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 applications where knowing the status of the poppet's position is important.

Position Switch Features:
  • PNP — solid-state switch with normally open and normally closed outputs
  • IP65 rated, 4-pin, M12 connector
  • CE-approved switch
  • Factory set for position indication
  • 20–30-Vdc operating voltage
Logic Element Features:
  • 5000-psi (350-bar) pressure rating at all ports
  • Bidirectional flow capacity
  • Four functional options
