349580 Bürkert: Industrial Connectivity for Smart Valves
The 349580 is a specialized M12 Connection Cable designed for the high-reliability interlinking of Bürkert valve terminals and sensors. In the era of Smart Factories and Industry 4.0, the integrity of the data and power signal is as critical as the fluid control itself. This cable features a molded M12 connector with high IP-rating protection, ensuring that signals are transmitted without interference in environments where electromagnetic noise (EMI) from motors and drives is prevalent. It is commonly used with the Bürkert Type 8640 or Type 8644 valve islands, facilitating rapid installation and modular expansion.
Detailed Technical Characteristics
- Connector Type: M12 (A-coded).
- Cable Length: Check version (typically 2m, 5m, or 10m).
- Number of Poles: 4-pin or 5-pin (Standard configuration).
- Protection Rating: IP67 (Dust and immersion resistant).
- Jacket Material: PUR (Polyurethane) – Oil and abrasion resistant.
- Shielding: Fully shielded to prevent EMI.
Integration & Troubleshooting
Lifecycle State: Active. Diagnosis: Intermittent communication errors or «Fieldbus Fault» LEDs on a valve island are often caused by damaged cables. Check the 349580 jacket for cuts or sharp bends that could compromise the internal twisted pairs. Installation Advice: Use the M12 knurled nut to hand-tighten the connector. Avoid using pliers, as this can damage the internal O-ring and lead to moisture ingress. Compatibility: While designed for Bürkert systems, this cable follows standard M12 protocols, making it compatible with Siemens ET200 stations, Festo terminals, and Balluff I/O blocks. Its PUR jacket makes it ideal for use in «drag chain» applications where the cable is in constant motion.

Why PUR over PVC?
We supply the PUR version (349580) because it resists the harsh cooling lubricants found in CNC machining centers, where PVC cables would harden and crack within weeks.
