| Lamb Industries M3-Series Pressure/Snap Action Switch | ||
  03
|
||
 |
The M3-Series pressure switch features adjustable calibration, high electrical ratings (up to 16(4)A 250V), and is suitable for operating in vacuum and medium pressure range (between 30 and 2500 mbar) and with different fluids such as gas, air, and liquids. This is due to the separation of the electrical and pressure circuits. Hysteresis can be 10%-30% of the set point. The M4-Series is a higher temperature version. Lower amperage, lower cost pressure switches are available in the P1-Series and 79-Series. |
