PHD Series PLKD Disappearing Pin Clamp Review: Specs, Price and Applications
The PHD Series PLKD is a pneumatic disappearing pin clamp. Its fully enclosed pin retracts completely, making panel removal easier, and its fingers extend or retract independently of the main pin.
Dual switches report four conditions: pin fully extended, finger in or out, clamped and pin fully retracted. It allows sideways loading and unloading and reduces part damage.
Quick Verdict
A smart evolution of the pin clamp that gets out of the way for sideways part removal.

Design and Operating Principle
In body-shop welding and assembly, parts are located on pins and held by clamps while robots weld or join them. Clamps and pins on fixtures and robot end effectors must survive weld spatter, dirt and constant cycling while holding positions precisely.
When the pin retracts completely below the surface, the finished assembly can slide out sideways instead of being lifted over the pin, simplifying robot or conveyor unloading and preventing scratches.
Integration and Selection
Use the four switch states to sequence clamping and unloading in the PLC.
Design fixtures for sideways part exit.
