EHT-125-01-S-D-SM-04-P Application Field and Working Principle

Rectangular Connectors - Headers, Male Pins are widely used in a variety of electrical and electronic applications. The most common use for these connectors is for signal transmission in high-speed systems. The EHT series of Male Pin Connectors from Hirose Electric Co is one of the most popular models.The EHT-125-01-S-D-SM-04-P is a high-density male pin connector which is regularly used for PCB to cable connections. It has a 2.5mm contact pitch and a 1mm contact height. The connector is made from a single layer of UL 94V-0 polycarbonate material, which gives it good strength and low electrical leakage characteristics. It has a maximum rated current of 0.5V and the contacts have a high retention force, which makes them a reliable choice for signal transmission in fast-paced environments.The connector has an innovative design which offers contact protection and easy mounting. It features a plastic shell with a secure snap-lock closure and polarisation. This ensures that the pins will make a good connection and prevents contact arcing. Additionally, the pins are arranged in an angle to the shell, which ensures an easier cable installation.The connector is UL approved for safety and it has an operating temperature range of -55 to 125 °C. This makes it suitable for use in a variety of environments.The working principle of the EHT-125-01-S-D-SM-04-P is based on the principles of electrical resistance. When an electrical current passes through a conductor, a voltage is developed which is proportional to the resistance of the conductor. This resistance is determined by the material of the conductor and its characteristics such as shape, size, and thickness. The contact pins in the connector are made from copper with a thickness of 0.2mm allowing it to have a low electrical resistance. The pins in the connector are arranged in an alternating pattern so that there is an even distribution of electrical current throughout the connector. This reduces the amount of voltage loss and ensures a good signal transmission. Additionally, the contact force between the mating parts increases with an increase in the current, preventing them from separating. This makes the connection secure and reliable.The EHT-125-01-S-D-SM-04-P is a versatile Male Pin Connector which is widely used in a variety of electrical and electronic applications. Its innovative design, high contact retention force, and UL approval make it an ideal choice for signal transmission in high-speed systems.
