ifm Inclination Sensors
Measure absolute angular position and levelling on industrial and mobile machinery. Choose a static sensor for stationary or slowly changing orientation, or a dynamic IMU-based sensor where acceleration, shock and vehicle motion would otherwise distort the angle.
Static JN / ECDynamic JD1 or 2 axesUp to 360°IO-Link / CAN / analogue
AngleUp to 360°Depending on family
Axes1 or 2Application dependent
InterfacesIO-Link / CAN / analogueDepending on product family
ProtectionUp to IP69KCurrent robust variants
Machine applications
Inclination measurement in the system architecture
Inclination sensors reference orientation to gravity, which avoids complex mechanical linkages for many levelling and angle tasks.
02
Loading / unloading angle
Track body angle while tipping and returning to transport position.
03
Bucket & boom orientation
Measure bucket/boom position where dynamic motion must be considered.
04
Platforms & solar tracking
Use static angle measurement for platforms, machine alignment and solar-panel tracking.
Current families
Static and dynamic sensors solve different motion conditions
Choose the dynamic JD family when external acceleration would corrupt a conventional gravity-only inclination measurement.
| Family | Angular range | Axes | Interface | Best fit |
|---|---|---|---|---|
| JN22xx | ±180° | 2 | IO-Link | Static industrial/mobile; also exposes vibration-related data on current route |
| JN21xx | ±180° | 2 | CANopen | Static mobile machinery |
| JN23xx | ±180° | 2 | CAN / SAE J1939 | Static mobile machinery using J1939 |
| EC20xx | ±90° | 1 | Analogue / digital | Compact one-axis mobile applications |
| JD1xxx | 0…360° | 1 | CANopen / SAE route | Dynamic one-axis applications |
| JD2xxx | ±90° | 2 | CANopen / SAE route | Dynamic two-axis applications |
Static inclination
MEMS acceleration measures the gravity vector
Static JN/EC sensors derive orientation from acceleration due to gravity. They are accurate for stationary and quasi-static motion but strong external acceleration can be interpreted as an inclination change.
JN22xxTwo-axis ±180° IO-Link family.
JN21xx / JN23xxTwo-axis CANopen / J1939 routes for mobile machines.
EC20xxCompact one-axis ±90° analogue/digital route.
FilteringCurrent JN architecture provides adjustable filtering for application dynamics.
Dynamic inclination
IMU sensor fusion on accelerating machines
The JD family combines acceleration sensing with a gyroscope so external acceleration can be compensated more effectively than with a purely static inclinometer.
01
Accelerometer + gyroscope
Combines gravity information with angular-rate data to improve measurement during vehicle/machine dynamics.
02
High measurement dynamics
Suitable for mobile equipment where boom, bucket or vehicle movement creates acceleration.
03
Mobile architecture
Current JD families use CAN-based interfaces and are intended for rugged mobile machinery.
JN22xx IO-Link
Angle plus machine-condition data on one connection
Current JN22xx static inclination sensors provide raw 3D accelerometer data sequentially with inclination values over IO-Link, and calculated vibration indicators can also be available.
01
2-axis inclination
Use the same device for levelling or angular position.
02
3D accelerometer values
Expose additional acceleration information for engineering or monitoring.
03
a-Peak / v-RMS
Current JN architecture can provide calculated vibration values and selectable filtering.
