Voltage Divider - PT9101

• Range: 0-75 (190cm)
• 0-550 inches (1397cm)

The PT9101 is a work-horse for demanding long-range applications requiring linear position measurements. Available with either a 500, 1K, 5K, or 10K ohm potentiometer, the PT9101 operates with any basic panel meter or programmable controller.

4 ... 20mA - PT9420

• Range: 0-75 (190cm)
• 0-550 inches (1397cm)

The PT9420 is a great value for demanding long-range applications requiring a 4-20mA linear position feedback signal. Sealed to meet NEMA 4 standards, this Cable-Extension Transducer will perform even under the harshest of environmental conditions.

0 ... 10 VDC - PT9510

• Range: 0-75 (190cm)
• 0-550 inches (1397cm)

The PT9510 can operate from an unregulated 14.5 to 40 VDC power supply while providing a regulated output signal over its full extended range. It provides a 0-5 or 0-10 VDC position feedback signal proportional to the linear movement of its stainless steel measuring cable.

Incremental Encoder - PT9150

• Range: 0-75 (190cm)
• 0-550 inches (1397cm)

With its incremental optical encoder and industrial design, this rugged transducer provides the highest accuracy and longest life of any measurement device of its kind. This model is available in a wide variety of resolutions and output stages to fit virtually any requirement.

It can measure up to 550" (1397cm), yet when its cable is retracted, it is only 6" (15.24cm) long. Its small size and low-cost-to-measurement ratio offers remarkable flexibility and value.

Position/Velocity - PT9301

• Range: 0-75 (190cm)
• 0-550 inches (1397cm)

The PT9301 is a combination position and velocity transducer for demanding long-range applications requiring linear measurements. A precision plastic-hybrid potentiometer provides accurate position feedback while a self-generating DC tachometer provides a velocity signal that is proportional to the speed of the travelling stainless-steel measuring cable.

CANBus - PT9CN

• Range: 0-75 (190cm)
• 0-550 inches (1397cm)

The PT9CN communicates linear position feedback via the CANbus SAEJ1939 interface. The PT9CN has been designed for factory and harsh environment applications requiring full stroke ranges up to 550" (1397cm). 

DeviceNET - PT9DN

• Range: 0-75 (190cm)
• 0-550 inches (1397cm)

The PT9DN communicates via DeviceNET protocol with programmable controllers in factories and harsh environments requiring linear position measurements in ranges up to 550" (1397cm). 

RS232 - PT9232

• Range: 0-75 (190cm)
• 0-550 inches (1397cm)

The PT9232 delivers position feedback via RS232 serial communication to your data acquisition or controller system. The PT5232 sends a raw 16-bit position count from 0000 to FFFF (hex). Additionally this device can be set to continuously send data or send data only when polled.

As the internal position sensing element is a precision potentiometer, this transducer maintains current accurate position even during power loss and does not need to be reset to a “home” position. 

String Encoder - PT9600

• Range: 0-75 (190cm), 0-550 inches (1397cm)

The unique industrial-grade string encoder module mates to virtually any encoder, giving you a cost-effective linear position measurement solution that precisely fits your requirements. 

Velocity Limiting System  - VLS9000

Ranges: 0-75 (190cm), 0-1700 inches (4318cm)

• Prevents cable from ever reaching damaging velocity during a free release
• Ideal for applications requiring frequent connecting and disconnecting
• Provides safer operation for mobile applications
• Eliminates internal damage if a cable is broke

The 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 standard spring options and 40 to 80 inches per second for the higher spring tension options.

The VLS system 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. 

Redundant Brush System  - RBS9000

Ranges: 0-75 (190cm), 0-1700 inches (4318cm)

• Offers extra protection against extraordinary dirty environments.
• Reduces the cable exit opening down to a single point to prevent excess debris from entering the spool cavity.
• Uses two sets of cable brushes to help clean the measuring cable before it is retracted into the enclosure.

Designed for extreme applications where exceptional amounts of dirt, spray or some other foreign matter may enter through the standard PT9000 'slot opening' and interfere with the cable reel mechanism.

The RBS9000 reduces the cable opening down to a single-point exit to block most debris from entering the cable-reel area. Because some debris may get drawn into the transducer by the measuring cable upon retraction, we've taken two measures to help reduce that by:

• Each RBS9000 is constructed using nylon-coated measuring cable which has as smooth layer of protection that helps keep debris from clinging to it.
• The measuring cable passes through two integral brushes which help wipe away any matter that may be clinging to it.
