EVDEVD Series Draw Wire Mechanics (EVD2000MB – EVD20000MB)

EVD Draw-Wire Mechanics for Encoders

EVD draw wire mechanics convert linear travel into rotation of an encoder shaft: a coated steel wire rope winds onto a measuring drum and a return spring keeps it taut. Eight versions cover 2–20 m, with 200 mm (2–3 m) or 333.334 mm (5–20 m) of wire per drum revolution, 0.05 % FS linearity and 0.01 % repeatability. High-strength aluminium alloy housing, −25…+85 °C. The unit mounts onto an encoder with a B6 flange (synchro flange, Ø 6 mm shaft), e.g. EAC58B6 or EAM58B6; resolution and interface are set by the chosen encoder.

Measuring range: 2, 3, 5, 6, 8, 10, 15, 20 m (EVD2000MB … EVD20000MB)
Wire travel per drum revolution: 200 mm (2–3 m), 333.334 mm (5–20 m); resolution = travel per revolution ÷ encoder ppr
Linearity / repeatability: 0.05 % FS / 0.01 %
Wire rope: coated steel, Ø 1.3 mm (2–3 m), Ø 1.5 mm (5–20 m)
Spring force: 8 N / 10 N
Max. wire speed: 15000 mm/s
Encoder mounting: B6 flange (synchro flange, Ø 6 mm shaft), e.g. EAC58B6, EAM58B6
Housing and temperature: high-strength aluminium alloy, silicone dust cover at wire outlet; −25…+85 °C
