Clamping locator AMWFH-S series

pneumatic

Overview
This light‑duty pneumatic locator module (model AMWFH‑S) is designed for Flex locating systems to provide high‑precision positioning and rapid fixture plate changeover. It is a single‑acting pull‑down clamp that uses air only for unclamping; spring force maintains clamping when air is removed. Repeatability is 0.06 mm and the unit requires only 44 psi for operation.

Product variants

• AMWFH49‑S (ID 230414) — Ø49 mm overall diameter; clamping force 134 lbs; compatible with pins AMWFH49‑M6L, AMWFH49‑M6S; SKU AMWFH49‑S.
• AMWFH64‑S (ID 230417) — Ø64 mm overall diameter; clamping force 224 lbs; compatible with pins AMWFH64‑M8L, AMWFH64‑M8S; SKU AMWFH64‑S.

Technical specifications

• Model: AMWFH‑S (pneumatic Flex clamping locator — light duty, pull‑down)
• Accuracy (repeatability): 0.06 mm
• Operation: Single‑acting — air used only for unclamping; spring provides clamping when air is removed
• Unclamping: Two unclamping ports

Applications

• Mounted to a base plate in Flex locating systems for fast fixture plate changeover
• Precision positioning and repeatable clamping in machining and assembly operations
• Ideal where spring‑to‑clamp behaviour is required (fail‑safe clamping on loss of air)
