AS5 CANopen Inclinometer
The AS5C DS-410 CANopen Inclinometer delivers precision angle measurement for demanding off-highway and industrial applications. Communicating via the CANopen protocol (CiA DS-301, DS-410, DS-305), it supports single-axis 360° measurement and optional dual-axis X-Y configuration — with resolution down to 0.01° and fully configurable PDO mapping via SDO writes. Compact, rugged, and built in the USA, the AS5 integrates directly into any CANopen network without additional hardware.

| NMT Auto-Start Option (Object 0x1F80) | Transitions to OPERATIONAL state automatically on power-up — simplifies network startup sequence |
| Parameter Storage to Flash (Object 0x1010) | All SDO configuration changes persist through power cycles — no re-programming on restart |
| 4-Wire Interface (VBAT, GND, CANH, CANL) | Minimal wiring footprint — ISO 11898-2 differential pair for robust noise immunity |
| Customer-Specific Part Numbers (AS5CMnnnnn) | Factory-configured to your application — pre-mapped, pre-tested, ready to install |
Mounting and Integration
The AS5C installs directly on any equipment frame, boom, mast, or structural member where tilt or angle measurement is required. The sensor connects to the CAN bus via a four-wire harness (VBAT, GROUND, CANH, CANL) using an ISO 11898-2 twisted pair for the differential CAN signal. Node ID and CAN bit rate are configured via LSS using a CANopen device manager tool before installation on the live network. All PDO mapping, resolution, and filter settings are written via SDO and saved to flash. The sensor ships factory-configured to the customer part number specification and is ready to install.
Typical Applications
- Aerial work platforms — platform level verification and boom angle feedback
- Cranes — slew, boom, and jib angle monitoring on mobile and tower cranes
- Construction and off-highway equipment — boom, arm, and blade pitch control
- Agriculture — sprayer boom leveling, header height, and implement tilt feedback
- Material handling — mast tilt and load angle on reach stackers and forklifts
- Telehandlers — boom angle feedback for load-moment and stability systems
- Rail and utility — structure angle monitoring and positioning feedback
FAQs
Q: What CANopen protocols does the AS5 inclinometer support?
A: The AS5C communicates using three CiA standards: DS-301 v4.02 (the CANopen Application Layer and Communication Profile), DS-410 v3.0 (the Device Profile for Inclinometers), and DS-305 v2.2 (Layer Setting Services for node ID and bit rate configuration). This means it integrates with any standards-compliant CANopen master controller without custom protocol work.
Q: What is the angle resolution of the AS5 inclinometer?
A: The default resolution is 0.01° — angle values transmitted as 16-bit signed integers in hundredths of a degree. Resolution can be changed to 0.1° (tenths) via an SDO write to Object 0x6000, with slope parameters enabled via Objects 0x6011 and 0x6021. The change must be saved to flash by writing “save” to Object 0x1010:01 to persist through a power cycle.
Q: How do I set the Node ID and CAN bit rate on the AS5?
A: Node ID and CAN bit rate are configured using the LSS (Layer Setting Services) protocol via your CANopen device manager tool. OEM Controls strongly recommends having only one device on the bus when making LSS changes. Any change to Node ID or bit rate takes effect only after an NMT Reset command or power cycle.
