EGR (EXHAUST GAS RECIRCULATION)
VALVE POSITION SENSOR |
| A
unique approach to high volume production
was achieved by direct screening the conductive
plastic element on a wafer thin polyimide
substrate. Mounted on a glass laminate base
for mechanical strength, these units display
good linearity without benefit of additional
trimming. Low in cost in large quantities,
these elements have long dither life applications
and can be supplied with wiper assemblies
for most effective "mating." |

The
element of this particular model is designed
to withstand extra-ordinary long dither life
on the order of 25x107
cycles over stroke lengths up to .010 in.
Capable of dissipating 0.9 watts at 120°C,
derated to zero at 150°C. The resistive
element is screened on a polymide laminate
and can be supplied with a variety of standard
wiper assemblies. Existing manufacturing facilities
are capable of producing these units in high
volume at low cost. |

GYROSCOPIC
GIMBAL TRANSDUCER |
| Designed
to be optimized for dithering application
in gyroscopic gimbal assembly of an infrared
seeker head. A direct screened resistance
element on a polyimide substrate. The mating
wiper assembly is configured to allow for
low torque and low inertia. Tinned metal solder
eyelets are provided for leadwire terminations.
Lon-life characteristics in a dither condition
is primary to these units. |

DUNCAN
SERIES 400 SLIDELINE |
|
Designed
for varied applications throughout the audio,
broadcast, lighting and sound reinforcement
industries. Specific applications range
from video control switchers, sound reinforcement
and recording/broadcast consoles to lighting
control consoles, musical instruments and
synthesizers.
Offered
in two stroke lengths - 2-3/4" and 4-1/4"
travel, the unique features include narrow
width, low profile, linear and audio outputs
and single or dual channels. They have cases
of durable, solvent-resistant plastic with
a built in moisture and dust seal.
The
element, conductive plastic, is well known
for its low noise and long life characteristics.
It has a ten-year reliability record in
the audio/broadcast field. Typical field
reports show operational life exceeding
50 million cycles with no degradation.
