Rectangular connectors offer an array of positioning options and applications to interconnect and isolate circuits. Headers with male pins, like the EJH-125-01-S-D-SM-21-K, come in various forms to make this possible, allowing for anything from simple connection of two wires in parallel, or a complex arrangement for two- or three-dimensional connections in higher power applications. Let’s take a look at the application fields and working principles of this type of connector and header.
Application Field
The EJH-125-01-S-D-SM-21-K is a double row header specifically geared to perform better than most micro-PVC headers in terms of reliability, amount of space taken up, and current capacity, making it great for industrial applications like industrial controllers, automotive, computer systems, robot controllers, and other board-to-board stacking applications.
In many of these applications, features such as EJH’s double-sleeving technology with its adjustable strain relief help ensure longer cable life and improved industrial system connectivity and reliability. The EJH connector also offers a high degree ofprotection from, physical strain from the environment, corrosion or vibration for better durability and greater circuit integrity.
Working Principle of EJH-125-01-S-D-SM-21-K
The EJH-125-01-S-D-SM-21-K is a single-ended header that has a range of current-level options: 10 amps, 20 amps, 30 amps and 40 amps. These high current levels are enabled by its double-sleeved screw technology, which combines the secureness of a screw with the convenience of a sleeve. The double-sleeved screw technology permits current to flow through the contact surface, creating more reliable connections while allowing for repeatable tight contact.
The double-sleeved screws are soldered to the board using lead-free, halogen-free solder, and then tested with a current value of 100% of the rated current level. This allows EJH connectors to remain stable under extremely high current levels without any loss of signal integrity. Additionally, the connector is rated for an operating temperature range of -40°C to +105°C.
The EJH-125-01-S-D-SM-21-K is a great choice for any application where reliable connectivity is a must. Its double-sleeved technology combined with its current-level options makes it perfect for a wide range of industrial applications. This terminal block header is ideal for any application where reliability and long-term durability are key requirements.
