- "F3S, F3A AND F3C" SERIES ADJUSTABLE DIAPHRAGM PRESSURE SWITCHES
F3S adjustable pressure switches activate a micro-switch once a preset pressure value is reached.
The pressure is set by rotating the external screw located at the center of the instrument clockwise to increase and counter-clockwise to decrease the value. Mechanical stops protect both the spring and the micro-switch from over pressurization.
Type F3S: exchange electrical contacts
Type F3A: normally open electrical contact
Type F3C: normally closed electrical contact
Technical Features:
Anodized aluminum body.
Installation Position: it can be mounted in any position.
Working temperature: from -20°C to + 80°C
Switching frequency: 120 cycles/min.
Switching accuracy: within 3% of set pressure
Fixed hysteresis value:
F3S type: about 7% of set value
F3A and F3C: about 4% of set value
Weight: 0.1 Kg.
Electric Features:
Electrical connection: fast-on 6.3mm
Electrical protection according to DIN 40050: IP54.
