VLS
Optical Speed Sensors with NPN Pulse or Analog Output
VLS Series Optical Speed Sensors - Standard Models
The VLS series of Visible Light Optical Sensors is primarily designed for speed related use. Ideal for use with our range of Digital Tachometers, including hand held, panel mounted and bench style instruments. A range of mounting devices is available for hands free applications.

Condition monitoring applications
There are 2 versions with on/off switch fitted so that battery power is conserved when used with battery powered equipment.

Mains/battery pack
A suitable mains adaptor/battery pack is available for use with all 5vdc VLS versions.

Optical ranges
Up to 1 metre for visible light versions and up to 2 metres with the Laser light types (with reflective tape).

High speed applications
A clip on prefocussed adaptor lens (LN1) is available which can allow operation without reflective tape in certain controlled conditions.

Power options
These sensors are available in 5vdc and 7.5- 40vdc powered options, normally provided by the associated instrument from our range.

Contact Adaptor
The contact adaptor converts the optical function into direct shaft contactor for both RPM and linear speed measurement. This bayonet fitting device operates via a Hall Effect magnetic sensor built into the Sensor housing which picks up from a magnet in the VLS sensor.

VLS/DA1 Optical Speed Sensor with Analogue output
The new VLS/DA1 Optical Sensor with integral Digital/Analogue convertor, is designed for datalogging applications and where general speed monitoring of machines is required. It is particularly useful for monitoring & recording speed data. The VLS/DA1 is designed for use with Datalogging and Condition monitoring equipment.
