Technical Specifications
Detailed engineering parameters based on manufacturer documentation
| Parameter | Value | Parameter | Value |
|---|---|---|---|
Note | To prevent damaging the gold layer, 30 VDC switching voltages and 50 mA currents must not be exceeded. Higher switching power eventually evaporates the gold layer. The resulting deposits in the housing may reduce service life. | Dielectric strength (control/load circuit) (AC, 1?min) | 5?kVrms |
