Monitor CAN FD/CAN Signals Without a Sub-Harness
NON-CONTACT CAN SENSOR SP7001, SP7002
Description
The SP7001 and SP7002 are CAN and CAN FD signal sensors that use non-contact technology to accurately capture CAN bus signals necessary for vehicle and next generation equipment evaluation and development. Improve testing productivity and efficiency by eliminating the need to peel away cable insulation or use a sub-harness that is traditionally required to obtain signals.
Key Features
• Acquire CAN data immediately, simply by hooking probes to the cables
• Eliminate concerns by using non-contact sensing technology
• Use in a diverse array of development and evaluation applications that demand reliability

Non-Contact CAN Sensor SP7001 : Capture vehicle network CAN signals over cable insulation
The SP7001 Non-Contact CAN Sensor is designed to capture CAN signals simply by clipping over the insulation of differential CAN bus wires. Eliminate impact to the ECU (Engine Control Unit) for stable and steady analysis and reduce prep time before testing.
Monitor CAN FD/CAN signals without a sub-harness
1. No modification of vehicle cables Acquire CAN data immediately, simply by hooking probes to the cables. 2. No impact on the CAN bus or ECUs Eliminate testing concerns by using non-contact sensing technology. 3. Accurate, reliable signal capture Use in a diverse array of development and evaluation applications that demand reliability.
New approach means dramatically fewer man-hours
Capture CAN signals without the need to fabricate sub-harnesses or strip back cable insulation so as to significantly reduce the number of manhours spent on test preparation.
Easy setup
Hook the probes to insulated CAN cables. Now you’re ready to acquire signals.
Continue using your existing CAN analysis system
Industry-standard CAN output connector pin layout. Customers who already have a CAN analysis system such as those manufactured by Vector Informatik GmbH need only connect the sensor to that system’s input terminal (via a D-sub 9-pin connector).
Wide -40°C to 85°C operating temperature
Acquire CAN signals in environments from -40°C to 85°C (-40°F to 185°F), the temperature range required in vehicle testing.
Power with 12 V and 24 V vehicle batteries and other sources
Use a DC power supply with the Power Cable L9500*1, a standard accessory. If using commercial AC power, use the AC Adapter Z1008*2. *1 Included with the SP7100. *2 Sold separately as an option.
Connect probes without worrying about CAN bus polarity
If you’re using automatic input polarity mode, the SP7001/SP7002 will automatically switch the input polarity to ensure you can capture CAN signals properly, even if the probes are connected in reverse relative to the CAN bus’s polarity (CAN_High/CAN_Low).
Adjustable sensitivity accommodates a variety of conditions
Use high-sensitivity mode to broaden the detection level when the CAN signal amplitude is low relative to the CAN standard or when you are unable to detect a signal due to cable conditions.
Designed not to trigger ECU security lock-outs
The SP7001/SP7002 acquires signals without changing the electrical characteristics of the CAN bus. Even if the vehicle is equipped with an ECU that has a security lock-out function designed to detect changes in the CAN bus’s electrical characteristics, you’ll be able to carry out testing without worrying about getting locked out.
Vibration resistance designed for on-road testing
The sensor delivers noise immunity designed for in-vehicle testing in a variety of road environments. Acquire CAN signals in a stable manner in evaluation testing not only on test courses, but also in vehicles undergoing test-drives on public roads.
Noise immunity robust enough for use with EVs and HVs
The sensor delivers enough noise immunity to acquire CAN signals in a variety of noise environments. Acquire CAN signals in a stable manner, even with vehicles such as EVs and HVs that rely increasingly on electric equipment.
Carry out testing on public roads with peace of mind since no vehicle modifications are needed
Because it acquires signals without making electrical contact, the SP7001/SP7002 is ideal for use in tests where CAN bus insulation cannot be modified. Also apply in the development of advanced driver assistance systems (ADAS) and self-driving technology.
Acquire CAN signals with the same accuracy as the contact method
The non-contact method captures CAN signals reliably and accurately, just like the contact method. In addition, with a CAN signal detection delay of just 130 ns, the sensor delivers real-time performance.
Non-contact method also excels with CAN FD high-speed signals
Unlike the contact method, the non-contact method does not distort the original signal when probing the CAN bus. This approach avoids communication errors caused by degraded communications quality. *Model with CAN FD support: SP7001
Reliably capture even infrequent events
The Non-Contact CAN Sensor does not affect the electrical characteristics of the CAN bus, allowing you to reliably catch the occasional CAN error events.
Acquire signals without needing to go through a central gateway
Only a tiny percentage of all CAN signals can be acquired from the OBD-II connector that is used in vehicle diagnostics. By using the product with the vehicle’s internal CAN bus, you can acquire all CAN signals.
Ideal for all development processes ranging from unit to vehicle testing
1. Reduce the number of man-hours needed to prepare the vehicle for testing and then restore to original condition The SP7001/SP7002 lets you acquire CAN data without time-consuming preparations such as fabricating sub-harnesses and modifying cables. In addition, all you’ll need to do after the test is finished is remove the sensors. There’s no impact on the vehicle. 2. Safely conduct noise application tests thanks to the isolated design When checking the operation of vehicle sensors and ECUs, for example with tests that apply noise, the sensor protects connected devices from damage and malfunctions caused by noise because it is isolated from CAN signal lines. 3. Fostering smooth validation The sensor makes it easy to conduct standalone and combination evaluations, including even sudden reevaluations following changes made to vehicle parts during the validation process.
Ever-increasing vehicle electrification and data volume
The number of ECUs in vehicles is growing rapidly as ADAS and other safety features are enhanced and as adoption of self-driving vehicles increases, leading to more complex CAN buses. The convenience of the Non-Contact CAN Sensor makes it easy to acquire the information you need.
Acquire CAN signals used in a broad range of industries
It can be used not only in automobiles but also in various fields where CAN signals are used.
