These connectors are engineered for a current rating of 0.5 A AC, DC for AWG #32 wires and 0.2 A AC, DC for AWG #36, with a voltage rating of 30 V DC. They operate within a temperature range of -25℃ to +85℃, ensuring reliability under various environmental conditions. The SUR series is characterized by a 3-point grip construction that allows for the use of super fine wires and includes a shrouded header with a twin U-slot insulation displacement section for secure and efficient wire connections. The connectors are available in a wide range of circuit sizes from 2 to 22, catering to diverse application requirements. They are made from copper alloy contacts with tin plating and a housing of PA, UL94V-0, ensuring compliance with RoHS standards for environmental safety. The series is available in both natural and lemon yellow color options, with model numbers specifying the number of circuits, wire range, and color. For instance, model numbers such as 02SUR-32S or 02SUR-36L indicate a 2-circuit connector suitable for AWG #32 and AWG #36 wires, respectively, with 'S' denoting natural color and 'L' lemon yellow. The connectors are supplied on embossed tape for automated assembly processes, highlighting JST's commitment to providing components that meet the needs of modern, high-efficiency manufacturing environments.
