Connecting Cable | GJR2370500R2 | ABB

Technical Specifications

The ABB GJR2370500R2 is a specialized industrial cable assembly for signal transmission and communication in automation and control systems. The GJR2370500R2 features a cable length of 5 meters, providing sufficient reach for connections between control units, interface modules, and peripheral devices in industrial installations.

Troubleshooting & Commissioning Checklist

Outer Jacket Integrity: Inspect the full 5-meter gray PVC/PU jacket for deep gashes, crimps, or exposure of the internal copper shielding mesh. Wet-end factory environments can compromise compromised jackets.
Gold Pin Alignment: Look directly inside both DB25 female sockets. Verify that all 25 socket receptacles are perfectly circular, clean, and not recessed or pushed backward into the plastic housing.
Bend Radius Adherence: Ensure that the line routing maintains a minimum bend radius of ≥ 80 mm inside the control cabinet. Avoid sharp 90-degree corners to prevent microscopic copper fatigue inside the 24 AWG data lines.

Field Engineering Considerations

Combating VFD Noise: Heavy industrial settings are filled with high-frequency electromagnetic interference from Variable Frequency Drives and heavy switchgear.
The 360-Degree Bond: The GJR2370500R2 features an integrated tinned copper braid shield. For this shield to function as an effective Faraday cage, the metal backshell of the DB25 connectors must maintain solid, 360-degree contact with the metal chassis ground of the module ports.

Technical FAQ

Q: Why is it critical to fully tighten the mechanical locking screws on the ABB GJR2370500R2 connectors during installation?
A: Tightening the screws maintains a secure, high-pressure gas-tight connection that prevents fretting corrosion and protects the serial link against heavy plant machine vibrations.

Q: Is it safe to unplug the ABB GJR2370500R2 DB25 connectors while the control rack is fully energized?
A: No, the interface lacks hot-swap capabilities; pulling the connectors live can cause voltage transients on the serial pins that can permanently blow out the sensitive UART transceiver chips on the host controller.

Q: What physical installation limit must field engineers observe when routing the ABB GJR2370500R2 cable through tight wire ducts?
A: Engineers must maintain a minimum dynamic bend radius of at least 80 mm; forcing the cable into sharp 90-degree corners will crush the internal low-capacitance insulation and cause conductor micro-fractures.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
A: All items in stock are tested by engineers, packed in professional ESD packaging, and shipped via express logistics with a global delivery time of 24–48 hours.

Q: How long does global shipping take?
A: Stock items are typically dispatched within 24 hours. Shipments are sent via DHL or FedEx Express, taking approximately 3–5 days to reach Asia, 4–6 days to Europe and the Middle East, and usually arriving within a week in major industrial regions worldwide.

Q: If the model I need is not listed on the website, can I request a quote?
A: Yes. We hold over 200,000 SKUs of industrial spare parts in stock, and many long-tail models are not listed in full. You can send us an RFQ (Request for Quote) directly, and we will provide wholesale pricing promptly.
