Typical applications
What a magnetic rotary encoder is
A magnetic rotary encoder measures angle by sensing the field of a magnet with Hall-effect or magnetoresistive sensors. On-axis designs place a diametrically magnetised magnet on the shaft end above a sensor chip; off-axis designs read a multi-pole magnetic ring around a hollow shaft. Signal processing turns the field into absolute or incremental position. Because there is no optical path, magnetic encoders tolerate dust, oil, moisture and vibration, typically with moderate resolution and accuracy at low cost.
When engineers choose a magnetic rotary encoder
Choose a magnetic rotary encoder for robust, compact feedback in harsh or cost-sensitive applications, such as motors, AGVs, robotics, agricultural and mobile machinery. Off-axis rings suit hollow joints. The trade-offs are accuracy and magnetic interference: accuracy is typically lower than optical, and strong stray fields from brakes or motors can affect the reading. For high precision, choose optical. Consider shielding and mounting tolerances carefully.
How to specify the Bogen IKS23
Send these with your enquiry and an engineer can confirm the right IKS23 variant:
- Resolution (bits or counts)
- Accuracy (degrees or arcmin)
- Absolute or incremental output
- On-axis or off-axis ring mounting
- Interface: SSI, BiSS, SPI, PWM or analogue
- Mounting tolerances: gap and runout (mm)
- Environment and IP code
Common mistakes to avoid
- Mounting near brakes or motor magnets without shielding
- Exceeding the allowed air gap or runout
- Expecting optical accuracy from a magnetic encoder
- Overlooking calibration after installation
Bogen IKS23: frequently asked questions
Can you help replace Bogen IKS23 or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Bogen IKS23?
Rugged incremental head with RS422 or HTL output and 10-30 VDC supply option. Works on linear and rotary scales. Published series figures include linear speed 16 m/s. It is available through our supply network, and our engineers can confirm the right variant for your application.
Who makes the Bogen IKS23?
The Bogen IKS23 is made by Bogen (Bogen Magnetics) available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.
What is the linear speed of the Bogen IKS23?
The published series maximum linear speed is 16 m/s. Individual models and sizes in the IKS23 range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the Bogen IKS23?
We can assess suitable replacement options. Our engineers can review the original model and propose options for your load, speed and environment. An engineer confirms the fit against your application before recommending anything.
Are magnetic encoders as accurate as optical encoders?
Typically not. Magnetic encoders tolerate contamination and vibration well but usually have lower accuracy and resolution than optical encoders of similar size. Self-calibration and good mounting can improve results. For high-precision positioning and metrology, optical encoders remain the usual choice, while magnetic types win on robustness and cost.
What is the difference between on-axis and off-axis magnetic encoders?
On-axis encoders read a single magnet on the end of a shaft, which is simple and compact. Off-axis encoders read a magnetic ring around a shaft, which leaves the centre free for hollow shafts or cables. Off-axis designs are more sensitive to mounting tolerances.
