A narrow 1-mm-pitch, board-to-wire connector developed by Hirose Electric features a positive locking mechanism located at its center that provides a clear, tactile click sensation regardless of the number of repetitive cycles. The latch prevents both uneven locking commonly attributed to side locks and incomplete mating. The DF50 connector’s distinct audible click, which confirms that the mating sequence is secure, can be beneficial when dealing with high-vibration and other critical applications. Its structure maintains a cable pull force of 10N minimum to prevent contacts from pulling loose during installation. Current rating is 1 A per pin, voltage rating is 100 V ac/dc, contact resistance measures 50 mΩ maximum at 20 mV (1 mA), and operating temperature ranges from −35 to 85°C. The connector is designed with blade-type contacts attached to a thick housing wall that’s resistant to cracking or deformation. Applications include LCDs, LCD TVs, PDPs, wireless LANs, notebooks/laptops, industrial control, and others.
