Pressure connections :2 plastic pipe connection pieces (P1 and P2), external
diameter 6.0 mm:
P1 for connection to higher pressure (marked +)
P2 for connection to lower pressure (marked –)
Medium :Air, non-combustible and non-aggressive gases.

Model No.Adjustment range for upper switching pressure from toSwitching differential set toTolerance for upper and lower   switching pressure
Switching pressure specifications apply to vertical installation
which is also the recommended position with pressure-pipe
connections pointing downwards. If the switches are installed
horizontally with AMP connection terminals uppermost, the
switching values are approx. 20 Pa higher.
