SP9250 - Clamp-type probes for SP7001 CAN-FD Sensor

Detailed Product OverviewThe HIOKI SP9200 Screw-type Probe Set is designed for use with the SP7001 CAN-FD Sensor and the SP7100 or SP7150 CAN Interface to enable non-contact detection of CAN or CAN FD signals through the cable insulation. Using capacitive coupling, the two probes together detect the differential signal through the insulation of the CAN H and CAN L lines, without requiring direct electrical contact or wire modification. The screw-type clamping mechanism allows the probes to be firmly fixed to the insulated CAN wires, ensuring a stable capacitive connection even under vibration or mechanical stress. This design makes the SP9200 ideal for long-term or in-vehicle measurements, where durability and signal stability are essential.Each set contains two probes, corresponding to one CAN bus (CAN H and CAN L). When combined with the SP7001 CAN-FD Sensor and a compatible interface, the SP9200 enables reliable, non-intrusive monitoring of CAN or CAN FD communication under real operating conditions. Designed for operation from -40 °C to +85 °C, the SP9200 provides a robust and vibrationresistant solution for contactless acquisition of CAN and CAN FD signals in automotive development and validation environments

Detailed Product OverviewThe HIOKI SP7001 CAN FD Sensor is a sensing unit designed for non-intrusive measurement of CAN and CAN FD signals. Using capacitive coupling, the SP7001 detects differential CAN signals through the insulation of the CAN-H and CAN-L lines, providing accurate signal acquisition without modifying the vehicle wiring. To perform a measurement, the sensor must be used together with an SP7100 (DC powered) or SP7150 (USB powered) CAN Interface, and either an SP9200 screw-type or SP9250 clamp-type probe set. The probes are attached to the insulated CAN lines, while the interface reconstructs the detected signal and outputs it through a Vector-compatible 9-pin Dsub connector, allowing direct connection to Vector Informatik systems or to the HIOKI PW4001 Power Analyzer. The SP7001 is commonly used to expand an existing SP7001-90 set for monitoring a second CAN bus, or by users who wish to build custom configurations tailored to specific test environments. When connected to an SP7100 interface, two SP7001 sensors can operate simultaneously to monitor two independent CAN buses. Supporting communication speeds from 125 kbit/s to 3 Mbit/s (CAN / CAN FD), the SP7001 maintains precise timing and waveform integrity even with high-speed signals. Its noncontact sensing method allows accurate signal detection without influencing the bus load or communication timing, ensuring dependable CAN and CAN FD measurements under real operating conditions. Designed for operation between -40 °C and +85 °C, the SP7001 is suitable for automotive development, EV and HV powertrain validation, and ECU communication analysis. In combination with compatible interfaces and probes, it provides a safe, flexible, and scalable solution for non-intrusive CAN / CAN FD signal monitoring throughout the automotive development process.

Der HIOKI SP7001-90 Non-Contact CAN Sensor ermöglicht eine sichere und effiziente Datenerfassung von CAN- und CAN FD-Netzwerken, ohne dass Kabel beschädigt oder verändert werden müssen.

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 enables accurate, real-time signal acquisition without galvanic contact or interference with the circuit, eliminating the need for wire stripping or connector access and minimizing the risk of short circuits, connector wear, and induced noise. Because the sensor does not alter bus characteristics, it avoids triggering ECU lockouts, allowing safe observation of communication within fully assembled vehicles. Clamp type probes and Vector compatibilityThe clamp type design allows easy attachment even in confined wiring spaces, enabling quick and reliable installation without modifying the harness. It is particularly suited for laboratory measurements, evaluations, and troubleshooting during development or testing, while screw-type probes are recommended for long-term or in-vehicle measurements where vibration resistance is required. The SP7150 CAN interface reconstructs the detected signal and outputs it through a 9-pin Dsub 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 125 kbit/s to 3 Mbit/s with a typical delay of 130 ns, maintaining precise timing and waveform integrity even for 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 CANbased voltage data synchronized with current measurements from external current sensors. This configuration 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 provide a DBC (Database Container) file containing the identifiers and scaling parameters of the required signals. The PW4001 uses this information to extract the correct voltage value from the CAN data stream and combine it with the simultaneously measured current for precise power analysis. The SP7001-95 can be used independently with Vector-compatible systems or other CAN analysis tools. In combination with the HIOKI PW4001 Power Analyzer, it forms a safe, fast, and reliable solution for non-intrusive CAN signal acquisition and power analysis throughout the automotive development process.
