It features a 4-row configuration with 2.54 mm pitch and through-hole solder termination. The fully shrouded housing with friction lock provides secure mating with the corresponding MQS receptacle. The tin-plated square pin contacts rated at 7 A per contact make it suitable for automotive power and signal distribution. The PBT glass-filled housing meets UL94 V-0 flammability requirements and is qualified for automotive operating temperatures from -40 to 85 degC.","working_principle":"The 953118-4 operates as a multi-row board-mount header in the MQS connector system. The 40 positions are arranged in 4 rows of 10 positions each on a 2.54 mm grid. The shrouded housing with 4 walls protects the pin contacts from mechanical damage and ensures correct mating orientation. The friction lock mechanism provides audible and tactile confirmation when the mating receptacle is fully engaged. Board guide features assist in alignment during the mating process. The through-hole solder termination provides robust mechanical attachment to the PCB.","pin_description":"
