Description

Uses: High electrical rating, for 250V.

Main applications: Vacuum detection on pumps, filters, ventilation, and electrical appliances.

Membranes: EPDM, dia 22 mm. Silicone or NBR on request. Double membrane on request.

Fluid: water or air

Fitting: Plastic or metal

Pressure: negative (Vacuum)

Housing: PA66, UL94 VO

Contact: SPDT, snap action. NO or NC contacts available with MOQ

Electrical rating: Depends on micro-switch operating force that is linked to the electrical rating

• Standard rating micro-switch (medium and high vacuum calibration only): 16A 125/250VAC;1/2HP 125VAC; 3/4HP Differential about 60 mbar
• High rating micro-switch (medium and high vacuum calibra- tion only): 2HP 240V, 21(8) A 240V (UL, CSA VDE switch). Dif- ferential about 90
• Low force micro-switch (vacuum less than minus 150 mbar): 1/4HP 6(1) A 240V ( UL, CSA VDE switch) Differential about 40
• On request: up to 25A 250V

Action: momentary.

Set point calibration: factory calibrated and sealed, not field adjustable

Calibration condition: the contact between Com and NC opens when vacuum pressure goes from atmospheric pres- sure to requested vacuum set point.

Set point calibration limits: from minus 50 to minus 700 mbar

Electrical connection: 6.35 x 0.8 mm quick connect terminals

Maximum pressure: 4 bars (58 PSI)

Maximum vacuum: minus 700 mbar (relative pressure)

Ambient temperature limits: 0 to 85°C
