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

ΔV 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)
