Position Sensors High Temperature Hermetically Sealed Switches
Series
FEATURES Enclosure seal: Sealed MILS-8805, enclosure design Symbol Terminal strength: lbs. (66,7N) Strength actuating means: lbs. (156N) Strength mounting bushing: lbs. (1,7Nm) Vibration: .060 (1,52mm) D.A. Shock: .006 sec. sawtooth pulse Also meets moisture resistance, explosion, salt spray requirements. Temperature range: 85°F +600°F 65°C +315°C) Modifications: Receptacle termination available. Temperature rating lowered because receptacle limitations customer-specified leadwire.
Watertight test applicable MIL-S-8805.
GENERAL INFORMATION switches combine maximum sealing, high (600°F, 315°C) temperature capabilities, rugged, heavy duty, corrosionresistant construction provide reliable switching most demanding applications. MOUNTING Plunger actuator switches bushing mount through inch (19,1mm) diameter holes. Lock washer, keying washer, wire lock hexagon mounting nuts lock switches their mounting.
ELECTRICAL RATING MS24594-1 ratings apply when MIL-S-8805/41 invoked.
