Introduction

EJH-125-01-S-D-SM-04 is a type of rectangular connector header most frequently used for power, signal and data connections. It is a male pin with a housing that consists of an upper part and a lower part, providing usual protection from the external environment and mechanical constraints.

Application Field

EJH-125-01-S-D-SM-04 is typically used in industrial, automotive and lighting markets. It can be also used in electrical and medical equipment, such as heating systems, white-goods and hospital devices. It is used mainly for transmitting power, data and signal.This type of rectangular connector is made out of brass with nickel plated contacts for increased corrosion-resistance and durability. It is rated for a maximum voltage of 500V, meaning it can handle applications up to 500V without any issue.

Working Principle

The working principle of EJH-125-01-S-D-SM-04 is quite simple and straightforward. The main purpose of the connector is to provide a secure connection between two different contact points. The procedure involves two separate parts, namely the lower and upper parts of the housing. The lower part is the mating part that requires to be snapped into the upper part. The upper part has internal screws which will hold the lower part firmly in place once the two contact points get pinched together. When the lower part is snapped into the upper part, the connection is established. The contacts within the connector are designed in such a way that they can withstand a high level of voltage and amperage without any issues.

Conclusion

In conclusion, EJH-125-01-S-D-SM-04 is a type of rectangular connector typically used in industrial, automotive and lighting markets for transmitting power, data and signal. It is made out of brass with nickel plated contacts and is rated for a maximum voltage of 500V, meaning it can handle applications up to 500V without any issue. The working principle of this connector involves two parts, the lower part is the mating part that requires to be snapped into the upper part. Once the two contact points get pinched together, the connection is established.
