ROCKWELL TC-505-02-4M5 – Thermocouple Extension Cable for Reliable Temperature Signals

From my experience, TC-designated codes with a “-4M5” suffix typically indicate a thermocouple extension lead at 4.5 meters in length. The ROCKWELL TC-505-02-4M5 appears to be a factory-terminated thermocouple extension cable designed for stable, low-noise millivolt signal transmission between a temperature sensor and a PLC or temperature controller. You might notice that it fits neatly into retrofit projects where a clean, shielded run is more valuable than adding another junction in a control panel.

Company’s Order Placement Process and Guarantees

• Warranty period: 365 days
• Delivery time: 1 week for in-stock items; no more than one month at the latest
• Payment method: 50% advance payment, full payment for delivery
• Express delivery methods: FedEx, UPS, DHL

Key Features

• 4.5 m factory length – The “-4M5” code typically denotes a 4.5 m run, long enough for panel-to-machine routing without excess slack.
• Thermocouple signal integrity – Shielding and matched conductors help maintain stable millivolt readings for Type J/K/T sensors in most cases.
• PLC/temperature controller friendly – Intended for connection to thermocouple input modules or dedicated temperature controllers; simple, passive wiring with no external power.
• Rugged industrial build – Typically uses flexible jacket materials to resist oils and abrasion in standard control cabinet and machine environments.
• Time-saving installation – Pre-terminated ends reduce wiring errors and commissioning time, especially on repeat builds.

Technical Specifications

Application Fields

This cable suits production environments where temperature accuracy matters and noise rejection is a must. Typical deployments include:

• Food & beverage ovens, proofers, and retort lines connecting to PLC thermocouple cards
• Heat-treatment furnaces and kilns monitoring multiple zones
• Extrusion and molding machines with barrel/heater band feedback
• Pharma and biotech skids where clean routing and stable readings are critical
• General process skids tying field thermocouples back to control panels

A packaging OEM told us they switched to this length to standardize builds—no more cutting and re-terminating on site, which seems to cut commissioning time by a day in many cases.

Advantages & Value

• Reliability – Stable thermocouple signal transmission with proper shielding reduces drift and nuisance alarms.
• Compatibility – Works with standard thermocouple input modules from major PLC platforms, including Allen‑Bradley modules, in most cases.
• Cost Control – Pre-terminated cable lowers panel labor and avoids rework from wiring mistakes.
• Support – We can help match the cable to your thermocouple type and input card to avoid cold-junction and polarity pitfalls.

Installation & Maintenance

• Environment – Route in dry, ventilated cabinets or protected tray; keep away from VFD motor leads and high-voltage runs to minimize noise coupling.
• Shielding – Maintain continuous shield; bond at the control side as your module manual specifies (typically one end only).
• Polarity – Thermocouple leads are polarity-sensitive; match positive/negative conductors to the module terminals.
• Bend Radius – Respect minimum bend radius (usually 5–8× cable OD) to avoid conductor fatigue.
• Routine Checks – Periodically inspect for jacket abrasion, loose terminations, and verify readings with a handheld calibrator; update controller firmware when applicable to improve CJC handling.

Quality & Certifications

• CE and RoHS compliance typically applicable to industrial signal cables
• UL AWM/CMG recognition may apply depending on jacket type and build
• Manufactured under ISO 9001 quality systems (typical for this category)
• Manufacturer’s warranty: 365 days

If you’re matching this cable to a specific thermocouple type or input card, share your module model and sensor alloy. We’ll confirm the conductor metallurgy and termination detail so you get precise readings without trial-and-error.
