The NKE CHP304A-100 is a pneumatic air chuck (also referred to as a pneumatic gripper or cylinder) manufactured by NKE Corporation, a Japanese company specializing in factory automation components, including parts handling equipment like air chucks for industrial applications. These devices are typically used in manufacturing and assembly lines for gripping, clamping, or handling workpieces with compressed air actuation.
Key Specifications and Features
Based on product listings and manufacturer details for similar models in the CHP series (e.g., CHP304A-50 and CHP230 series), the CHP304A-100 likely includes:
- Type: Double-acting pneumatic cylinder with sliding table mechanism.
- Stroke/Size: 100 mm (indicated by the “-100” suffix, common in NKE nomenclature for stroke length).
- Operation: Powered by compressed air; suitable for precise positioning and gripping.
- Accessories: Often bundled with NSV (proximity or travel) sensors operating at 10-30V DC for position feedback.
- Build: Compact design with parallel jaws for large gripping force and opening allowance; available in multiple sizes.
- Applications: Ideal for automation in automotive, electronics, and general manufacturing for handling small to medium parts. It supports high repeatability and durability in high-cycle environments.
