The DPSN1 is a pressure switch with a built-in digital display from the AirTAC DPS series. It has two NPN switching outputs and reads pressure directly on a dual-row LCD. It is used to monitor air pressure and vacuum in pneumatic circuits, such as cylinder supply lines and vacuum cup lines on SMT equipment.
Choose the pressure range
The range is set by the first code after the series name.
| Model code | Pressure range | Proof pressure | Use it when |
|---|---|---|---|
| DPSN1-01… | −100 to 100 kPa | 200 kPa | You monitor vacuum, or low positive pressure up to 100 kPa |
| DPSN1-10… | −100 to 1000 kPa | 1500 kPa | You monitor vacuum and also normal shop-air pressure up to 1000 kPa |
Both ranges include vacuum down to −100 kPa. If your line runs at normal shop-air pressure (about 500 to 700 kPa), choose a model with code 10 (−100 to 1000 kPa), because code 01 stops at 100 kPa.
The last digits of the model code are the cable length (for example, 020 is 2 m, 030 is 3 m and 050 is 5 m), according to distributor listings. State the length you need when you ask for a quote.

Mounting
Mounting accessories are ordered separately and are not included with the switch. When you ask for a quote, tell us how you plan to mount it (panel or line side) so we can include the right accessory.
