Product description

The Heidenhain 605374-92 is a sealed incremental linear scale from the LS 477 series with a measuring length of 1020 mm. The system operates according to the photoelectric scanning principle on a DIADUR glass scale with a grating period of 20 μm. The integrated 50-fold interpolation produces a signal period of 0.4 μm and supports measurement steps of 0.1 μm with 4-fold evaluation in the downstream electronics. The Heidenhain 605374-92 provides an accuracy of ±5 μm over the entire measuring length — suitable for use in numerically controlled machine tools, grinding and milling centres and boring mills. The output signal is TTL-compatible (A+, A−, B+, B−, R+, R−) with selectable reference marks in the 50-mm grid. For the ML range up to 1020 mm two reference marks are provided, each 35 mm from the beginning or end of the measuring length. The scale operates from 5 V ±5 % and has a no-load current consumption of less than 140 mA. A separate adapter cable (1 m, 3 m, 6 m or 9 m) connects the scale to the terminal block; cable lengths up to 100 m are permitted with Heidenhain cable. With a maximum travel speed of 48 m/min and an shock resistance of up to 300 m/s² (IEC 60068-2-27) the device is designed for demanding machine environments. The protection rating is IP 53 when installed as intended, or IP 64 when used with the DA 300 sealing-air unit. The operating temperature range extends from 0 °C up to +50 °C. Directly available from our warehouse in Germany.

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.
