2 <2000 m/s for 6 msSee the following frequency table (sensor lines available, see page 27) PUR jacket, high flexibility, dmr. 5.3 mm, 5(2 x 0.05) + 1 (2 x 0.14) mm²(Bending radius: 10 x d = 50 mm continuous bending; 5 x d = 25 mm single bend)
2 ! Output analog 1 Vpp: WMK-111. At the output, the system delivers the same number of sinusoidal periods as grating pitches (N) on the measuring flange, or can provide a multiple of this where the period is divided by the factor D.Basic period 1000 µm arc length. Possible dividing factors D = 1 / 4 / 8 / 10 / 25 / 32 Total number of sinusoidal periods at the output: N’ = N x D (e.g.: for a measuring flange with 512 grating pitches, where a dividing factor of D = 32 is used, the output provides N’ = 512 x 32 = 16384 sinusoidal periods per revolution)
(see diagram on page 26) ! Output TTL (RS422): WMK-112. Resolutions of: 62.5µm / 50µm / 31.25µm / 25µm / 10µm / 5µm / 1µm / 0.25µm(Arc length after 4x edge evaluation) See the following frequency table LED on the connector housing as an assembly aid (by request)
