Rotary Switches are widely used in all kinds of industrial, commercial, and residential applications. The 51EMB30-01B08S is a versatile, reliable rotary switch option for various applications and is a popular choice for various tasks. This article provides an overview of the 51EMB30-01B08S application field and working principle.

Application Field

The 51EMB30-01B08S is a common choice for a number of applications including:

• Industrial Equipment – Rotary Switches are a common choice for industrial equipment due to their robustness, small size, and variety of configurations. The 51EMB30-01B08S is suitable for a wide range of industrial settings and is particularly useful for applications where multiple, clearly defined settings are required.
• Home Appliances – The 51EMB30-01B08S is also a common choice for home appliances, especially for applications requiring smooth operation, such as setting the temperature on a heating appliance or the settings on a blender. It can be used in all situations where a clearly defined setting requires to be controlled, such as a fan speed setting.
• Communication Systems – Rotary Switches are widely used in communication systems, including for controlling the gain and frequency settings on a radio or for adjusting the size of a cell phone antenna. The 51EMB30-01B08S is an ideal option for these types of applications as its small size and low-contact arcing characteristics make it perfect for use in limited system space.

Working Principle

The 51EMB30-01B08S operates on the principle of a rotary cam switch. It has a rotary shaft which is connected to the stationary contactor. As the shaft rotates, it moves the contactor along a line of detent positions, which activate different sets of contacts in the switch.

The 51EMB30-01B08S consists of two separate contact plates which hold two sets of contacts. As the shaft rotates, the top plate moves along a line of detent positions and passes a conical contact at each point. The lower plate is stationary and contains the terminals for the various switch contacts. As the top plate passes each detent position, it activates a separate set of contacts.

The 51EMB30-01B08S is designed to be highly reliable and has a low contact arcing time of 0.25ms or less. This makes it suitable for applications where malfunctioning or slow operation due to arcing of the contacts could be an issue. It is also highly resistant to shock and vibration, making it extremely reliable and suitable for use in high vibration environments.

As an added benefit, the 51EMB30-01B08S also has a very low profile and small size, making it suitable for use in constrained environments. This makes it ideal for applications where a large, bulky rotary switch is not necessary or not possible.

Conclusion

The 51EMB30-01B08S is a robust, reliable rotary switch option for various applications. It is suitable for industrial equipment, home appliances, and communication systems and can be used in applications requiring multiple, clearly defined settings. It is designed to be highly reliable and has a low contact arcing time of 0.25ms or less, making it suitable for applications where malfunctioning could be an issue.

The 51EMB30-01B08S is an ideal choice for applications requiring a small, low profile rotary switch, with reliable, long-lasting performance. As such, it is an excellent choice for a wide range of applications.
