Value for money - Information on DC contactors

The SR75-2 solid-state relay uses power FET switches to prevent overload and short-circuit currents. The short-circuit protection function not only provides protection when a short circuit or overload occurs when the relay is turned on, but also provides protection when the relay switches to a short circuit. It is equipped with a 16 pin immersion package through a through-hole or surface mount.

We offer a wide range of capabilities to design and manufacture relays andThe DC contactorWhen you need commercial off the shelf products or components that must meet strict military specifications, or even highly specialized, custom designed products, we can help you meet your requirements.

For military applications that require stronger and higher quality parts, DC contactorsWe have long provided high-performance products for use by all branches of the US military. These MSSRs are designed to meet the requirements of MIL-PRF-28750 and have undergone thorough screening and testing to ensure they can function effectively on site.

We provide various solutions for high reliability and space environmentsThe DC contactorSolution. Our aerospace products were initially designed according to established QPL and MIL standardsRelays manufactured according to specifications are then customized based on the specific application needs of customers. Clean room construction, highly controlled processes, tracking and serialization of data, quality audits throughout the entire production cycle, and extensive product testing.Our DC relay has a single wire coil wound around the iron core to manufacture the electromagnet. When the coil is energized, the magnetic properties generated are stable because the current is continuous. Once the current is cut off, the iron core is no longer magnetized, and the spring-loaded lever will return to a relaxed position, with its contacts switching back to their original position.A unipolar relay is a single circuit contact arrangement that represents a connection at one position or another common state. Industrial relays are used in production lines, robots, elevators, control panels, CNC machine tools, motion control systems, lighting, building systems, solar energy, HVAC, and a range of safety critical equipment.

Our DC contactors are designed specifically for aerospace and defense applications, with a rated on/off current of 500 amperes and an overload rating of up to 2000 amperes. We offer DC contactors with electronic or mechanical retainers, or we can provide basic contactors that you can use with your own circuit.

Our high-voltage switchgear portfolio also includes lightweight, compact, and AC/DC contactors for use in aerospace, commercial, and military power systems. theseThe DC contactorThere are multiple contact configurations, current/voltage ratings, auxiliary contact configurations, and installation methods. We provide technical experience, knowledge, and capabilities to help customers meet demanding requirements.

Our HARTMANAC and DC contactors are lightweight and environmentally friendly (with gaskets) sealed. The sealed casing can be used in certain harsh environmental conditions or at altitudes above 50000 feet. Provide multiple main contact configurations and auxiliary contact configurations. The design of AC and DC contactors should meet the applicable requirements of MILPRF-6106 and/or specific customer specifications.
