LEMO-compatible connectors in the 00B, 0B, 1B, 2B, 3B, and 4B series are push-pull connectors known for their reliability, ease of use, and robust design. These connectors are widely used in industries requiring high-performance connections with 360-degree EMC shielding and a range of contact configurations. Here's an overview of these connectors:

Overview of LEMO-Compatible B-Series Connectors:

1. Series Designations:

   • 00B Series: Smallest size, often used for compact devices, typically with fewer contacts (2-4).
   • 0B Series: Slightly larger, with more contact options (up to around 8 contacts), used in applications requiring more connectivity in a small form factor.
   • 1B Series: Offers a middle ground in size and contact count, suitable for a wide range of applications.
   • 2B, 3B, 4B Series: Progressively larger sizes, supporting higher pin counts (up to 32 contacts), used in applications requiring robust multi-signal connections.

2. Push-Pull Mechanism:

   • Secure Locking: The push-pull mechanism provides a quick, secure connection with a simple push to connect and pull to disconnect, ensuring that the connector stays locked in place during use.
   • Vibration Resistance: The design is highly resistant to vibration and accidental disconnection, making it suitable for dynamic environments.

3. 360-Degree EMC Shielding:

   • Comprehensive EMI Protection: These connectors offer full 360-degree EMC shielding, ensuring that all electrical connections are protected from external electromagnetic interference.
   • Signal Integrity: The shielding ensures high-quality signal transmission, even in environments with significant electrical noise.

4. Contact Configurations:

   • 2 to 32 Contacts: The connectors are available with various pin configurations, ranging from 2 to 32 contacts, accommodating both simple and complex signal, power, and data transmission needs.
   • Gold-Plated Contacts: Contacts are typically gold-plated for enhanced conductivity, corrosion resistance, and long-term reliability.

5. Metal Shell:

   • Robust Construction: The metal shell provides excellent mechanical protection and contributes to the connector's overall EMC performance.
   • Variety of Finishes: Available in different finishes (e.g., chrome, black chrome) depending on the application requirements and aesthetic preferences.

6. Environmental Protection:

   • Sealing Options: These connectors are often available with sealing options to meet IP50, IP67, or IP68 ratings, providing varying levels of protection against dust and moisture.

Applications:

• Medical Devices: Used in medical equipment where reliable, shielded connections are critical, such as in imaging systems, patient monitoring, and diagnostic devices.
• Broadcasting: Ideal for audio, video, and data connections in professional broadcasting equipment, where signal integrity is paramount.
• Military and Aerospace: Suitable for use in communication systems, avionics, and other demanding environments where durability and EMI protection are essential.
• Industrial Automation: Used in control systems, robotics, and machinery where multiple signals need to be reliably transmitted in electrically noisy environments.
• Test and Measurement: Commonly used in equipment requiring precise signal transmission and reliable connections.

Compatible Manufacturers:

1. REDEL (by LEMO): Offers high-quality push-pull connectors that are fully compatible with the B-Series, often used in medical and other high-tech applications.
2. Fischer Connectors: Provides robust alternatives to LEMO B-Series, offering similar performance and compatibility.
3. ODU: Known for producing compatible connectors with push-pull locking mechanisms, suitable for demanding applications.
4. Amphenol: Offers LEMO-compatible push-pull connectors with a focus on industrial and military applications.

Considerations for Selection:

• Pin Configuration: Choose the number of contacts based on the specific requirements of your application (e.g., signal, power, data).
• EMC Requirements: Ensure that the level of EMC shielding meets the demands of your operating environment, particularly if you are in a high-EMI area.
• Environmental Sealing: Select the appropriate IP rating if your application involves exposure to dust, moisture, or other environmental factors.
• Size Constraints: Consider the size of the connector (from 00B to 4B) based on the space available and the number of contacts needed.
