Miniature pressure switches

for tough applications

Ashcroft

The Ashcroft A-Series miniature watertight pressure switches are designed for tough applications where conventional designs often don't measure up. A rugged 316 SS enclosure gives uncompromising protection. Materials of construction have been selected for long life. Precision snap acting micro switches are featured and fully encased to prevent moisture from corroding switch contacts. The switch, depending on range, is either an all welded 316 stainless steel diaphragm sealed piston design or a direct acting piston design sealed with a Buna-N or Viton O-ring. the device is suitable for pressure alarm, shutdown, or control on heavy vehicles, machine tools, electronic equipment, engines, compressors, food and beverage processing equipment, and wherever size is a consideration or equipment is being downsized. It is suited for pressure ranges from vacuum to 520bar and can beoperated in a wide temperature range (-40 to 100°C).
