LINEARITY - CONFORMITY
Limits of
linearity test
Effective electrical travel
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 ∆V max.
linearity / conformity = ± %
E
They are measured over 90% of actual electrical travel
(centered).
On request linearity can be guaranteed in linear law.
For example: linearity ± 2 % + J 145 option (see ordering pro-
cedure).

INTERLINEARITY - INTERCONFORMITY
It is the maximum deviation between the actual voltage out-
puts of 2 or more pot modules in the same assembly. It is ex-
pressed as a percentage of the total applied voltage, or pre-
ferably in dB attenuation.
Interlinearity is measured between 2 pot modules, over 10 to
90 % of the total electrical travel.
The interlinearity or interconformity is expressed as a percen-
tage of the total applied voltage :
ICI
I% = E
Or in decibels by comparison between outputs V1and V2
V1
I dB = 20 log V2
Here under (table 3) are the best
interlinearities between modules.
The first one is the reference.
Empty modules CV, screen modules
are understood as modules.

OPTIONS
MODULES: RS on/off SWITCH
RSI changeover SWITCH
The position of each module is free.
RS and RSI rotary switches are housed in a standard P11
module size 12,7 x 12,7 x 5,08 mm3(.5" x .5" x .2"). They have
the same terminal styles as the assembled electrical modules.
Switch actuation is described as seen from the shaft end.
D: means actuation in maximum CCW position
F: means actuation in maximum CW position
The switch actuation travel is 25° with a total mechanical tra-
vel of 300° ± 5°.
MODULES :
PUSH/PUSH SWITCH RSPP
MOMENTARY/PUSH SWITCH RSMP
The switches are manufactured by ITT, F.U. series (NE18
series available on request).
They have to be the last element of potentiometer and are lin-
ked to electrical module by an interface.
RSPP and RSMP switches are available only with P11/PA11
T-Q or 7 series not with P11/PA11 V or 2 series.
Options :
2 reversing switches F2 4 reversing switches F4
6 reversing switches F6 8 reversing switches F8
Available with shafts R(T), G (Q), CR (7) others shafts on
request.
Not available with panel sealed option.

RSD SINGLE POLE SWITCH, NORMALLY OPEN
In full CCW position, the contact between 1 and 3 is open. It
is made at the beginning of the travel in CW direction.
RSF SINGLE POLE SWITCH, NORMALLY OPEN
In full CW position, the contact between 1 and 3 is open. It is
made at the beginning of the travel in CCW direction.
RSID SINGLE POLE CHANGEOVER
In full CCW position, the contact is made between 3 and 2 and
open between 3 and 1. Switch actuation (CW direction)
reverses these positions.
RSIF SINGLE POLE CHANGEOVER
In full CW position, the contact is made between 1 and 2 and
open between 1 and 3. Switch actuation (CCW direction)
reverses these positions.
RSPP F2 : PUSH/PUSH SWITCH WITH TWO REVERSING
SWITCHES
Idle position : the contact is made between 1 and 2 and a and
b. It is open between 2 and 3 and b and c.
Pushed position: the contact is made between 2 and 3 and b
and c. It is open between 1 and 2 and a and b.
Not available on P11V and P11-2.
On request for P11Q and P11-7.
VALLEY DETENTS
The valley detents mechanism is housed in a standard P11
module. Up to 21 detents position available.
Count detents as follows : 1 for CCW position, 1 for full CW
position, plus the other positions forming equal resistance
increments (linear taper) - not equal angles.

SHAFTS (see ordering procedure)
The shaft lengths are always measured from the mounting
face.
Standard shafts are designed by a letter code (one or two
digits). Shafts slots are aligned to ±10° of the wiper position.
CONCENTRIC SHAFTS
The CC or 0 or 77 concentric shaft versions allies the total
flexibility of the P11/PA11 modular system to the advantage of
having two separate shafts.
The outer 6 mm or 1/4” or 1/8” dia. shaft drives the modules
situated immediately behing the panel, before the spacer
module.
The inner 3 mm or 1/8” or .07” dia. shaft drives the modules
situated after the spacer module.
Spacer is available with a choice of two spacer thickness :
5,08 mm designations : CC, 0, 77
2,54 mm designations : CC-3, 0-3, and 77-3. See page 2-59.
CUSTOM SHAFTS
When special shafts are required - flats, threaded ends, spe-
cial shaft lengths, etc. a drawing is required.
SPLINED SHAFT "I"
CENTER TAP "J"
The extra terminal is a solder lug connectedat 50% of elec-
trical travel and situated in the potentiometer module opposite
the terminals.
Center tap short circuit 11° of travel.
LONG LIFE APPLICATIONS 1 million cycles
P11 and PA11 single can be guaranteed for 1 000 000 mecha-
nical cycles order ref. J131.
TRIMMERS T11 - TA11
See data sheet No. 2.413.
NEUTRAL MODULE "EN"
Neutral or screen module is housed in a standard P11
module. It is used as a screen between two electrical modules.
The leads can be connected to ground.
LOCATING PEGS (Anti-rotation lugs)
The locating peg is provided by a plate mounted on the
bushing and positioned by the module sides.
Four set positions are available, clock face orientation : 12 3
69.
All P11 bushings have a double flat. When panel mounting
holes have been punched accordingly, an anti-rotation logs is
not necessary.
OPTION : ELECTRICAL MODULE ONLY
Application : positioning transducer.
Solution : single electrical module without shaft bushing
assembly.
Option : • 300° electrical travel (equal to mechanical travel)
• better linearity of variation law (taper).
Benefits : • economical
• for servo mounting, small dimensions allow use
in timy places or difficult of access.
