Configured for high-density signal interconnects within DCS and PLC control architectures, the YOKOGAWA AKB337-M015 (AKB337 Signal Cable) provides direct physical and electrical execution of multi-channel data transmission.

Suffix Breakdown & Model Matrix

The AKB337 series utilizes standardized suffix codes to define physical length requirements for cabinet-to-cabinet or cabinet-to-field termination unit (FTU) routing:

• Model AKB337: 50-pin to 50-pin interface signal cable.
• Suffix M015: Indicates a fixed cable length of 15 meters.

Hardware Specifications

Process Control Connectivity and Signal Integrity

The AKB337 assembly utilizes a multi-conductor structure designed for low-latency signal coupling between I/O modules and field interface panels. Each conductor is engineered to maintain electrical impedance consistency, minimizing cross-talk between high-density channels. The connectors feature a friction-lock mechanism to prevent accidental disconnection due to mechanical vibration. To ensure compliance with industrial signal standards, the cable employs shielding layers that, when properly grounded at the interface panel, mitigate electromagnetic interference (EMI) and radio frequency interference (RFI) within the control environment.

Frequently Asked Questions

Q: What are the length tolerance specifications for this 15 meter cable?

A: For lengths exceeding 3000 mm, the tolerance is +3% or +1 meter (whichever is smaller) with a -0% tolerance, ensuring the cable meets the specified 15 meter nominal length requirement.

Q: Can this cable be used in high-temperature environments?

A: The cable is rated for an operating temperature range of -20 deg C to +70 deg C; it should not be installed in locations exceeding this upper limit to prevent degradation of the insulation jacket.

Field Installation Guidelines

1. Route the cable through dedicated cable trays or conduits separate from high-voltage power lines to prevent induced noise on the signal lines.
2. Ensure the minimum bend radius is maintained during installation; do not crimp or pinch the cable at sharp cabinet edges.
3. Align the 50-pin connectors carefully with the module or terminal board headers; apply even pressure to engage the friction locks until an audible click is confirmed.
4. Verify all pin-to-pin continuity with a digital multimeter before powering the control system to detect potential open or short circuits resulting from shipping damage.
5. Secure the cable using nylon cable ties at 500 mm intervals to prevent strain on the connector headers caused by the weight of the 15 meter assembly.
