Phoenix Contact SAC-3P-M8MS/3.0-PUR Series, Straight M8 to Unterminated Cable assembly, 3m Cable. ...Phoenix Contact SAC-3P-M8MS/3.0-PUR Series, Straight M8 to Unterminated Cable assembly, 3m Cable. Sheath Colour: Black, Cross Sectional Area: 0.25 mm², American Wire Gauge: 24 AWG. Connector A Housing Gender: Plug. Sheath Material: Polyurethane PUR. Shielding: Unshielded. Rated current 4A, Rated voltage 60V. The cable features a straight M8 connector on one end and free conductors on the other, making it suitable for various sensor and actuator applications. It has a durable polyurethane PUR sheath and is black in color.
This Phoenix Contact 1681677 sensor/actuator cable is designed for industrial automation applications, offering a reliable 3-meter connection between sensors/actuators and control systems. Its primary benefit is its durable polyurethane (PUR) sheath, providing resistance to oils and chemicals common in industrial environments. A potential caveat is its fixed 3-meter length, which may not suit all installation requirements. Key features include a straight M8 male connector, 3-position wiring, a robust 4A/60V rating, and a flexible PUR cable suitable for demanding conditions.

Extended Product Information
FAQs
What is the IP rating of the M8 connector on this cable?
While the M8 connector itself typically offers good protection when properly mated, the specific IP rating of the cable assembly depends on the mating connector. When securely connected to a compatible IP-rated receptacle, it generally provides a high level of protection against dust and water ingress.
Can this cable be used for high-speed data transmission?
This cable is designed for standard sensor and actuator signals (4A/60V). It is not typically rated or optimized for high-speed digital data transmission protocols like Ethernet, which require different cable specifications.
What does 'unterminated' mean for the free cable end?
Unterminated means the cable end has exposed conductors (wires) that need to be manually connected to terminals, a junction box, or another connector, allowing for custom wiring configurations.
What is the advantage of a PUR sheath compared to PVC?
Polyurethane (PUR) sheathing is generally more resistant to oils, chemicals, abrasion, and UV light than PVC, making it more durable and suitable for demanding industrial environments.
How do I determine the correct pinout for the unterminated end?
The product description indicates a 3-position connector. For standard M8 sensor/actuator applications, Pin 1 is typically V+ (power), Pin 3 is GND (ground), and Pin 4 is Signal (or vice versa for actuators). Always consult the specific documentation for your sensor or actuator to confirm the exact pinout.
What is the maximum operating temperature?
The cable is rated for operation in temperatures from -25°C to 90°C.
Is this cable shielded?
No, this specific model (1681677) is described as unshielded. For environments with significant electromagnetic interference (EMI), a shielded version might be necessary.
Troubleshooting
No signal transmission from sensor/actuator
Verify the M8 connector is fully seated. Check the wiring at the unterminated end for loose connections or incorrect polarity. Ensure the rated voltage and current are within limits for the connected device.
Intermittent signal or performance issues
Inspect the cable for physical damage. Ensure the M8 connector is securely fastened. Check for electromagnetic interference in the environment; consider shielded cables if necessary.
Connector is difficult to mate/unmate
Ensure the M8 receptacle is clean and free of debris. Do not force the connection; verify alignment of pins and sockets. The M8 connector is designed for hand-tightening.
Pros and Cons
Pros
Robust and durable polyurethane sheath offers excellent resistance to industrial chemicals and abrasion.
Standard M8 connector ensures broad compatibility with many sensors and actuators.
Halogen-free construction enhances safety in industrial settings.
Suitable for a wide operating temperature range, from -25°C to 90°C.
3-meter length is practical for many common automation setups.
Cons
Fixed 3-meter length may be too short or too long for specific applications.
Unterminated end requires proper wiring and termination, adding an installation step.
M8 connectors may not be suitable for applications requiring higher power or data rates.
Typically unshielded, which could be a limitation in environments with high electromagnetic interference.
Setup, Compatibility & Care
Setup:
Prepare Unterminated End: Carefully strip the outer PUR sheath and insulation of the free conductors according to your termination requirements.
Connect Conductors: Connect the exposed wires to the appropriate terminals on your control device (PLC, I/O module, terminal block), ensuring correct polarity and connection.
Connect M8 End: Plug the straight M8 male connector into the corresponding M8 female receptacle on your sensor or actuator.
Secure Connection: Ensure the M8 connector is hand-tightened or secured as per the mating connector's instructions.
Compatibility:
Connectors: Compatible with standard M8 female connectors. Check the pinout (3-position) to match your device's requirements.
Sensors/Actuators: Suitable for devices with M8 male receptacle and requiring a 3-position connection, a rated current up to 4A, and a voltage up to 60V.
Control Systems: Can be integrated with PLCs, data acquisition systems, and other industrial control equipment that utilizes M8 interfaces and standard signal wiring.
Care:
Cleaning: Clean the cable and connectors using a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the PUR sheath.
Inspection: Regularly inspect the cable for any signs of physical damage, such as cuts, abrasions, or kinks, particularly near the connectors.
Strain Relief: Ensure proper strain relief is applied at both ends to prevent excessive pulling on the conductors and connectors.
