Low-Profile Precision Rotary
Sensor Module
9850
Generation II Benefits:
Gen II
Series
The 9850 Gen II Series offers a highly reliable rotary
potentiometer sensor module that can be easily integrated
into a wide variety of space-conscious applications requiring
installation simplicity, long service life and repeatable accu-
racy. The 9850 Gen II Series introduces a new, lower profile
(15.2mm; maximum connector receptacle height 25.9mm),
designed to perform in demanding environments.
Manufactured for optimal cost-economies, the 9850
Gen II Series offers simple yet durable design strengths
that can lead to significant systems costs savings. Plug-in
simplicity and sealed connector contact is assured via an
integral right-angle connector receptacle designed to
accept industry-standard Packard Electric METRI-Pack
™
connectors. This design also eliminates weak/stress points
and leaks in exposure to water.
Twelve standard models offer a choice of 180° or 120°
mechanical rotation with round or slotted mounting holes
for optimal installation alignment.
• Dual-output offers the added functionality of
two sensors in a single sensor
• Sealed integral interface accepts industry-standard
Packard Electric METRI-Pack
™
connectors
