CVS78E-011K2A0BN-0012 CANopen Absolute Encoder Solution

A custom compatible encoder solution can be provided for CVS78E-011K2A0BN-0012 in maintenance, retrofit, replacement, and upgrade projects. This model is a singleturn absolute CANopen encoder with a Ø10 mm solid shaft, clamping flange, and 2 m axial cable connection. Typical production lead time: 15 working days. The engineering objective is to preserve shaft fit, axial cable routing, and 12-bit singleturn CANopen behavior so that field replacement can remain controlled and practical.

Technical Overview of the CVS78E-011K2A0BN-0012 Encoder

The CVS78E-011K2A0BN-0012 belongs to a singleturn absolute rotary encoder platform using CANopen communication with binary code output. The coded structure indicates a Ø10 mm x 20 mm solid shaft, clamping flange, axial exit, 2 m cable connection, aluminum housing, and 12-bit singleturn resolution. The platform supports DS 301 communication and DS 406 / DS 417 device profiles, with programmable behavior according to class 2.

This encoder uses photoelectric sampling and supports operating modes such as polled mode, cyclic mode, and sync mode. Programmable functions include direction of rotation, resolution per revolution, preset value, two limit switches, and eight cam switches. These features make it suitable for installed CANopen systems where both position data and node behavior must stay aligned with the original application.

Industrial Integration Considerations

For this version, the axial 2 m cable is one of the main integration features. Axial cable exit is often chosen where side clearance is limited or where the harness should run along the shaft axis before turning away. In retrofit work, preserving axial routing can reduce cable stress and help avoid changes to nearby guards, motor housings, or support brackets.

The 12-bit singleturn structure should also be matched carefully. In many CANopen applications, the controller is already configured around a defined number of steps per revolution together with preset or cam logic. For that reason, the replacement process should preserve not only the mechanical interface, but also the original node-side measuring format and programmable behavior.

Field Installation and Wiring Notes

For cable versions, shielding and routing practice should remain aligned with the original installation. The wiring should be laid at a large distance from energy lines, cable bending and tensile load should be avoided, and the minimum bending radius should be respected. The screen and 0 V arrangement should remain consistent with the installed wiring concept to preserve stable CAN communication.

Because this is an axial cable version, the available rear clearance should be reviewed before final selection. In compact installations, cable bend space can become the real limiting factor even when shaft and flange dimensions already match.

Custom Compatible Encoder Solution

A custom compatible encoder solution for CVS78E-011K2A0BN-0012 should preserve five engineering points: Ø10 mm shaft geometry, clamping flange mounting, 2 m axial cable layout, 12-bit singleturn CANopen format, and the original node parameter behavior. This helps maintain both field wiring continuity and stable controller-side integration.

Where the installed application already uses preset value, direction setting, resolution scaling, limit switches, or cam switching behavior, those items should be confirmed during engineering review so the final configuration remains aligned with the existing CANopen network logic.

Lead Time and Custom Development

Typical production lead time: 15 working days.

For custom development, the main checkpoints should include shaft diameter, flange reference, rear cable clearance, cable length, node addressing method, baud rate setting, and the required singleturn resolution used in the original control program. The final coded configuration should be reviewed from both the mechanical and CANopen integration sides before release.
