What are the advantages of transmitting encoder or linear gauge signals via CAN communication?

The primary advantages are reduced wiring and improved noise resistance. Compared to Ethernet or BCD outputs, CAN can be configured with simple 3-wire wiring, and its robust error-detection system allows angle and position data to be transmitted safely even in harsh environments. Additionally, multiple measuring instruments can be connected to the same bus, simplifying system configuration.

Is a special command transmission (request) required to acquire CAN communication data?

COCORESEARCH's SPD series (CAN-compatible models) features a function that automatically outputs measurement data to the CAN bus at each configured update time. Since it eliminates the trouble of sending requests from the host system side, program development costs for data collection logers or PCs can be significantly reduced.

Does it support the SAE J1939 protocol used in the automotive sector?

Yes, we have a track record of supporting the SAE J1939 protocol (DLC of 8 bytes or less). It is ideal for integration into CAN networks of construction machinery, agricultural machinery, commercial vehicles, etc., for integrated management of angle and speed data. Individual customization consultations are also available for detailed specifications.

What kinds of sensor signals can be input and converted to CAN?

It supports a wide variety of pulse inputs, including 5V/12V logic, zero-cross, line driver signals, and NPN open-collector. Furthermore, trigger level adjustments (0-9.99V) and low-pass filter settings are also possible, enabling optimal conversion tailored to on-site sensors and noise environments.

Angle, Position & Displacement to CAN Converters Lineup

Signals from gear sensors, encoders, linear gauges, stroke sensors, etc., are converted to CAN using the SPD series.
Can be used as a signal converter / CAN signal conditioner to CAN communication in various fields such as automotive development, construction machinery, and industrial equipment.
Measurement data is automatically output to the CAN bus at each update time, allowing easy data collection.
