Scale Model – Scale Mounting
Lxxx or Rxxxx
For Linear Scales:
T = Tape Mounting
C1 = 3 scale clamps*
C2 = 10 scale clamps**
Hubs for Rotary Scales:
NH = No hub
HE = for R1206
HA = for R1910
HB = for R3213
HC = for R5725
HD = for R10851
M1504P = 4x interpolation
M1508P = 8x
M1520P = 20x
M1540P = 40x
* 3 clamps come standard with linear scales up to 130mm
** 10 clamps come standard with linear scales 155mm or longer
