Lem T5sa -

The is a closed-loop Hall-effect (compensated) current transducer designed for the measurement of DC, AC, and pulsed currents. It belongs to LEM’s renowned “T” series, which is characterized by a split-core (or “split-ring”) design. This split-core feature is critical because it allows the sensor to be installed around an existing conductor without needing to disconnect or reroute the primary cable. The T5SA is specifically rated for a primary nominal current of 500 Amps RMS , with the ability to measure up to ±1000 Amps in overload conditions.

The versatility of the LEM T5SA makes it a staple across various industries. Here are the primary sectors where this sensor excels: lem t5sa

For new designs, evaluate whether you need the T5SA’s sub-microsecond response. If not, a lower-cost open-loop sensor may suffice. But for mission-critical applications where every amp matters, the T5SA remains an excellent choice. The T5SA is specifically rated for a primary

To maximize the performance of the LEM T5SA, engineers should observe best practices during the design and installation phases: If not, a lower-cost open-loop sensor may suffice

Always check the exact datasheet for your part number suffix to confirm output type (e.g., uni-polar 0–5V vs. bi-polar ±4V) and supply requirements.
