M Series Pin Clamp Cylinder (CKQ/CLKQ)

Caution
- See the catalog for specification details.
- Product images may be representative images. Refer to the manufacturer's catalog for shape details.
Product Description
The clamping position height can be selected according to the workpiece.
[Features]
· Possible to mount on 4 surfaces, and 2 auto switches on the same surface, for improved flexibility of system design.
· Protrusion of auto switch shortened by 5 mm.
· For improved workability, direct mounting is possible, no mounting hardware required.
· 55 types of guide pins.
· Fine adjustment of the clamping height is possible by selecting the type with shims.
· Optional locking mechanism can be selected.
· The D-P4DW auto switch is also mountable.
· 2 switches can be mounted on the same surface.
