EGZ-6-5 Festo Cartridge Cylinder

Technical Overview

The Festo EGZ-6-5 is a compact, single-acting cartridge cylinder designed for pushing operations. It features a 6 mm piston diameter and a 5 mm stroke length, constructed with a nickel-plated brass housing and a high-alloy steel piston rod for durability. This pneumatic actuator is suitable for environments with moderate corrosion stress (CRC 2) and operates within a temperature range of -20 to 80 °C.

Industrial Applications

1. Automated Life-Cycle Testing for Consumer Electronics Buttons

Used in quality assurance rigs to simulate repeated finger presses on smartphone side-buttons, remote controls, or medical device interfaces. The cylinder is mounted in a dense array to test multiple devices simultaneously.

Problem Solved

Replaces manual testing with a high-speed, consistent mechanical actuation that mimics human finger pressure (approx. 1.4 kgf) without applying excessive force that could damage delicate micro-switches.

2. Microfluidic Chip Clamping in IVD (In-Vitro Diagnostic) Analyzers

Integrated directly into the manifold block of Point-of-Care (POC) medical devices to securely hold disposable microfluidic chips or slides against optical sensors during analysis.

Problem Solved

Provides a precise, low-force clamping action that ensures a proper seal for optical reading without cracking fragile glass/plastic chips, utilizing the compact screw-in cartridge design to save valuable internal instrument space.

3. PCB Datum Banking in Optical Inspection Machines

Acts as a lateral pusher in Automated Optical Inspection (AOI) conveyors to gently nudge small Printed Circuit Boards (PCBs) against a hard stop (datum) for precise alignment before the camera captures images.

Problem Solved

Eliminates positional errors in vision systems by ensuring repeatable board placement. The single-acting spring return ensures the path is automatically cleared for the next board in case of air failure.
