Supported Applications
The Omega CH62 series comprises Round Terminal Blocks and Transition Adaptors designed for thermocouple connections. The product overview identifies these components as providing quick connections between standard and miniature connector systems, available in ANSI or IEC color-coded versions for various thermocouple calibrations. Round Terminal Blocks are rugged blocks intended for single or dual wire pair connections.
Operating Conditions & Performance
The series operates within an ambient temperature range of -29 to 220°C (-20 to 425°F). The housing material is specified as Rugged Glass-Filled Nylon for the Round Terminal Blocks. Transition Adaptors feature One-Piece Molded Construction.
Dimensions and Compatibility
• Diameter: 31.7 mm (1.25")
• Thickness: 9.7 mm (0.38")
• Cable/Probe Fitment: Designed to fit metal-sheathed cable or probes between 1.5 and 6 mm (⅛ and ¼") in diameter.
• Connection Type: Compression fitting (1/8 BSP) for OMEGACLAD wire; a ⅛ NPT compression fitting is used to adapt to probes or cables (sold separately).
Configuration Options
The series supports multiple configurations across terminal block positions and adaptor types. Model numbers follow the format CH<62-64>-<(*)>, where the number indicates the quantity of terminals.
Terminal Block Positions
• CH62: 2 Terminals
• CH63: 3 Terminals
• CH64: 4 Terminals
Transition Adaptor Configurations (TAS Series)
The series includes Transition Adaptors available in all thermocouple calibrations, including Tungsten-Rhenium alloys. Any combination of male and female contacts for miniature and standard positions is offered.
• TAS-(*)-1: Male standard to male mini
• TAS-(*)-2: Female standard to male mini
• TAS-(*)-3: Male standard to female mini
• TAS-(*)-4: Female standard to female mini
• TAS-U-5: Male banana plug to female mini (Uncompensated)
• TAS-U-6: Sheathed banana plug to banana plug (Uncompensated)
• TAS-U-7: Sheathed banana plug to banana plug set (Uncompensated)
Note: TAS-U-5, TAS-U-6, and TAS-U-7 are only available in uncompensated calibration.
Calibration Options
The series supports calibrations J, K, T, E, R/S, N, or U (uncompensated). Models may be ordered with G, C, or D calibration at an additional cost; however, models 1 and 3 are not available for these specific calibrations. An "-IEC" suffix is added to order IEC color code versions.
Key Product Differences
Variants within the CH62 series differ primarily by terminal count (CH62, CH63, CH64) and thermocouple calibration type. The model number includes a letter suffix indicating the specific calibration: C, E, J, K, KI, S, T, or U.
• Standard Calibrations: Models include variants for Type C (CHxx-C), Type E (CHxx-E), Type J (CHxx-J), Type K (CHxx-K), Type N/KI (CHxx-KI/CHxx-TI in some listings, though source specifies KI/N context), Type S/R/S-OR (CHxx-S/CHxx-S-OR), and Type T (CHxx-T).
• Uncompensated: Models ending in -U represent uncompensated versions.
The series also encompasses Transition Adaptors with model patterns TAS-(*)-[1-7], where the asterisk denotes the calibration letter. Specific ordering examples include CH62-K for a 2-position round terminal block, Type K, and TAS-K-2 for an adaptor with female connection on the standard end and male connection on the miniature end.
