Product description

Heidenhain 387091-03 is an absolute enclosed linear encoder in the LC 200 series for CNC machining centres and machine tools with Mitsubishi controls. With a measuring length of 440 mm and a DIADUR glass scale combining absolute and incremental tracks, the encoder supplies an absolute position value immediately, without a reference run. Signal output uses the Mitsubishi High Speed Serial Interface, designated MITSU01, allowing direct integration into suitable Mitsubishi drive systems without an additional interface converter. The specified accuracy is plus or minus 5 micrometres, with a 20 micrometre grating period. A thermal expansion coefficient of approximately 8 times 10 to the minus 6 per kelvin supports stable measurement across an operating range from 0 to plus 50 degrees Celsius. The aluminium housing protects the scale, scanning carriage and guide against chips, dust and liquids. Protection is IP 53 when installed as specified and IP 64 with compressed air connected. Maximum traversing speed is 180 metres per minute, while permissible acceleration in the measuring direction is up to 100 metres per second squared. Heidenhain 387091-03 operates from 5 volts plus or minus 5 percent and draws no more than 300 milliamperes without load. This used unit was function-tested before dispatch and is available directly from our warehouse in Germany, with worldwide shipping.

FAQ

Frequently asked questions

Contact us
Is there a warranty?

Yes. We provide a 14-day functional warranty for used items. The component must be functional on arrival, and the warranty applies only while the warranty seal remains undamaged.

Depending on availability, we will either provide a replacement or refund the full purchase price after the item has been returned. Further details are set out in the terms and conditions supplied with our quotation.

How quickly do you ship, and which shipping options are available?

We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
