Match the switch to the pressure setting
The YSG hydro-electric pressure switch uses a spring-loaded sealed piston to operate a microswitch at the selected hydraulic pressure. Its encapsulated construction protects the mechanism against dirt.
The range uses sub-plate mounting and a plug-in electrical connector. Each model has its own pressure setting range and maximum operating-pressure rating.
Review the switching-pressure differential curve for the selected model when checking the required switching cycle. The differential varies with the pressure setting.
Compare YSG pressure ranges
| Model | Pressure setting range | Maximum operating pressure |
|---|---|---|
| YSG-A-20 | 5 to 40 Kgf/cm² | 40 Kgf/cm² |
| YSG-B-20 | 12 to 100 Kgf/cm² | 100 Kgf/cm² |
| YSG-C-20 | 20 to 200 Kgf/cm² | 200 Kgf/cm² |
| YSG-D-20 | 30 to 350 Kgf/cm² | 350 Kgf/cm² |
The 350 Kgf/cm² rating applies to YSG-D-20. Select the model for both the required switching pressure and the maximum pressure at the switch connection.
Electrical connection and switching
Contact selection
The catalogue shows common, normally open and normally closed microswitch contacts. Use the manufacturer’s connection diagram to match the required action above and below the pressure setting.
Send the supply voltage, load current and control-circuit details for electrical suitability confirmation. Check the connection diagram and the selected switch’s contact rating before wiring.
