Dunkermotoren RE20 Incremental Encoder
The Dunkermotoren RE 20 is a compact incremental encoder that works contact-free, so there are no brushes or contact surfaces to wear out in continuous-duty applications. It delivers 100 ppr (400 cpr) through an A/B interface from a 5 Vdc supply, with 24 V versions available on request. The RE 20 is compatible with the GR 42, GR 53, GR 63, GR 80...
Read MoreThe Dunkermotoren RE 20 is a compact incremental encoder that works contact-free, so there are no brushes or contact surfaces to wear out in continuous-duty applications. It delivers 100 ppr (400 cpr) through an A/B interface from a 5 Vdc supply, with 24 V versions available on request. The RE 20 is compatible with the GR 42, GR 53, GR 63, GR 80 and BG 62 dCore motor series.
Standard protection is IP 30, rising to IP 65 when the encoder is integrated in the BG motor profile housing. For cable runs longer than 2.5 m between encoder and control, Dunkermotoren recommends an encoder with a driver (TI) stage.

Features
- Contact-free magnetic sensing — no brushes or wear parts, so feedback stays reliable in continuous duty
- 100 ppr resolves to 400 counts per revolution in quadrature, giving dependable speed and direction sensing for closed-loop control
- 15 ns rise and fall times keep signal edges clean at speed, so the controller doesn't drop counts
- Runs from the same 5 Vdc rail as most control electronics — no dedicated supply needed (24 V on request)
- IP 30 open-mounted or IP 65 inside the BG profile housing — one encoder suits both clean and harsher installations
- Compact Ø 44 mm × 18.5 mm body fits tight machine envelopes without redesigning the drive end
