Product description

Heidenhain 216750-BF is a sealed incremental linear encoder from the LS 703 series for direct measurement on linear axes of CNC machine tools and machining centres. The 216750-BF has a measuring length of 720 mm and an accuracy class of ±5.0 μm, supporting precise position feedback for milling, turning and grinding applications. The large-profile aluminium housing has an overall length of 870 mm. Circumferential sealing lips protect the glass scale and scanning carriage against chips, coolant spray and dust, while the IP 53 rating supports use under typical machine-tool conditions. The glass scale has a 20 μm graduation period and generates sinusoidal current signals with an output level of approximately ~11 μApp for compatible Heidenhain evaluation electronics and CNC controls. A single reference mark is located at 360 mm, the centre of the measuring length, enabling a reproducible reference run after the machine is switched on. Heidenhain 216750-BF uses mounting type R with a flexible right-hand end piece. Its elastic coupling compensates for small alignment errors between the encoder and the machine guide. Electrical connection is through a 9-pin type 34S09 connector and an integrated 0.30 m cable. Supply voltage is 5 V (±5 %). The housing weighs approximately 3.0 kg. The complete Heidenhain 216750-BF identification must match the installed system. The encoder is intended as a direct replacement for matching LS 703 systems on turning, milling and grinding machines. Available directly from our warehouse in Germany.

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.

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.
