Since the technology sector is known for its high costs in the use of energy and electricity, it is important to take into account the degree of energy efficiency of the components used. In this sense, bistable solenoids are devices capable of maintaining two stable positions without continuous energy consumption, a condition that benefits the company that will acquire them.
How do bistable solenoids work?
When the electromagnet is deactivated, it maintains two stable working positions, which eliminate the need for constant energy to maintain a specific position. One position is held by a permanent magnet system and the other by a return spring, making them especially suitable in power-constrained environments where the use of high-performance linear electromagnets might not be feasible.
Features and advantages of using bistable solenoids
Bistable electromagnets, such as our ERB series, are ideal for environments where locking and unlocking positions need to be maintained for extended periods of time.
Energy efficiency
Bistable solenoid only require energy during state transitions, which is why they require less current for operation than electromagnets that are constantly energized.
This is highly recommended in application where power consumption is limited such as in electrical distribution application and trains and trams.
Stable positioning
As mentioned above, bistable electromagnets can maintain their stable position without continuous electrical power. Once activated in a particular state, they remain in that state until another electrical stimulus is applied to change position. This is a particularly beneficial feature for applications where power consumption and position retention are critical issues.
EMI reduction
Bistable electromagnets also excel in their ability to reduce electromagnetic interference (EMI). By operating with intermittent energy pulses instead of a constant current flow, these devices generate less interference compared to other devices.
ERB bistable electromagnets also offer customized solutions, making them an efficient and reliable option for situations that require locking and unlocking positions to be maintained for extended periods. This system allows remote resetting by a simple reverse polarity pulse. Their design and operation provide significant energy savings and ensure high reliability, making them a preferred choice in many industrial and commercial sectors.
