DOL-1208-G20MAC1: Field-Proven Encoder Connectivity for Demanding Environments

Industrial automation has evolved from simple relay logic to complex, networked control systems. As plants grew more sophisticated, the demand for reliable signal transmission became mission-critical. The SICK DOL-1208-G20MAC1 sensor-actuator connector cable addresses this need with a 20 m shielded PUR construction and an 8-pin M12 female connector. It is engineered to deliver dependable performance in rugged oil and gas environments.

Key Features and Technical Specifications

• Connector A: Female M12, 8-pin, straight design for secure mating.
• Connector B: Flying leads (bare wires) for flexible termination.
• Cable Length: 20 m, as specified by the ordering code.
• Conductor Specification: 4 × 2 × 0.25 mm² cross-section.
• Shielding: Shielded construction to protect signal integrity.
• Operating Temperature: −25 °C ... +80 °C for flexible use and head.
• Protection Rating: IP67 when mated properly.
• Rated Current: 2 A current loading capacity.
• Bending Radius: Flexible use > 10 × cable diameter; stationary > 5 × cable diameter.
• Bending Cycles: > 2,000,000 for long service life.

The combination of a shielded PUR jacket and high bending cycles makes this cable suitable for continuous flexing applications. The halogen-free PUR material resists oils and coolants, while the nickel-plated brass locking nut ensures a stable connection.

Applications in Oil & Gas and Industrial Automation

In oil and gas facilities, sensors and actuators often operate in harsh conditions. This unit is designed for incremental and SSI encoder signals, making it ideal for position feedback on valves, motors, and other rotating equipment. Its 20 m length allows for flexible routing in large skids or remote monitoring points. The IP67 rating ensures protection against dust and water ingress, while the wide temperature range supports reliable operation in both cold and hot environments. Whether on a drilling rig or in a processing plant, this cable delivers the reliability you can depend on.

Installation and Maintenance Guidance

Proper installation is key to maximizing cable life. Observe the bending radius: for flexible use, keep bends greater than 10 times the cable diameter; for stationary runs, greater than 5 times. The 0.5 N·m tightening torque on the M12 connector ensures a secure, vibration-resistant connection. When wiring the flying leads, follow the encoder manufacturer's instructions. Periodic inspection of the cable jacket and connectors helps prevent unexpected downtime. Because the cable is shielded, ensure proper grounding at the flying lead end to maintain signal integrity.
