VLS/DA1 Series Optical Speed Sensors - With Analogue output
 
These VLS series Optical Sensors are primarily designed for data collection in speed related applications, ideal for use with all types of Datalogging equipment., both Laser and Non-Laser version are available including a range of optional mounting devices for hands free applications

Power input - Two options are available, the Laser model requires 7-15vdc @ 50Ma typically and the Standard MiniLamp version requires typically 5vdc @ 120mA.

Optical ranges - Up to 1 metre with MiniLamp and 2 metres with Laser version - using reflective tape.

Condition monitoring applications - models available for this requirement

Mains/battery pack
A suitable mains adaptor/battery pack is available type SIPP/1, for use with 5vdc VLS version ONLY.

Contact measurement - Both versions can be used with our Contact Adaptor range

Additional Information Signal Output
Power options
The Non-Laser 5vdc Sensor can be powered from any regulated DC supply or via our SIPP/1 rechargeable Power Pack. The Laser version requires a nominal 12vdc power source (7-15vdc)

Standard Sensors have a 1 metre captive cable and connector variations are shown in the price list Buy this Product section Other cable configurations available to order for OEM & volume applications.

 Analogue Output = 0 - 4vdc FSD for both measurement ranges

Contact adaptor
All versions can be used with LSAB-2 Contact Adaptor & LSAB-3 versions
