HeidenhainROD 426 5000 02S12-03Incremental Rotary Encoder with Integral Bearing, 5000 Lines, TTL 5 V, 6 mm Solid Shaft, M23 12-Pin, IP67

Product Description

What this part is:

Heidenhain ROD 426 incremental rotary encoder with integral bearing, 5000 lines per revolution, TTL interface. Rotation of the shaft produces two square-wave channels in quadrature plus a once-per-revolution reference mark. 6 mm solid shaft for a separate shaft coupling, synchro flange, M23 12-pin flange socket. Quantity: 1 Pc.

Decoding the designation:

ROD — incremental rotary encoder with integral bearing and solid shaft for a separate shaft coupling.

426 — the TTL member of the ROD 400 family.

5000 — line count, 5000 signal periods per revolution.

S12 — M23 12-pin flange socket electrical connection.

376846-03 — Heidenhain ID number, also marked 376-846-03 on the unit.
