Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a HEIDENHAIN part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.

|---|---|---|
| Speed | 3 m/s | 15 m/s meets or exceeds |
Rugged incremental head with RS422 or HTL output and 10-30 VDC supply option. Works on linear and rotary scales.
| Published maximum | LIP 200 / LIP 6000 exposed linear | IKS23 |
|---|---|---|
| Speed | 3 m/s | 16 m/s meets or exceeds |
Capacitive absolute linear encoder with a passive 3 g read head and no moving cables; several heads can share one scale.

|---|---|---|
| Speed | 3 m/s | 6 m/s meets or exceeds |
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
What an optical incremental encoder is
An optical incremental encoder measures motion by shining light through or reflecting it from a disc or scale with fine graduations onto photodetectors. As the disc or scale moves, the encoder outputs two square-wave or sine-wave channels in quadrature, called A and B, plus an index pulse once per revolution or at reference marks. The counter in the drive or controller tracks position by counting edges from a home point. Optical encoders achieve very high resolution and accuracy.
When engineers choose an optical incremental encoder
Choose an optical incremental encoder for precise speed and position feedback where homing at power-up is acceptable, such as servo motors, stages and machine tools. They are widely compatible and cost effective. The trade-offs are contamination and power loss: dust, oil and condensation can obscure the optical path, and position is lost when power is removed. For harsh environments, magnetic or inductive encoders may suit better.
How to specify the HEIDENHAIN LIP 200 / LIP 6000 exposed linear
Send these with your enquiry and an engineer can confirm the right LIP 200 / LIP 6000 exposed linear variant or an equivalent:
- Resolution (lines per revolution or µm)
- Output type: TTL, HTL or sin/cos
- Index or reference marks
- Shaft or hollow shaft size (mm)
- Maximum speed (rpm or m/s)
- Supply voltage (V)
- Environment and IP code
Common mistakes to avoid
- Choosing resolution above what the drive input can count
- Running long cables with TTL signals without line drivers
- Ignoring contamination in open optical designs
- Forgetting homing routines after power-up
HEIDENHAIN LIP 200 / LIP 6000 exposed linear: frequently asked questions
What is the HEIDENHAIN LIP 200 / LIP 6000 exposed linear?
Exposed interferential linear encoders with sub-nanometre measuring steps for ultra-precision stages. Published series figures include linear speed 3 m/s, resolution (finest) 0.031 nm. It is made by DR. JOHANNES HEIDENHAIN GmbH; Specify Motion can help source it or propose an equivalent.
Who makes the HEIDENHAIN LIP 200 / LIP 6000 exposed linear?
The HEIDENHAIN LIP 200 / LIP 6000 exposed linear is made by HEIDENHAIN (DR. JOHANNES HEIDENHAIN GmbH) and is listed here for engineers comparing options. Specify Motion is not affiliated with DR. JOHANNES HEIDENHAIN GmbH; brand names are used only to identify the product.
What is the linear speed of the HEIDENHAIN LIP 200 / LIP 6000 exposed linear?
The published series maximum linear speed is 3 m/s. Individual models and sizes in the LIP 200 / LIP 6000 exposed linear 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 HEIDENHAIN LIP 200 / LIP 6000 exposed linear?
Yes. On published figures, Bogen ALS21 and Bogen IKS23 are the closest match from our supply network. An engineer confirms the fit against your application before recommending anything.
What is quadrature output on an incremental encoder?
Quadrature output provides two channels, A and B, offset by 90 electrical degrees. Comparing which leads gives direction, and counting edges on both gives four times the line count in resolution. An index pulse marks a reference position for homing.
What is the difference between TTL and HTL outputs?
TTL outputs use a 5 V differential signal, which suits high frequencies and is commonly used with line drivers. HTL outputs use a higher voltage swing, typically matched to a 10 to 30 V supply, which improves noise immunity on long cables. Match the output type to the drive or controller input.
