The S7 (MIL-DTL-83527) series electrical connector is a rectangular modular medium-to-large rack and panel connector primarily used in lightweight, replaceable units (RUs) within avionics bays. It provides reliable signal and power connections for avionics systems, ensuring proper operation during flight.
The S7 (MIL-DTL-83527) series connectors support a variety of contact technologies, including signal, power, coaxial, triax, quadrax, and fiber optic, to meet diverse signal transmission requirements and enable high-speed data transmission, making them suitable for systems requiring high transmission rates. The S7 (MIL-DTL-83527) series connectors feature an optional EMI shielding ring, providing maximum EMI/RFI protection, ensuring stable and reliable signal transmission in complex electromagnetic environments and minimizing the impact of EMI on signal quality. Designed for extreme environmental conditions, the S7 series connectors operate within a wide temperature range of -65°C to 155°C and offer excellent shock, vibration, and moisture resistance, ensuring reliable operation in harsh aerospace and military environments.
