A good choice for automated clamping, these retractors use compressed air to extend and retract a locating pin, protecting the pin from damage in applications where fixtures move through a process, such as along a conveyor belt.

Set the tang in a slot below the work surface to prevent thin material from sliding underneath the face.

Sealed at the top to prevent debris from getting inside and making them seize up, these guide pins are a good choice for machining fixtures.

Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with ¼"-20 holes.
