More Options for Logic Elements with Position Indicating Switch

Sun has expanded the logic elements with a position indicating switch.

Logic valves are now offered in four different versions across three different sizes of valves. These valves incorporate an inductive switch to provide confirmation of the poppet position. These valves can be used in critical applications where knowing the status of the poppet's position can offer an added level of safety.

Position Switch Features:

PNP - solid state switch with normally open and normally closed outputs
IP65 rated, 4-pin, M12 connector
CE approved
Factory set for position indication
20-30 VDC operating voltage

Logic Element Features:

5000 psi (350 bar) pressure rating at all ports
Bi-directional flow capacity
Four functional options
