EJH-125-01-F-D-SM-48-P connectors are rectangular headers, male pins commonly used in electronics, intended for mounting on printed circuit boards (PCBs). Generally, these components have two or more male pins housed in a rectangular body with a pin insertion depth of 1mm and a nominal voltage rating of 1000V. The header is designed with a stepped version on each side to ensure adequate clearances between mating connectors.

The EJH-125-01-F-D-SM-48-P connector is designed for connecting HSSP (high speed serial port) circuit boards together. The connector\'s male pins are designed to contact the female contacts on the keystone-style mating circuit board. The stepped design of the connector allows the male pins to contact the female contacts on the other side without being hindered by the other board\'s connectors. The connector body is made of machinable PBT polyester (polybutylene terephthalate) metalized with low-resistance nickel, which increases its capability to handle high-frequency signals.

The EJH-125-01-F-D-SM-48-P connector is designed to reduce EMI (electromagnetic interference) and provides a secure connection between components. It features a footprint of 0.4mm between pins, which minimizes inter-pin capacitance and crosstalk. Additionally, the connector\'s bottom half is equipped with a molded-in strain relief feature, which helps reduce cable stress and flexing, and provides shielding for the connector\'s external components. EJH-125-01-F-D-SM-48-P connectors have a power rating of 1.4A, and a maximum voltage rating of 60VDC.

The working principle of EJH-125-01-F-D-SM-48-P connectors is quite simple. When connecting two boards together, the male pins of the connector are inserted into the female contacts on the mating circuit board. The proper orientation of the pins is ensured by the keystone placement of the contacts. The pins are then mechanically secured in place by the latching mechanism provided by the connector body. This latching mechanism ensures a secure connection while also providing the flexibility of disconnecting the two boards when necessary.

EJH-125-01-F-D-SM-48-P connectors are used in a wide variety of electronics projects ranging from circuit boards used in medical equipment, consumer electronics, and high-end communication equipment. Additionally, these connectors can be used in applications where high-speed data transmission and shielding are essential to the success of the project, such as automotive electronics, telecom switching equipment, and internet routers.

In conclusion, EJH-125-01-F-D-SM-48-P connectors are a reliable, cost-effective solution for connecting two HSSP circuit boards together. The small footprint and stepped design ensure that the connector will fit into tight spaces, while the latching mechanism ensures a secure connection. The connectors\' low voltage and power ratings also make them an ideal choice for a variety of applications.
