Electrical selection
The sheet lists DIN 43650 connection, N/C or N/O switching, and maximum switching voltages of 30 V DC or 250 V AC. Confirm load rating and wiring against the model-specific table.
Yuken Gauges and pressure switches
Pressure and differential-pressure switches for electrical monitoring of hydraulic filter condition.

EI-R13-20 and EI-E05-20 use different measurement principles and connections. Select the indicator for the filter type and required alarm function rather than by pressure setting alone.
The alarm setting and maximum operating pressure are different quantities. The catalogue warns that cold, viscous oil may cause a false alarm; assess indication under the specified normal operating conditions.
Use the catalogue alongside the details below, then send the complete model and application requirements for selection support.
| Model | Type | Maximum operating pressure | Thread | Catalogue application |
|---|---|---|---|---|
| EI-R13-20 | Pressure switch | 12 bar | 1/8" BSP | Return and suction filters |
| EI-E05-20 | Differential electrical switch | 420 bar | M20x1.5 | Inline and pressure-line filters |
