2 open-collector quadature outputs
shaft dimensions 6mm Dia, 13mm Length
outer dimensions approx. 38mm Dia, 35.5mm Length
industrial quality
1m screened cable
Demonstration only. Only the encoder is for sale. Design notes: The quadrature outputs are
open-collector, so can be interfaced to 3V3 or 5V logic. Pull-up
resistors will be required. With some microprocessors, these can be
on-chip, enabled in software. Because of the high resolution of
the decoder, your software will need to be able to cope with high pulse
frequencies and small tuning steps. Our demo in the video uses edge
detection (1600/rev) using interrupts and
1Hz tuning steps on an Arduino Mini Pro clone. This gives 1.6kHz per
revolution. Simply substituting for a cheap contact-based decoder
without changing the software may not give good results. Sample code

mounting requires a 20mm hole and three M3 screws (included). Pin-out
marked on each encoder. Case and markings (but not functionality) may
vary slightly as availability dictates. Fair postage. Proof of posting obtained for all shipments. No packing charges. Orders received before 3 p.m. are normally posted on the same day (Mon-Fri).
