Dublin's SpindleShield technology quickly alerts machine operators to abnormal leaks inside the coolant union attached to coolant-through spindles, preventing serious damage to the spindle before it occurs. The Dublin 1103-WLSB Wireless Leak Sensor Box combines the leak sensor system with SpindleShield technology. When an abnormal leak occurs within the coolant union, the detection unit sends a wireless signal to the alarm unit, immediately notifying the operator with an LED light and buzzer. *To utilize this system, a separate Dublin SpindleShield series coolant union is required.

The SRG-type slip ring is compatible with all industrial real-time protocols and can transmit Ethernet signals of up to 1Gbps. It can be used alone or in combination with rotary joints to send various fluids to the rotating part. To improve EMI protection performance, all exterior components of the SRG are made of metal and are electrically connected. In recent years, industrial field networks have been advancing in communication speed, and communication standards with a speed of 1Gbps have begun to spread widely. In Dublin, we have developed slip rings that can accommodate high-speed field networks that require such 1Gbps. For gigabit Ethernet connections, you can choose between X-coded M12 connectors and shielded RJ45 connectors. *Please refer to the basic information for detailed usage conditions.
