Supported Applications
The Omega M12CM-RTD series consists of high temperature extension cables designed for use with M12 probes, sensors, and transmitters in elevated thermal environments. These assemblies serve as signal extensions between the sensing element and instrumentation.
• M12 probe connections
• High-temperature sensor interfaces
• Transmitter cabling applications
Operating Conditions & Performance
The series is rated for a process temperature of 205°C (400°F). The cable construction features FEP insulated conductors with an IP65 moisture resistance rating. Vibration performance is validated to MIL-STD-202G, Method 204D, Test Condition A (10g's from 10 to 500 Hz) when installed on an M12 probe.
Electrical and Physical Characteristics
• Cable diameter: approximately 3.3 mm (0.13")
• Conductor resistance: approximately 0.08 Ω per meter (0.024 Ω per foot)
Configuration Options
The M12CM-RTD series is configurable across connector orientation, length, and termination style to accommodate specific installation geometries.
Connector Configurations
• Straight female LCP over-molded M12 connectors (4-pin)
• Right angled female LCP over-molded M12 connectors (4-pin)
Cable Lengths and Terminations
Standard lengths include 2, 5, 10, 15, and 20 m (6.5, 16.4, 33, 49, and 65.6 ft). The opposite end of the M12 connector terminates in stripped leads.
Conductor Specifications
• Electrical connection: 4-wire #24 AWG stranded silver-plated copper conductors
Key Product Differences
Variants within the series are distinguished by connector orientation and cable length. The model number guide follows the format M12CM-T24SSPC--. Examples include:
• M12CM-T24SSPC-SF: Straight female connector
• M12CM-T24SSPC-RF: Right angled female connector
Specific model examples documented in the series data sheet are M12CM-T24SSPC-SF-2 and M12CM-T24SSPC-RF-2. The straight female connector has a length of 49.5 mm (1.94"), while the right angled female connector measures 31.9 mm (1.25") in length.
