5. Application Information

Mounting Recommendation

1. Mounting method:

2 × Φ 5.3 mm holes

2 × M5 copper or SS304 screws (Recommended torque 1.2 N·m)

Or

4 × Φ 4.2 mm holes

4 × M4 copper or SS304 screws (Recommended torque 1.2 N·m)

2. Primary through hole dimensions:

Φ 38 mm

3. Secondary electrical connection:

Molex 22292031

Crimp Housing: Molex 22012031

Crimping Terminal: Molex 08550102

Remarks

1. IOUT is positive when the primary current (IP) is in the same direction as the arrow indication on the label

and vice versa.

2. Improper connection may result in permanent damage of the sensor.

3. Excessive capacitive load may result in distortion of output signals when measuring high frequency primary

signal. Please refer to Output Voltage vs Load Capacitance Curve.

4. Dynamic performances (di/dt and response time) are best with a single busbar completely filling the primary

through hole.

5. Sensor is customizable upon request.
