Rectangular Connectors - Headers, Male Pins

The 57202-G52-09ALF is a rectangular connector specifically designed for use when extra space and polarization is needed at the mating interface in a number of applications.

Application Field

57202-G52-09ALF square connectors provide reliable and robust pluggable connectivity solution for a wide range of demanding applications. They feature two rows of uniquely spaced square shaped male pins in a male to female form-factor. This feature makes them ideal for connections that require secure connections in tight spaces. Typical applications for these connectors include industry computer equipment, medical equipment, communications systems, and other electrical and electronic components.

Connector Working Principle

The 57202-G52-09ALF\'s unique pin spacing and square shape provides a secure and reliable connection that\'s impossible to mix-up when mating. Unlike traditional circular connectors, each pin is a uniquely shaped male pin that prevents the pins from rotating and mating at an incorrect angle. The square shape also sparks a secure locking which ensures that the inserted pins won\'t come loose and the connection won\'t malfunction.

57202-G52-09ALF rectangular connectors are rated to 28V/2A, and use a nickel-plated brass or stainless steel construction resistant to corrosion and wear. The resin casting provides excellent electrical insulation and additional protection against shock and vibration, making it an ideal choice for tough applications. The mating faces of the connectors are keyed to prevent misalignment when mating and provide secure connections.

Standard Pin Assignments

The 57202-G52-09ALF rectangular connector features two distinct mating rows of 9 pins in an alternate configuration. This allows for two different communication signals to mate in the same connector. The standard pin arrangement facilitates efficient signal transmission and helps eliminates time-consuming electrical interference in applications. For example, the 9 pins are arranged in an alternating signal and power pin pattern which allows for 13W of power depending upon the cable gauge used. This helps reduced the time needed to manually identify the signal and power pins and simplifies mating processes.

Conclusion

The 57202-G52-09ALF rectangular connector is a versatile solution for a wide variety of demanding applications. It provides reliable and secure connections thanks to its unique square shape and mating pin arrangement, and is rated for up to 28V/2A. Its distinct pin assignment pairs power and signal transmissions in the same connector, and ensures that connections won\'t malfunction and pins won\'t come loose. These features make it an ideal solution for efficient connection you need for your most demanding applications.
