Harsh environments switch / waterproof
max. 5 mA | 6600 series Haydon Kerk Motion Solutions

6600 Series switch is designed for harsh environments where long life hermetic seal integrity of the switch is critical. The 130,000 cycle minimum hermetic life of the switch equates to life of aircraft reliability for many applications.

The rugged design and construction incorporates a metal bellows to insure durability of the actuation mechanism. The switch housing is backfilled with inert Nitrogen gas and sealed. Hermetic sealing is maintained per category 5 of MIL-PRF-8805 i.e. 1x10-8 atm cc/sec. The corrosion resistant housing withstands most media and allows exposure of the switch to fluids such as synthetic hydraulic oils and jet fuels.

The switch has been designed to operate below 5 mA at 28 VDC in temperatures as high as 400° F. By changing contact material the switch can be configured for 5 Amp operation.
