UNITRONIC® BUS ASI (G) 2X1.5 GY – Fieldbus Cable Introduction

The UNITRONIC® BUS ASI (G) 2X1.5 GY is a bus cable with a flat design and a 2-core structure (2X1.5 mm²), specially developed for AS-Interface systems. It is designed for fixed installations in industrial environments. The cable features a rubber outer sheath in grey (RAL 7001) and is halogen-free, making it suitable for use in safety-critical areas where corrosive gas emissions must be avoided.

Cable Applications

Suitable for fixed installation and occasional flexing without tensile stress

Usable in dry and damp environments

Designed for medium mechanical stress applications

Ideal for use at the field level to connect sensors and actuators

Specifically engineered for data and signal transmission in AS-Interface systems

Cable Benefits

Available in three outer sheath materials: Rubber, TPE, and PVC

The “G” version is halogen-free

The TPE version is oil-resistant and ideal for wet areas with water-based cooling lubricants

Features Reverse Polarity Protection through geometrically coded cable design

The yellow cable is designed for simultaneous data and power transmission with separate cores, reducing wiring effort

The black cable supplies auxiliary power at 30 V DC; the red version is suitable for 230 V AC and heavy current; the grey version supplies 48 V DC

The “LD” (Long Distance) version allows module connection at extended distances and reduces the need for additional AS-i power supplies

Versions with the suffix “A” are UL certified and suitable for North American markets
