KSSB - SWITCH BOX

with optical indicator

Features

This device is particularly suitable for monitoring the position of each valve, even at long distances.
It is manufactured according to VDI/VDE 3845 standards.
It can contain two signalling limit switches either mechanical “SPDT”, or proximity ones.
The limit switch working cams cannot possibly slide since their regulation is granted by a splined shaft, without any need of fixing screws.
Prewiring is carried out by means of numbered terminal: n° 6 for the 2 microswitches, n° 8 for eventually prewiring of the solenoid valve.
There is plenty of room to facilitate all wiring procedures, on installation.
On special request we can provide you with: electric-mechanical microswitches SPTD with gold contacts; cylindrical, slot or V3 (in NAMUR, NPN or PNP executions) inductive limit switches, N.O or N.C. pneumatic limit switches; microswitches for security applications
(NAMUR certificated EEx ia IIC T6).
Explosion-proof type EEx d IIc T5 is also available.
