On the marketDC contactor 24There are various forms, styles, and techniques. Based on your application, only one type of relay may be suitable. In other cases, multiple types of relays may be suitable. By understanding the advantages and disadvantages of different relays, you should be able to choose the relay for your current job.
Although many of the conclusions in this article apply to all DC contactor 24 applications, it specifically discusses the factors that should be considered when using different types of relays on switch modules for automatic test equipment (ATE) applications. The comparison made here is between relays with similar voltage, current, and power ratings, whose form factors can be found in typical switch modules.
The common types of relays used in ATE applications are:
Electromechanical relay
Dry spring relay
Solid state relay
Field-effect transistor switch
FET switches provide a fast, low-cost solution, but are limited to operating at low voltages.
直流接触器24It may be a widely used relay in ATE applications today. They are composed of coils, armature mechanisms, and electrical contacts. After the coil is energized, the induced magnetic field will move the armature, thereby opening or closing the contacts.The mechanical lifespan of electromechanical relays is usually shorter than other types of relays. The advancement of technology has increased their mechanical lifespan, but electromechanical relays still do not have as many actuators as comparable reed relays.
The contacts on DC contactor 24 are often larger and more robust than some other relay types. Larger contacts enable them to withstand unexpected surge currents caused by parasitic capacitance present in circuits, cables, etc. Unfortunately, larger contacts require larger packaging sizes, so they cannot be densely placed on the switch module.
