SICK DOS-1205-G Field Connector

DOS-1205-G is a SICK field-wireable M12 female connector (part no. 6009719): female connector, M12, 5-pin, straight, A-coded. The cable is connected by screw-type terminals, so it can be fitted on site to a cable you cut to length, without a pre-moulded assembly.

What the DOS-1205-G is for and how it is fitted

This connector is the straight version, so the cable continues in line with the sensor axis. It suits sensors with an axial plug and installations where there is room behind the sensor.

Permitted cable diameter 4 mm … 6 mm and cross section ≤ 0.75 mm²; current loading 4 A; shielding: unshielded. Connector material PA, colour black, locking nut CuZn, tightening torque 0.6 Nm, enclosure rating IP67 and head temperature range .

Technical specifications

Type code DOS-1205-G and part number 6009719

The code of a SICK DOS connector gives the series (DOS), the number of poles (5) and a letter for the housing form (G for straight, W for angled in the two versions on this site). The part number 6009719 is the order key. A 4-pin and a 5-pin M12 connector are not interchangeable, and a connector with a different pole count will not match your sensor.

Other active types in the same SICK family, each with its own part number:

• DOS-1205-GQ (part no. 6021353)
• DOS-1205-W (part no. 6009720)
• DOS-1205-GX (part no. 6047950)

• DOS-1205-WX (part no. 6047951)

Wiring and assembly notes

Strip the cable to the lengths shown in the SICK assembly instructions, insert the wires into the screw terminals using the contact numbers, and tighten the nut to 0.6 Nm. The cable diameter must fall inside the 4 mm … 6 mm range for the seal to hold the stated rating. Unshielded connectors do not provide a screen connection, so choose a shielded version where the sensor cable needs it.

Because this connector is wired in the field, it suits cut-to-length runs where a moulded cable would be too long or too short. Match the cable outer diameter and the core cross-section to the limits in the data sheet, confirm the five-pin assignment against the device you connect, and tighten the housing as the data sheet describes so the sealing stays effective.

When a field-wireable connector is the better choice

Moulded cordsets are convenient, but they come in fixed lengths and force you to coil or extend cable when the distance does not match. A field-wireable connector such as the DOS-1205-G lets the installer use cable from a drum, cut it to the exact route length and terminate it on site. This keeps cable trays tidy, reduces spare stock of different cordset lengths and makes it easier to repair a damaged cable end without replacing the whole run.

• Confirm that the device has a five-pin, A-coded M12 male receptacle with an axial orientation that suits a straight connector.
• Check the outer diameter of the cable you intend to use against the permitted range before buying either item.
• Make sure the conductor cross-section and the current of the circuit stay within the data sheet limits.
• Decide whether the signal needs a screened cable; this type is unshielded.

Good practice during assembly and commissioning

Work on a clean bench or in a sheltered spot whenever possible, because sand or moisture trapped inside the housing during assembly will stay there once it is closed. Use the correct stripping lengths, avoid nicking the conductor insulation, and check that no stray strands can bridge two terminals. After assembly, gently pull each conductor to make sure the screw terminal holds it.

Before connecting the device, test continuity and check for shorts between contacts with a meter, then compare the wiring against the pin assignment of the sensor or actuator. Once plugged in, tighten the locking nut to the specified torque; overtightening the plastic housing does not improve sealing and may damage it.

Use in GCC plants and outdoor installations

Machines and conveyors in Oman and the Gulf are often exposed to dust, high temperatures and washdown or coastal humidity. The connector is listed with an IP67 enclosure rating and a wide head operating temperature range, but that rating depends on correct assembly and the right cable diameter. Route cables so water drains away from the connector rather than toward it, and avoid direct sun on cables where possible to reduce ageing of the sheath. During routine maintenance, check the locking nut is still tight and inspect the cable entry for cracks or signs of strain.

Information for your RFQ

Please state the type code DOS-1205-G and part number 6009719, the quantity, and the device the connector will mate with. If you are unsure whether a straight or angled form suits the installation space, describe the mounting position and we can compare it with the related types listed above.
