SP7001-95 Non-contact CAN/CAN FD Sensor

Measuring set SP7001-95 includes: 2x probe SP9250 + 1x sensor SP7001 + CAN Interface SP7150 (including step clamp, power cable L9510 and GND cable).

Power supply from USB bus or Z1013.

Detailed Product Overview

The HIOKI SP7001-95 CAN Sensor Set combines the SP7001 non-contact CAN sensor, two SP9250 clamp-type signal probes, and the SP7150 CAN interface to enable non-intrusive acquisition of CAN and CAN FD signals without any modification to vehicle wiring. Using capacitive coupling, the two SP9250 probes are clamped around the insulated CAN H and CAN L lines to detect differential signals through the cable sheath. This method provides accurate, real-time signal acquisition without galvanic contact or circuit interference, eliminating the need for wire stripping or connector access and reducing the risk of short circuits, connector wear, and induced noise. Because the sensor does not alter bus characteristics, it prevents ECU lockouts and allows safe monitoring of communication within fully assembled vehicles.

Clamp type probes and Vector compatibility

The clamp-type design enables fast attachment even in confined wiring spaces, allowing quick and reliable installation without modifying the harness. It is ideal for laboratory measurements, evaluation tasks, and troubleshooting during development or testing, whereas screw-type probes are recommended for long-term or in-vehicle measurements where enhanced vibration resistance is required.

The SP7150 CAN interface reconstructs the detected signal and outputs it through a 9-pin D-sub connector compatible with Vector Informatik interfaces and the HIOKI PW4001 Power Analyzer. This allows direct connection to CAN analysis tools or to the PW4001 without additional adapters. Powered via a USB Type-C connector, the compact interface supports communication speeds from 125 kbit/s to 3 Mbit/s with a typical delay of 130 ns, ensuring precise timing and waveform fidelity even with high-speed CAN FD. Automatic polarity detection compensates for reversed probe orientation, and a selectable high-sensitivity mode ensures stable operation on long or shielded cables.

Power analysis with PW4001

When connected to the HIOKI PW4001 Power Analyzer, the SP7001-95 provides CAN-based voltage data synchronized with current measurements from external sensors. This setup enables accurate power calculation on high-voltage systems without direct connection to battery terminals, improving operator safety and test efficiency. To interpret or decode CAN data, the user must supply a DBC file containing signal identifiers and scaling parameters. The PW4001 uses this information to extract the correct voltage value from the CAN data stream and combine it with the measured current for precise power analysis.

The SP7001-95 can also be used independently with Vector-compatible systems or other CAN analysis tools. When paired with the PW4001, it provides a safe, fast, and reliable solution for non-intrusive CAN signal acquisition and power analysis throughout the automotive development process.
