Valve actuator position switch 3AT

smallhermeticharsh environments

KLIXON® 3AT Series high temperature hermetic switches are snap-action devices that provide the reliable switching action in extremely harsh environments. These switches have a temperature range of -65 °F to +600 °F (-53.9 °C to +315 °C) and while switching 1 Amp resistive at 30VDC. Sensata has over 100 different switch packages in single and multi-pole configurations with actuation styles such as leaf, lever, pushbutton, plunger, roller, and toggle. KLIXON® 3AT Series switches provide indication of position in many different aerospace and defense applications. Typical applications include thrust reverse actuation systems as well as high temperature aircraft valves like fuel, engine start, fuel, environmental control system, anti-icing, bleed air, and avionics cooling valves. Features Qualified per MIL-PRF-8805, Enclosure Symbol 5 Hermetically sealed with dry nitrogen gas backfill Proven snap-action switching, reliable performance and long life Excellent shock and vibration resistance Switching up to 4 amps Optimal for low level circuits Temperature range between -275°F and 450°F Small, lightweight axis–symmetric design for robustness and reliability Single and multiple pole designs available Various mounting configurations for custom applications Sealed and unsealed plunger options Wide range of side plate designs for narrow width applications PMA Approvals for various commercial aircraft Customer approvals for space and military applications
