Compact electronic pressure switches / vacuum switches Series SWMN and SWMS
Ports: G1/8, M5 thread or Ø 4, 6 mm plug-in tube
Measuring range: 0 ÷ -1 bar, 0 ÷ 1 bar with analog output,
0 ÷ -1 bar, 0 ÷ 6 bar with digital PNP output
Measuring range: 0 ÷ -1 bar, 0 ÷ 1 bar with analog output,
0 ÷ -1 bar, 0 ÷ 6 bar with digital PNP output
The Series SWMN and SWMS vacuum/ pressure switches can be installed directly at the measuring point or pressure/ vacuum determination point in handling systems, thanks to its highly compact dimensions.
Its reduced weight (only 50 grams with a 2 meter cable) and robust construction allow its installation on applications with high accelerations.
The four types of connection enable a high flexibility and an easy installation inside machines or pneumatic cabinets.

Coding Example
| SWMN | – | AP | – | T | – | 2 |
| SWMN | SERIES SWMN SWMS | |
| AP | OUTPUT SIGNAL (SWMN) AV = Analog output signal – vacuum AP = Analog output signal – pressure PN = PNP output – vacuum PP = PNP output – pressure | OUTPUT SIGNAL (SWMS) NO = Normally Open NC = Normally Closed |
| T | TYPE OF CONNECTION T = Ø6 tube U = Ø4 tube (only for SWMN) G = G1/8 thread M = M5 thread | |
| 2 | ELECTRIC CONNECTION 2 = Cable of 2 meters M = M8 3 pin connector |
