M08: Code for the double potentiometer. (3) BUSHINGS The codes types 11, 12 and 13 have an antirotation lug (at 90CW). Plastic shaft and double model are only available with 6 bushing. (4) VALUE: Code: 10 1 Number of zeros 2 first digits of the value. In models and with different values, order under special drawing number. Example : +7% Code : (5) Tolerance (special), upon request. 07 05 negative tolerance -5% positive tolerance (6) Shafts special length: M06 ....... 24.5 Only for special length and plain shafts (not knurled). Example: Shaft 6 L= 24.5 special length Flatted and slotted shafts, etc. will need drawing. shafts Shaft M08 (T-21D) with other length, order under special drawing number. Recomendation : Shaft L > 60 ..... bushing C = 19 (7) DETENTS : - Not available in models with plastic shaft X, W, Y, Z. - Detents and switch are not compatible. (8) Stereo matching: Only available in tandem models and upon request. (9) SWITCHES : Two types of switches are offered: F1 and F2. F1 = The code isF01 Plastic shafts are only available if they are code P10, P11 or P12 F2 = (Only with metal shaft) Indicate the corresponding I-21 switch code. (10) Switch option not available with antilog taper.
