Supported Applications
The Omega Copper Extension Wire series is designed for use in temperature sensing systems, specifically as extension wire for sanitary RTD and thermistor applications. The product overview identifies these wires as suitable for connecting sensors to instrumentation where specific insulation properties are required.
Operating Conditions & Performance
Performance limits vary by the selected insulation material. According to the specification table:
- Glass braid insulated wire (EXGG series) is rated for a maximum temperature of 482°C (900°F).
- PFA insulated wire (EXTT series, also referenced as Neoflon® PFA in the overview) is rated to 260°C (500°F).
- Polyvinyl (PVC) insulated wire (EXPP series) is rated to 105°C (221°F).
A note accompanying the data states that maximum temperature ratings apply to whichever component—wire or insulation—is lower. The conductor material for all listed configurations is Copper.
Conductor and Insulation Specifications
- Glass braid: Available in 20 AWG (Solid) and 26 AWG (7 x 34 stranded).
- PFA: Offered in 26 AWG (7 x 34 stranded).
- Polyvinyl: Provided in 24 AWG (7 x 32 stranded).
Configuration Options
The series supports a wide range of configurations defined by conductor count, insulation type, shielding options, and color coding. The model number guide follows the format: EXXX----.
Conductor Counts
Variants are available with 2, 3, or 4 conductors.
Shielding Options
- Unshielded: Standard configurations without a braid shield (indicated by "None" in the Braid column).
- SST Shield: Stainless steel braided shields are available for specific models, denoted by an "-SB" suffix or listed as "SST" in the specification table.
Color Coding and Jacketing
The series utilizes distinct color codes to differentiate conductors:
- ANSI-style coding (Black/Red): Models with Black outer jackets typically use 1 Red / 1 Black, 2 Red / 2 Black, or similar combinations.
- IEC-style coding (White/Red): Models designated for IEC applications often feature White conductors paired with Red. For example, the EXGG-2CUI model lists "1 Red 1 White" and a White outer jacket color.
Lengths and Spooling
The series is offered in various lengths including feet (e.g., 25', 100', 500', 1000') and meters (e.g., 7.5M, 15M, 30M, 150M). A note indicates that conductors can be welded or spliced within the spool.
Key Product Differences
The series is segmented by insulation material and conductor construction:
- Glass Braid (EXGG): Designed for high-temperature service up to 482°C. These models feature a glass braid outer jacket and are available with or without an SST shield.
- PFA / Neoflon® PFA (EXTT): Rated to 260°C, these wires use PFA insulation for chemical resistance and flexibility in sanitary applications.
- Polyvinyl PVC (EXPP): The lowest temperature rating at 105°C. Some Polyvinyl models include a Tinned copper braid shield option (e.g., EXPP-2CUI-24S-TCB-P).
