HUADA ZMDM-21SQN Micro Rectangular Electrical Connector

The HUADA ZMDM-21SQN Micro Rectangular Electrical Connector is a cutting-edge solution designed for applications requiring compact and reliable electrical connections. This series stands out due to its significantly reduced dimensions compared to the J29A series, being 2.78mm shorter in length, 5.4mm narrower in width, and 3.9mm shorter in height. This reduction in size makes the ZMDM-21SQN approximately 40% of the volume of the J29A, making it an ideal choice for space-constrained environments. Despite its compact size, it boasts impressive performance characteristics, including an operating temperature range from -55°C to +125°C, an insulation resistance of 5000 mΩ, and a mechanical life of 500 cycles. These features ensure that the connector can perform reliably under extreme conditions, making it suitable for a variety of demanding applications.
In addition to its robust performance, the ZMDM-21SQN is engineered to withstand high levels of impact and vibration, with specifications of 490m/s² and 10-2000Hz at 196m/s², respectively. This durability ensures that the connector maintains its integrity and functionality even in harsh environments. The connector also features a low contact resistance of 8 mΩ and a current capacity of 5 A, ensuring efficient electrical performance. Furthermore, it can resist pressures up to 800V and operate effectively in high humidity conditions (40°C, 98%). These attributes make the HUADA ZMDM-21SQN a versatile and reliable choice for industries that demand high performance and compact design in their electrical connectors.
