Rod Style LDT

953 VMax Series Linear Position Sensor

Linear Position Sensors play an important role in factory automation. Linear Position Sensors are also known as Linear displacement transducers, LDT, or simply as cylinder position sensors, these instruments secure the workflow on automated machinery or hydraulic cylinders

The Gemco 953 Series VMax Linear Displacement Transducer (LDT) is a linear position sensor developed to meet the most demanding processing challenges, regardless of application or operating environment.

The highly versatile VMax offers absolute accuracy and reliability with high resolution and precision repeatability. The VMax is resistant to contaminants and environmental conditions and is IP68 rated. Its rugged and durable mill duty construction exceeds competitive offerings, and its vibration resistance is lab tested at 30 Gs and shock resistance is lab tested at 1000 Gs.

This linear position sensor is easy to install and set up and features the latest generation of Magnetostrictive position-sensing technology with automatic gain circuitry. Custom configurations are available to meet specific end user requirements. The VMax family is an ideal cylinder position sensor with absolute feedback.

Models +
- 953A – Analog Output
  - The 953A VMax is an accurate, programmable zero & span, auto-tuning, non-contact linear position sensor in a rod-style package. The sensor utilizes our field-proven Magnetostrictive technology to give absolute position, accurate to 0.01% of the programmable sensing distance. A variety of analog voltage and current outputs are available. All units have a diagnostic LED to display the health of the unit and to help aid in troubleshooting. Our Analog units offer programmable Zero & Span points; the analog output is programmable over the entire active stroke length. Units can be ordered in span lengths from 1” (25mm) to 300” (7.6M).
- 953D – Digital Output
  - The 953D VMax is an accurate, programmable, auto-tuning, non-contact linear position sensor in a rod-style package. The sensor utilizes our field-proven Magnetostrictive technology to give absolute position, accurate to 0.01% of the sensing distance. A variety of digital outputs are available (Start/Stop, PWM & Control Pulse). All units have a diagnostic LED to display the health of the unit and to help aid in troubleshooting. Units can be ordered in span lengths from 1” (25mm) to 300” (7.6M).
