MK15-B-2

The MK15-B-2 is a specific model of reed switch manufactured by Standex-Meder Electronics, a company known for its expertise in magnetic sensors and components. This particular reed switch is designed for various applications, including automation, security systems, and industrial equipment.

Detailed Description:

1. Construction: The MK15-B-2 reed switch consists of two ferromagnetic contacts enclosed within a glass tube. The contacts are typically made of a nickel-iron alloy, which provides excellent magnetic sensitivity and durability. The glass envelope is hermetically sealed, ensuring protection against environmental factors such as dust, moisture, and corrosive elements.

2. Dimensions: The MK15-B-2 is compact, with a length of approximately 15 mm and a diameter of around 2.5 mm. This small size makes it suitable for integration into tight spaces within electronic devices and systems.

3. Operating Principle: The switch operates based on the principle of magnetism. When a magnetic field is applied, the contacts inside the glass tube come together, completing an electrical circuit. When the magnetic field is removed, the contacts separate, breaking the circuit. This on/off functionality is ideal for applications requiring reliable switching without physical contact.

4. Electrical Characteristics: The MK15-B-2 is designed to handle a specific voltage and current rating, typically around 100V and 0.5A, making it suitable for low-power applications. The switch has a low contact resistance, ensuring minimal power loss during operation.

5. Sensitivity: This reed switch is characterized by its high sensitivity to magnetic fields, allowing it to operate effectively with small magnets. This feature is particularly beneficial in applications where space is limited, and a compact magnetic actuator is required.

6. Applications: The MK15-B-2 is widely used in various fields, including:

• Security Systems: As part of door and window sensors to detect unauthorized access.
• Home Automation: In smart home devices for monitoring and control.
• Industrial Equipment: For position sensing and limit switches in machinery.
• Consumer Electronics: In devices like appliances and toys where magnetic actuation is needed.

7. Environmental Considerations: The MK15-B-2 is designed to operate in a range of environmental conditions, with a temperature rating typically between -40°C to +85°C. This makes it suitable for both indoor and outdoor applications.

8. Mounting Options: The switch can be mounted in various ways, including through-hole or surface mount configurations, depending on the specific design requirements of the application.

In summary, the MK15-B-2 from Standex-Meder Electronics is a versatile and reliable reed switch that combines compact size, high sensitivity, and robust construction, making it an ideal choice for a wide range of electronic applications.
