle of SQW-149-01-L-D Rectangular Connector

The SQW-149-01-L-D is an off-the-shelf two-piece crimptype rectangular connector designed to provide reliable performance in a reliable, economical way. In the signal and power application fields, it is utilized with both commercial, pre-wired interconnects as well as a solid connector system. This two-piece connector family is ideal for a wide variety of applications including wire-to-wire, wire-to-board, and board-to-board connections. The SQW-149-01-L-D rectangular connector is comprised of two components－a receptacle and a header－ which when combined, form a secure interconnect. The receptacle’s design includes individual signal and signal/ground contacts; it also has snap-in mounting demounting actuators for use with PCB’s. The header looks like a plug, and the receptacle is installed on the PCB. SQW-149-01-L-D rectangular connectors offer a higher density solution, and the two-piece connector system enables the user to create numerous termination and contact configurations in relatively small board space. The design provides an interconnect solution that is highly reliable with a low contact resistance. The header employs a 4.2 mm by 6.5 mm rectangular form factor that is capable of transferring power, in addition to control and signal up to 16A (AC/DC). The robust construction of the connections provides a secure connection with the necessary contact retention force to exceed the system vibration and shock requirements. The receptacle’s double layer construction plastic molding ensures high insulation between the contacts, and the header is designed with a insulation base for additional protection against electric shock and short circuits. Additionally, the connector features a wire-to-wire double locking position tapping mode. Also, a keying bar ensures that the mated connectors are the correct size. The SQW-149-01-L-D is designed for Environmental Resistant and Flame Retardant materials, which meets the highest environmental standards. It is important to note that the SQW-149-01-L-D is designed for easy, error-free assembly. The two-piece design enables customers to easily assemble the mating connectors to build a one-connector system. The headers and receptacles can be easily assembled in seconds after assembly, and no additional tools are required. The solder tail type contacts of the header and receptacle enable flush connection to the PCB, providing for a very low profile. In conclusion, the SQW-149-01-L-D rectangular connector is ideal for a wide variety of applications and provides an interconnect solution that is highly reliable with a low contact resistance. It is easy to assemble, has a secure connection, and a high insulation between the contacts. These features make it an ideal choice for signal and power applications.
