A401 Capteur de pression d'air différentiel négatif 20 ~ 150 Pa

Air Pressure Sensing Switch Description

The A401 air pressure sensing switch is a single pole single throw normally open type switch with 2 forward terminals, which have 187#(4.8*0.5mm) and 250#(6.3*0.8mm) for your options. Kindly remind that the size of the terminals and direction is for the application to connect easily, if you have another requirement please feel free to contact us or visit our air pressure switch page to check.

Because of the patented design of the A4 series, we can control the pressure switch in a very small differential force, which is 10Pa which is smaller than most of the pressure switches on the market.

This air pressure sensing switch is the negative type whose working pressure range is from 20pa to 150pa and its set ON and set OFF pressure is available for customization. Meanwhile, the positive pressure type is also available. Besides, it also has a wide working temperature range(-40 to 110 ℃) so that it can reduce the effect of weather.

Generally, the A401 air pressure sensing switch can be used in the wall-hanging boiler furnace, gas water heater, HVAC system product, VAC system product, and so on. What’s more, if you need the electrical type air pressure sensors, please visit our product page.
