3/2-way limit valve NC/NO, cam actuation, G 1/8", 320 l/min, anodised aluminium body

In systems without electrical signal transmission this limit valve handles position sensing with compressed air alone. An approaching cam pushes the plunger and switches the 3/2-way element, which releases up to 320 l/min at a nominal width of 4 mm. The anodised aluminium body is designed for operating pressures from 0 to 12 bar and works between -10 and +70 °C. As the valve is built as NC/NO, the pressure inlet may be connected to either of the two G 1/8" ports, so normally closed and normally open function can be chosen freely.

Advantages

• Purely pneumatic position sensing without electrical parts or auxiliary power
• Flow rate of 320 l/min at a nominal width of 4 mm
• Operating pressure from 0 to 12 bar and temperatures from -10 to +70 °C
• Actuating force of 27 N at 6 bar, matched to cam tracks on slides
• Anodised aluminium body with internal parts in brass, stainless steel and aluminium
• Usable as NC or NO because the pressure inlet may sit on either G 1/8" port

Applications

• End position sensing on pneumatic slides and cylinders by means of a mounted cam
• Fully pneumatic control chains in areas without electrical installation
• Feed and indexing devices operated on a supply of up to 12 bar
• Warm surroundings up to +70 °C, for example at ovens or drying sections
• Workpiece clamps whose clamped position is checked mechanically
