Omron E52-P10AE 4M Pt100 Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The Omron E52-P10AE 4M is a Pt100 resistance temperature detector (RTD) designed for temperature measurement applications across a range of -50°C to 250°C. This sensor features a 3-conductor system with exposed lead wires, a 100mm protective tube, and 4 meters of lead wire length. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E52-P10AE 4M is determined by the following critical parameters:

• Element Type: Must be Pt100 RTD
• Lead Wire Length: Must be 13.123' (4m)
• Terminal Type: Must be Exposed Lead Wires
• Protective Tube Dimensions: Length 100mm, Diameter 3.2mm
• Moisture Sensitivity Level: Must be MSL 1 (Unlimited)

The E52-P10AEY 4M qualifies as a substitute based on matching these core parameters. However, the temperature range differs: the substitute operates from 0°C to 250°C versus the original -50°C to 250°C. Additionally, the substitute uses a non-grounded conductor configuration compared to the original 3-conductor system. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The E52-P10AEY 4M is the designated substitute for the obsolete E52-P10AE 4M. Selection of this substitute is appropriate when the application temperature range does not require operation below 0°C. The substitute maintains active product status with Omron, ensuring ongoing availability and supply chain continuity.

For applications requiring operation at temperatures below 0°C, the lower temperature limit of the substitute (-50°C minimum on the original) represents a functional limitation. In such cases, alternative Pt100 sensors with equivalent mechanical specifications and extended low-temperature capability must be sourced.

The transition from a 3-conductor to non-grounded conductor configuration affects signal conditioning and noise immunity characteristics. System integration must account for this electrical difference in measurement circuit design.

Frequently Asked Questions (FAQ)

Q: Can the E52-P10AEY 4M directly replace the E52-P10AE 4M in all applications?

A: Direct replacement is possible only when the application does not require temperature measurement below 0°C. The substitute's minimum operating temperature is 0°C, compared to -50°C for the original. Additionally, the conductor configuration differs, requiring evaluation of measurement circuit compatibility.

Q: What is the significance of the conductor type difference between these parts?

A: The original E52-P10AE 4M uses a 3-conductor system, while the substitute E52-P10AEY 4M is non-grounded. This affects how the RTD connects to measurement instrumentation and influences noise rejection in the measurement circuit. System design must accommodate this electrical difference.

Q: Are both parts manufactured by the same company?

A: Yes, both the E52-P10AE 4M and E52-P10AEY 4M are manufactured by Omron Automation and Safety. The substitute is an active product, whereas the original is obsolete.

Q: Do these sensors have identical physical dimensions?

A: Yes, both sensors share identical protective tube specifications: 100mm length and 3.2mm diameter. Lead wire length is also identical at 4 meters (13.123 feet).

Q: What does MSL 1 (Unlimited) mean for these components?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that these sensors have no moisture sensitivity restrictions and do not require special handling or storage conditions related to humidity exposure.
