Non-Rotating Rod / Double Acting, Single Rod CQ2K Series Specifications

Small Auto Switches Can Be Installed on 4 Surfaces

Remodeled with a new body for more flexibility.
Depending on the installation conditions, auto switches can be mounted on any of the 4 surfaces. (ø12 to ø25 [12‑ to 25‑mm bore size]: Mountable on 2 surfaces) This improves flexibility of equipment design.

ø32 to ø63 (32‑ to 63‑mm bore size)

ø12 to ø25 (12‑ to 25‑mm bore size)

Rounded Slots for Mounting Small Auto Switches Available on 4 Surfaces

No Projection of Auto Switch

Prevents damage to auto switch.
Sleeves cannot get caught in the auto switch and its mounting rail, improving ease of work and safety.
Reduction in labor hours for design.
The outer dimensions of the cylinder do not change when an auto switch is mounted, so there is no need to check for interference with machinery.
