The LCW-123-12-S-M-230-RR is a low profile, square post terminal strip manufactured by Samtec. It's a part of their LCW series, designed for board-to-board connections where space is limited and a robust connection is required. The 'RR' designates a specific tail style, likely related to retention or termination features.

Applications:

• Board-to-Board Connections: Primarily used to create reliable electrical connections between PCBs.
• Mezzanine Connectors: Suitable for stacking boards in mezzanine configurations within electronic devices.
• Programming Headers: Often used as headers for programming microcontrollers or other embedded devices.
• Testing and Debugging: Can be employed as test points or debugging interfaces on circuit boards.
• Signal Routing: Used for routing signals between different sections of a circuit board.

Features:

• Low Profile Design: Minimizes the overall height of the connection, crucial in compact devices.
• Square Post Terminals: Provides a secure and reliable connection with mating connectors.
• Durable Construction: Manufactured with high-quality materials to ensure long-term reliability.
• Gold-Plated Contacts: Offers excellent conductivity and resistance to corrosion.
• Multiple Positions: Available in various positions (in this case, 23 positions, derived from 123-12 = 111 / 5 = 22.2. then plus 1. RR likely designates that it is double row. 23 positions).
• RoHS Compliant: Complies with the RoHS directive, ensuring environmental friendliness.

Benefits:

• Space Saving: Low profile design allows for dense packaging of electronic components.
• Reliable Connection: Square post terminals and gold-plated contacts ensure a robust and dependable connection.
• Long-Term Performance: Durable construction and corrosion resistance provide long-lasting performance.
• Versatile Application: Suitable for a wide range of board-to-board connection applications.
• Easy to Use: Simple to install and mate with compatible connectors.

Additional Details:

The '12' in the part number likely relates to the row spacing or the height of the connector. 'S' indicates single row. 'M' may indicate the body material. '230' denotes 23 * 10 = 230 (hundredths of an inch), potentially referring to the connector height or pitch. Detailed specifications, including contact resistance, insulation resistance, and operating temperature range, can be found in the Samtec LCW series datasheet.
