Omron Electronic Components LLC has released a series of 0.4mm pitch SMD board-to-FPC connector. The XB4A plug and XB4B socket may be used in low-profile end products such as PDAs, notebook computers, mobile phones, digital cameras, MP3 players, GPS devices, handheld test and measurement instruments, and voice recorders.

Available in 40-pin and 80-pin versions, XB4A and XB4B's twist-resistant design allows for the connectors to be unmated in any direction. Rated current is 0.3A AC/DC and rated voltage is 50V AC/DC with a contact resistance of 60m maximum (at 20mV DC max., 100mA max.). Insulation resistance is 1,000m (min.) at 250Vac. Insertion force is 1.7N maximum per pin with removal force of 0.1N min. per pin, and they can be mated and unmated 50 times.

When mated, the plug and socket have a stacking height of 0.9mm (0.035 inch) and a width of 4.1mm (0.161 inch) or 5mm (0.20 inch) including the solder terminals. The XB4A and XB4B connectors' high reliability double-contact point, gold-plated contacts are said to be extremely resistant to improper contact alignment. There is a nickel barrier between the contacts and PCB terminals that prevents solder creepage, said Omron.

The plug and socket mate easily with carefully molded guides that lead the housing to the exact mating position. When mated properly, there is an audible, tactile click to confirm that the connection is fully seated and also enables a high-retention force, making them resistant to shock and vibration. The housing is designed to keep contacts from being damaged while insulating them from the board to increase board design efficiency.

The XB4A and XB4B are RoHS-compliant and meet the requirements for reflow profiling using lead-free solder. They are also packaged in tape and reel.

MSRP for the XB4A-4035-D (40-pin plug) and XB4B-4035-D (40-pin socket) series is about 30 cents each in quantities of 1,000, while the XB4A-8035-D (80-pin plug) and XB4B-8035-D (80-pin socket) series is about 50 cents each in 1,000pc quantities.

Delivery is stock to eight weeks.
