The MR-20LK2+ is a vertical type plastic case designed for junction applications in the MR series of rectangular connectors. This 20-contact case provides a dual mechanism of screws and spring-locks to withstand shock and vibration in demanding environments. The case features a dust-tight mechanism and is engineered for high-density, compact installations in data terminal equipment, factory automation, communications equipment, and instrumentation systems. With dimensions of 39.3 mm (A) × 18 mm (B) and a cable clamp design, the MR-20LK2+ is compatible with female connectors (MR-20F, MR-20FW, MRP-20F01) and male connectors (MR-20M, MR-20MW, MRP-20M01), making it ideal for applications requiring reliable, space-efficient connector solutions in industrial and commercial equipment.
