Switching principle
- 4-point contact
- Self-cleaning contacts
- Integrated air-pressure compensation system (constant switching pressure under all environmental conditions)
Signaling
- 12 individually configurable LED displays (high-end version): PK21, PK22, PK23, PK28, PK41 and PK-Z
- 4 LED displays (economy version): PK25, PK26, PK27 and PK29
- Luminous colors red, green
- Orientation, confirmation or warning tones (individually parameterized)
- Orientation tone and confirmation tone as continuous or intermittent tones max. 52 dB(A), depending on the installation
