Specifications TMR7503-B Unibody Low Temperature-Drift Current Sensor MultiDimension Technology Co., Ltd. http://www.dowaytech.com/en/
- Parameters Definition And Formula 1) Output Voltage VOUT = VOE + S × IP VOUT stands for current sensor output voltage at given primary current, VOE stands for offset error, S stands for sensitivity, IP stands for primary current. 2) Accuracy XG = MAX IP ∈ [-IPN, IPN] VOUT - (S × IP) S × IPN × 100% IPN stands for nominal primary current 3) Sensitivity S = VOUT(@ IPN) - VOUT(@ -IPN) 2 × IPN VOUT@ IPN and VOUT@-IPN stand for the voltage output at IPN and -IPN respectively. 4) Linearity εL = MAX IP ∈ [-IPN, IPN] VOUT - VOE + S× IP S × IPN × 100% S and VOE stand for the average values of the sensitivity and offset error. 5) Symmetry εSYM = VOUT(@ IPN) - VOE VOUT(@ -IPN) - VOE × 100% 6) Hysteresis VOH = MAX ∆H ∆H is the maximum residual voltage between full scale positive and negative nominal current .

Figure 17. Connection diagram of TMR7503
- Mounting method: Choose one of 3 × Φ 4.5 mm holes
- Primary through-hole dimensions: 20 mm × 10 mm
- Secondary terminal: Molex 22041041 (previous 5045-04A series)
- VOUT is positive when the primary current is in the same direction as the arrow indication on the label and
- Improper connection can cause permanent damage of the sensor.
- Excessive capacitive load may cause the distortion of output signals when the primary frequency is too
high. Please refer to Figure 4.
- Sensor is customizable upon request.
- Dynamic performances (di/dt and response time) are best with a single busbar completely filling the primary
