GECU10-MTP-U-M-MTP-U-F RTD & Thermistor Extension Cables

Supported Applications

The Omega RECU, GECU, and TECU series provides RTD and Thermistor Extension Cables designed to extend the connection between temperature sensors and instrumentation. These cables support standard and miniature quick disconnect connectors as well as T Series audio-style connections (TA3M, TA3F). The product line includes retractable extension options for flexible reach and set-length configurations for fixed installations.

Operating Conditions & Performance

The series offers three distinct cable constructions with specific temperature ranges:

• RECU (Retractable): TPE jacketed cables containing three #28 AWG stranded copper wire with PFA insulation. Temperature range is -30 to 150°C.
• GECU (Fiberglass): Fiberglass insulated and jacketed cables containing three #26 AWG nickel plated copper conductors. Temperature range is -73 to 482°C.
• TECU (PFA): PFA insulated and jacketed cables containing three #26 AWG nickel plated copper conductors. The source document lists the temperature range as 267 to 260°C; this value is transcribed exactly as printed despite logical inconsistency.

RECU retractable models feature a 5:1 expansion ratio, allowing initial lengths of 1' or 4' (unstretched) to extend significantly. Set-length cables are available in standard lengths including 3', 10', and 25'. All listed constructions utilize three-conductor wiring as the standard configuration.

Configuration Options

The series supports a wide range of connector configurations, allowing for male-to-female or matching gender connections on either end. Connector types include:

• Standard Quick Disconnect (3-lead): OTP-U-M (male), OTP-U-F (female).
• Miniature Quick Disconnect (3-lead): MTP-U-M (male), MTP-U-F (female).
• 2-Lead Standard: OST-U-M, OST-U-F.
• 2-Lead Miniature: SMP-U-M, SMP-U-F.
• T Series Audio Connectors: TA3M (male), TA3F (female).

Cables are available in 3-conductor configurations as standard. 2-conductor cables are offered specifically with 2-pin connectors (OST or SMP series). Retractable models include initial lengths of 1' and 4', while set-length options cover 0.5', 3', 10', 12', 25', and 30'. T Series connector configurations may incur an additional cost for cable per end.

Key Product Differences

The series is differentiated by the primary model prefix indicating construction type:

• RECU models: Designated as retractable extension cables with TPE jacketing. Model numbers follow the pattern RECU1 or RECU4, followed by connector codes (e.g., RECU1-MTP-U-F-MTP-U-M).
• GECU models: Fixed-length fiberglass insulated and jacketed cables available in 10' and 25' lengths.
• TECU models: Fixed-length PFA insulated and jacketed cables. Available in various set lengths including .5', 3', 10', 12', 25', and 30'. Some TECU variants utilize T Series connectors (e.g., TECU10-TA3F-TA3M).

Ordering requires specifying the model number followed by two connector codes representing each end of the cable. If custom connectors are to be installed, connection codes must be inserted into the order string.
