3/2-way limit valve, roller lever NC/NO, G 1/8", nominal width 4 mm, 320 l/min, anodised aluminium

The 3/2-way limit valve detects the end positions of pneumatic cylinders, slides and workpiece carriers without any electrical components. The approaching machine axis runs over the roller lever, which then opens or closes an air path with a nominal width of 4 mm. An actuating force of only 17 N at 6 bar is required, so even light movements are reliably registered. A flow rate of 320 l/min is enough to feed downstream control valves and small actuators directly. The anodised aluminium body with G 1/8" ports stays compact enough for tight fixtures.

Advantages

• Responds from an actuating force of 17 N at 6 bar
• Nominal width of 4 mm and 320 l/min for direct control of small actuators
• NC/NO version, the pressure inlet can be placed at any port
• Body in anodised aluminium, internal parts in brass, stainless steel and aluminium
• Operating pressure of 0 to 12 bar across a temperature range of -10 to +70 °C
• NBR seals for lubricated and non-lubricated, filtered compressed air

Applications

• Purely pneumatic end position sensing on cylinders in packaging and assembly lines
• Sequence control on clamping and drilling fixtures where 320 l/min is sufficient to switch on
• Presence checking of workpieces in feeders and magazines
• Cycle control of small handling axes with low approach forces
