SN236 series feedthroughs

Eaton's SN236 series of fire-resistant high-power feedthrough is ideal for engine and APU (auxiliary power unit) applications and can withstand harsh environmental conditions. Our design incorporates ceramic insulators to prevent the spread of fire (resistance to 1100°C / 2012°F during 15 minutes) and demonstrate  high temperature resistance (up to 200°C / 392°F) and pressure resistance (leak rate <10-6 atm.cm3/s at 1 bar pressure difference). The SN236 latest version - SN236HTFWC - is qualified according to DO160 index G. This unique feature for a power firewall connector can significantly facilitate your equipment qualification.

SN236 connectors are ideally suited to withstand harsh environmental conditions. They can typically be found on wing and cabin junctions, as well as pylon and engine junctions.
