Phoenix Contact 1824544

The MSTBU 2,5/21-ST-5,08-FL is designed for direct mounting applications, supporting a nominal current of 12 A and a rated voltage of 320 V. Its 21 positions are arranged with a pitch of 5.08 mm, allowing for efficient space utilization on printed circuit boards.

Constructed from a green PA housing, this connector meets stringent flammability ratings, achieving V0 per UL 94 standards and ensuring safety in various environments. The contact material, a copper alloy, is hot-dip tin-plated, providing excellent conductivity while adhering to WEEE/RoHS compliance, making it free from whiskers as per IEC standards.

For connection, it employs a screw connection with a tension sleeve, accommodating a range of conductor cross sections from 0.2 mm² to 2.5 mm² for both solid and flexible conductors. The connector is designed to handle a stripping length of 7 mm and operates effectively under a torque range of 0.5 Nm to 0.6 Nm. Notably, it is crucial to comply with IEC 61984 standards, ensuring that the connector is neither plugged nor unplugged under voltage or load.

With a height of 17 mm (excluding solder pins), the connector is packaged in cardboard with 50 pieces per package, facilitating easy handling and storage.
