P11 OPTION: CENTER CURRENT TAP “J”

The extra terminal is a solder lug connected at 50 % of electrical

travel and siluated in the potentiometer module opposite the

terminals.

Center tap presents a short circuit of 11° of travel.

• Sealing IP60

Center tap

P11 OPTION: SPECIAL LINEARITY - CONFORMITY

The independent linearity (conformity for the non-linear laws) is

the maximum gap

V between the actual variation curve and

the theorical variation curve the nearest to it. The linearity and

the conformity are expressed in percentage of the total applied

voltage E



They are measured over 90 % of actual electrical travel

(centered).

On request linearity can be guaranteed in linear taper.

ORDERING INFORMATION (First order only)

J123

Independent linearity ± 3 % (linear law)



J145

Independent linearity ± 2 % (linear law)

For other request, contact us.

P11 OPTION: SPECIAL INTERLINEARITY - INTERCONFORMITY

It is the maximum deviation between the actual voltage outputs

of 2 or more pot modules in the same assembly. It is expressed

as a percentage of the total applied voltage, or in dB

attenuation.

Interlinearity is measured between 2 pot modules, over 20 to

90 % of the attenuation.

The interlinearity or interconformity is expressed as a

percentage of the total applied voltage:

Or in decibels by comparison between outputs V1 and V2



ORDERING INFORMATION (First order only)

J44

Interlinearity ± 2 % (linear taper)
