Product Information
Full details
The Phoenix Contact 2708999 is a professional 9-pin D-SUB socket connector designed for reliable data transmission in CAN, CANopen, and SafetyBUS p systems operating at up to 1 Mbps. It is ideal for industrial automation engineers and system integrators seeking robust connectivity with enhanced EMC protection. A key benefit is its integrated, switchable termination resistor, which simplifies network configuration. However, users should note its specific pin assignment (2,3,7,9) which requires careful wiring.

Extended Product Information
FAQs
What bus systems is the Phoenix Contact 2708999 compatible with?
This connector is specifically designed for CAN, CANopen, and SafetyBUS p systems.
What is the maximum data rate supported?
The connector supports data rates up to 1 Mbps.
How do I activate the termination resistor?
The termination resistor can be switched on or off using the integrated slide switch located on the connector body.
What is the voltage rating of this connector?
The voltage rating for this connector is 5 V.
Can I use this connector with any D-SUB cable?
This connector is designed for specific bus systems (CAN, CANopen, SafetyBUS p) and has a specific pin assignment (2,3,7,9). It is not a universal D-SUB connector and requires compatible bus cabling.
How does the dual 35° cable entry benefit installation?
The dual 35° entries provide flexibility in routing cables within control cabinets or tight spaces, allowing for a more organized and efficient installation.
What does 'enhanced EMC protection' mean for this product?
It means the connector's housing (metal-plated ABS) offers improved shielding against electromagnetic interference, which is crucial for maintaining reliable data transmission in noisy industrial environments.
Troubleshooting
No communication or intermittent connection.
Verify the specific pin assignment (2,3,7,9) is correctly wired to the bus system. Check that the termination resistor is correctly switched (enabled/disabled) based on network topology. Ensure cable connections are secure at the terminal blocks and inspect the cable for damage.
Low data transfer rates or errors.
Confirm that the bus system is operating within its supported speed (up to 1 Mbps). Check for potential interference from unshielded cables or nearby electrical noise sources. Ensure proper grounding and high-EMC protection is maintained.
Connector does not fit a standard D-SUB port.
Ensure you are using the correct D-SUB connector type. This connector is specifically designed for bus systems and may have a slightly different housing or pinout than standard VGA or serial D-SUB connectors.
