Industrial Applications

1. Automotive Paint Shop CPX Terminal Upgrades

In automotive vehicle painting facilities, pneumatic valve islands (like the Festo CPX modular electrical terminal) drive the automation. The Festo AK-8KL cover is installed directly over the CPX-AB-8-KL-4POL electrical connection blocks to protect the sensitive AS-Interface and sensor I/O wiring from environmental contaminants while strictly adhering to paint-shop material regulations.

Problem Solved

Standard IP20 connection blocks are vulnerable to dust and moisture, and using non-compliant plastics in paint zones outgasses silicones that cause paint-wetting defects (craters). This cover upgrades the block to an IP65/IP67 rating to withstand washdowns without introducing any paint-wetting impairment substances.

2. Food & Beverage Packaging Washdown Protection

Automated bottling and secondary packaging lines utilize CPX modular electrical terminals for pneumatic control and sensor integration. The AK-8KL cover is deployed over the terminal strips of the manifold block, tightly sealing the electrical connections from water and cleaning agents during routine plant sanitation.

Problem Solved

Exposed 4-pin terminal strips will short-circuit and corrode when subjected to industrial liquid washdowns. The AK-8KL cover serves as an IP65/IP67 extension, completely shielding the electrical connections from low-pressure water jets and temporary immersion, while its moderate corrosion resistance prevents degradation from mild cleaning agents.

3. Pharmaceutical Powder Dosing Equipment Sealing

Pneumatic control manifolds in pharmaceutical cleanrooms or active powder dosing stations must remain completely sealed against particulate matter. The compact Festo AK-8KL cover is fitted to CPX I/O modules to prevent active pharmaceutical ingredient (API) powders from entering the electrical terminations.

Problem Solved

Fine powder ingress into standard unsealed I/O blocks causes electrical communication failures and unacceptable contamination risks. The IP67-rated cover provides absolute dust-tight protection, and its RoHS-compliant construction guarantees that no restricted hazardous heavy metals compromise the pharmaceutical manufacturing environment.
