The PT9420 is a great value for demanding long-range applications requiring a 4 - 20 mA linear position feedback signal. Sealed to meet NEMA 4 standards, this Cable-Extension
Transducer will perform even under the harshest of environmental conditions.
As a member of our innovative family of NEMA-4 rated
cable-extension transducers, the PT9420 offers numerous
benefits. It installs in minutes, functions properly without
perfectly parallel alignment, and when its cable is retracted,
it measures only 6”.
100M ohms @ 100 VDC, min.

The output signal direction can be reversed at any time by simply
changing the dip-switch settings found on the internal signal board.
After the settings have been changed, adjustment of the Zero and
Span trimpots will be required to precisely match signal values to the
beginning and end points of the stroke.
Caution! Do Not Remove Spring-Side End Cover
Removing spring-side end cover could cause spring
to become unseated and permanently damaged.

VLS Option - Free Release Protection
The patented Celesco Velocity Limiting System
(VLS) is an option for PT9000 Series cable extension transducers that limits cable retraction to
a safe 40 to 55 inches per second for the single
spring option and 40 to 80 inches per second for
the higher tension dual spring option.
The VLS option prevents the measuring cable
from ever reaching a damaging velocity during
an accidental free release. This option is ideal for
mobile applications that require frequent cable
disconnection and reconnection. It prevents expensive unscheduled downtime due to accidental
cable mishandling or attachment failure.
