Omron, E52 Series (General Purpose Models)

• Previous models with M3 screw connections have been joined by new models with ferrules to help reduce wiring work.

• Ideal for the thermal input devices of Temperature Controllers.

• Select from a wide variety of Temperature Sensors according to the temperature to be measured, location, and environment, and also according to the type and shape of the terminal.

The sleeve resists a temperature range between 0°C and 70°C.
• Heat Resistive (0°C to 180°C): Fully glass-wool-covered with thirty 0.12-dia. conductors (0.3 mm thick) externally
shielded with stainless steel, 4 mm in outer dia. The sleeve resists a temperature range between 0°C and 100°C.

Enclosed-terminal Models

E52-P[]C-N

E52 (General purpose Models) Dimensions 5

Dimensions are given in millimeters, except for the length (L), which is provided in centimeters.

Note: 1. The terminals in the cap indicate polarity (A, B, b).
2. The length L is in centimeters, but “35” is 35 millimeters.
Therefore, for the E52-P35C-N: L = 35 (cm), the sheath length L - 35 = 350 - 35 = 315 mm.

Exposed-terminal Models

E52-P[]B-N

E52 (General purpose Models) Dimensions 7

Dimensions are given in millimeters, except for the length (L), which is provided in centimeters.

Note: The length L is in centimeters, but “40” is 40 millimeters.
Therefore, for the E52-P35B-N: L = 35 (cm), the sheath length L - 40 = 350 - 40 = 310 mm.

Standard Platinum Resistance Thermometers

Enclosed-terminal Models

E52-P[]C-N

E52 (General purpose Models) Dimensions 10

Dimensions are given in millimeters, except for the length (L), which is provided in centimeters.

Note: 1. The length L is in centimeters, but “50” is 50 millimeters.
Therefore, for the E52-P75C-N: L = 75 (cm), the protective tubing length L - 50 = 750 - 50 = 700 mm.
Note: The terminals in the cap indicate polarity (A, B, B).
