KSIF ATEX aluminium with optical indicator

TECHNICAL FEATURES
- Made to easily verify the visual and electrical position of each valve even from long distances.
- Built according to VDI / VDE 3845 standards. (EN15714-3)
- It can contain two limit switches either mechanical "SPDT" or proximity.
- The cam of limit switch cannot slide since their regulation or other tools.
- The pre-wiring is realized means of numbered terminals: n° 6 for the two microswitches, and extra poles for eventual solenoid wiring (see wiring diagrams).
- N. 2 threaded electrical connections for cable gland
- Operating temperature:
from -40°C to + 80°C (standard);
from -25°C to +80°C for limit switch code "24", "60" and "70".
- Protection rate: IP 67
