The number of pins in these connectors has increased along with the greater role of electronic control in automobiles. In addition, this non-waterproof, high-density type connector fulfills the need for a small and lightweight product.

[Features]
[High-density implementation achieved with a large number of pins]
· These composite-type connectors include both signal (2.2 A) and power (5.7 A) internal circuits in the same connectors. These four-row type connectors are small, highly dense, and include a large number of pins with a 2.2 mm contact pitch (for signals), 3.2 mm contact pitch (for power), and up to a maximum of 135-pin connectors. Multiple socket connectors are combined together on the wire side for each single pin header on the circuit board side.
[Mechanical lock structure ensures secure fitting]
· The mechanical lock structure protects against vibrations and pulling. A distinct click sound helps confirm that secure fitting has occurred.
[Double locking structure reliably prevents loss of contact]
· Contact with the socket housing is maintained via a housing lance and an internal retainer contained in the housing. This double locking structure, which locks at two locations, reliably prevents loss of contact due to vibration or pulling.
· The retainer's structure ensures that a contact cannot be set into the locking position unless it is completely inserted. This makes it possible to detect partial insertion of contacts.
[Low insertion force structure with easy insertion and extraction]
· A low insertion force type structure requiring 70 N or less of force per socket housing to achieve insertion makes insertion and extraction easy.
[Tin and gold plating are available for the contact finish]
· The standard finish for contacts is tin plating. Gold plating is also available for 135-pin pin headers, offering a higher level of contact reliability.
[Misconfiguration-prevention types also available]
· Pin headers (70-pin and 135-pin versions) and socket housings come in standard types as well as types with different mating part conformations in order to prevent incorrect configuration. Use of these types prevents incorrect fitting when two different pin headers with pins in the same positions are used next to each other.
· Crimping enables easy connection.
