The SICK DOL-1208-G02MAC1 is a Sensor-actuator connector cable for industrial control and automation applications.

SICK DOL-1208-G02MAC1 is a sensor-actuator connector cable that solves a common field problem: routing incremental or SSI encoder signals from a machine-mounted sensor to a control cabinet across a vibrating, washdown-prone skid. The cable combines an M12 8-pin straight female connector with 2 m of shielded PUR cable and bare flying leads, so technicians can land conductors directly on terminal blocks without an intermediate junction box.

Because the cable is shielded and uses 0.25 mm² conductors, it supports clean signal transmission in electrically noisy process areas. Its PUR jacket is halogen-free and black, and the connector body is TPU with a nickel-plated brass locking nut. These material choices make the assembly a rugged, field-proven option for mission-critical encoder runs where a loose or intermittent connection would stop production.

What does the DOL-1208-G02MAC1 cable do in an encoder circuit?

In a typical installation, the M12 female head mates with an encoder or sensor outlet, while the flying leads terminate in a control cabinet or drive. The 8-pin layout carries the incremental or SSI signal pairs, and the shield drains electrical interference away from those conductors. With a 2 A current loading rating, the cable is suited to low-power sensor and encoder circuits rather than motor power.

The 2 m length is defined per ordering code, which helps planners match cable runs to enclosure layouts. Because the second head is bare wire, there is no second connector to work loose in high-vibration service. That simplicity is one reason this assembly is dependable in demanding environments.

Key specifications for harsh oil and gas environments

• Operating temperature: −25 °C ... +80 °C for flexible use and the head, covering hot process areas and cold outdoor skids.
• Protection rating: IP67 when mated, supporting washdown and dust exposure common on oil and gas equipment.
• Rated current: 2 A current loading for sensor and encoder circuits.
• Contacts: 8 pins in an M12 straight female connector.
• Conductor specification: 4 × 2 × 0.25 mm² with shielding for signal integrity.
• Cable length: 2 m per ordering code.
• Cable jacket: PUR, halogen-free, black, with a 7 mm cable diameter.
• Connector materials: TPU body and CuZn nickel-plated brass locking nut, tightening torque 0.5 N·m.
• Bending radius: Flexible use greater than 10 × cable diameter; stationary position greater than 5 × cable diameter.
• Bending cycles: More than 2,000,000.

The combination of a wide operating temperature window and IP67 sealing means the cable can remain installed through seasonal temperature swings and routine washdowns. In addition, the high bending-cycle rating points to a design that tolerates repeated flexing on moving machine parts. Note that supply voltage and weight are not available in the source data; refer to the official SICK datasheet for those values.

How does the shielded PUR construction support reliability?

Shielding is the first line of defense against electrical noise from nearby drives and power cables. Because the conductors are arranged as 4 × 2 × 0.25 mm², the cable provides paired signal paths that help preserve encoder pulse quality. The PUR jacket resists abrasion and remains flexible at low temperatures, which matters on outdoor wellhead or pipeline skids.

In addition, the nickel-plated brass locking nut provides a durable metal-to-metal interface at the M12 connection point. A tightening torque of 0.5 N·m gives technicians a defined target for secure mating without overstressing the connector. These details are why the assembly is built for demanding environments.

Installation and integration guidance

Route the cable so that the bend radius stays within the stated limits: greater than 10 × cable diameter in flexible use and greater than 5 × cable diameter in stationary positions. Because the cable is shielded, terminate the shield at the cabinet end according to the panel builder's grounding practice. The M12 female connector should be mated to a compatible 8-pin male outlet and tightened to 0.5 N·m.

When wiring into a fieldbus or drive network, confirm gateway and cable compatibility with the supplier. PetroPartsOnline can provide application-specific selection guidance for encoder interfaces and cable routing. Contact PetroPartsOnline for parts suited to your application's requirements.
