PHD Series PLK Modular Pneumatic Pin Clamp Review: Specs, Price and Applications
The PHD Series PLK is a modular pneumatic pin clamp combining high clamping force with a lightweight body, often used as a robot end effector. A completely enclosed pin and long-life seals resist dirt and water in shop air.
It offers more pin diameters than the previous design and three pin styles, and senses pin open or closed position with an AC or DC weld-field-immune switch in a protected housing. A built-in locking system is included.
Quick Verdict
A purpose-built pin clamp for weld areas that locates and clamps a panel through a hole in one compact unit.

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.
A pin clamp inserts a pin into a locating hole in the panel and then clamps with fingers, locating and holding with one device. Weld-field-immune switches keep sensing reliable near resistance welding.
Integration and Selection
Choose pin diameter and style for hole size, mount on fixtures or robot tooling and wire sensors.
Protect from spatter where possible.
