Omron E52-P50C D=6.4 Pt100 Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The Omron E52-P50C D=6.4 is a Pt100 resistance temperature detector (RTD) designed for temperature measurement applications spanning 0 to 400°C. This sensor features a non-grounded configuration with exposed lead wires and a 6.4mm diameter protective tube. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in ongoing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for Pt100 RTD sensors is determined by the following critical parameters:

• Element Type: Both parts must use Pt100 sensing elements
• Protective Tube Diameter: 6.4mm diameter requirement ensures mechanical fit in existing installations
• Series Compatibility: E52 series maintains design and interface consistency
• Temperature Range Capability: Substitute must support the required operating temperature window

The identified substitute, E52-P50C-N D=6.4, shares the same series designation, element type, and protective tube diameter. However, differences exist in conductor configuration, terminal type, and protective tube length, which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The E52-P50C-N D=6.4 is an active product within the same Omron E52 series and shares critical mechanical and electrical compatibility parameters with the obsolete E52-P50C D=6.4. Both sensors employ Pt100 elements with identical 6.4mm protective tube diameters, supporting direct mechanical installation in existing mounting configurations.

The substitute provides an extended temperature range (-200°C to 450°C versus 0 to 400°C), which encompasses the original operating window. The shift from non-grounded to 3-conductor system configuration and from exposed lead wires to enclosed terminals represents a design evolution that improves measurement accuracy and environmental protection in industrial applications.

Both parts maintain identical MSL ratings and export classifications, ensuring compliance consistency in supply chain and regulatory contexts.

Frequently Asked Questions (FAQ)

Q: Can the E52-P50C-N D=6.4 directly replace the E52-P50C D=6.4 in existing installations?

A: Mechanical compatibility is confirmed through matching 6.4mm protective tube diameters and E52 series designation. However, the conductor configuration change from non-grounded to 3-conductor system and terminal type change from exposed lead wires to enclosed terminals require validation against the specific measurement circuit and signal conditioning equipment in use.

Q: What is the significance of the temperature range difference?

A: The substitute's extended range (-200°C to 450°C) fully encompasses the original part's operating window (0 to 400°C). This provides additional operational flexibility without compromising performance within the original specification band.

Q: How does the 3-conductor system differ from the non-grounded configuration?

A: The 3-conductor system in the substitute enables lead resistance compensation, improving measurement accuracy in applications where lead wire length or temperature variations affect signal integrity. The original non-grounded configuration does not provide this compensation mechanism.

Q: Does the protective tube length difference affect substitution?

A: The substitute features a 500mm protective tube compared to the original 100mm length. This dimensional change affects immersion depth and thermal response characteristics. Installation geometry must be evaluated to confirm compatibility with existing thermowell or mounting configurations.

Q: Are there packaging or inventory considerations?

A: The substitute is supplied in bulk packaging and maintains active product status with current inventory availability, whereas the original part is obsolete. This ensures long-term supply chain reliability for ongoing applications requiring component replacement.
