1. VLR Encoders Introduction
Designed to meet the requirements of the most demanding applications
The VLR series of Electric Encoders™ are a line of encoders designed to meet the needs of various industries,
especially in extreme environments from defense to heavy machinery.
The VLR series is engineered for high durability, It is a non-contact, low-maintenance, and easy-to-install
solution. The capacitive technology ensures dependable performance, which is crucial for industries that
operate under tough conditions.
These encoders are based on capacitive technology developed and improved for over 20 years by Netzer
Precision Position Sensors.
The VLR encoders are characterized by the following features that sets them apart from
other similar encoders:
●Low profile (<12.5 mm)
●Hollow shaft (Stator / Rotor)
●No bearings or other contact elements
●High resolution and excellent precision
●Immunity to magnetic fields
●High reliability in extreme environments
●Durability and ease of installation
●High tolerance to temperature extremes, shock, moisture, EMI, RFI
●Holistic signal generation and sensing
●Digital interfaces for absolute position
The holistic structure of the VLR Electric Encoder™ makes it unique. Its output reading is the averaged outcome
of the entire circumference area of the rotor. This inherent design characteristic provides the VLR encoder with
outstanding precision as well as a tolerant mechanical mounting.
The absence of components such as ball bearings, flexible couplers, glass discs, light sources & detectors, along
with very low power consumption, enables the VLR encoders to deliver virtually failure-free performance.
