Note 1: Resolution specification is only applicable to Orbit® digital transducers.The resolution of LVDT transducers is effectively                      infinite and is only limited by the conditioning electronics

 

Note 2: Cable Style A comprises of individual twisted cores, Style B comprises a sheathed and screened cable
 
 

 
 
 
 

Displacement Sensors | Miniature Displacement | MD Series

 

The small case diameter (6mm and 8mm) allows for easy installation in confined spaces. A right angle output facility is available as a retrofit for the 8mm version.The low core weight makes this range ideal for use in low inertia systems. Cross talk is prevented by the screened cable, which also allows for multiple use of these sensors in close proximity.

MD

The small case diameter (6mm and 8mm) allows for easy installation in confined spaces. A right angle output facility is available as a retrofit for the 8mm Version.

SM

SM transducers cover two standard linear ranges from ±1mm to ±3mm. They are designed for measuring displacement in applications where infinite resolution and repeatability are required in a very small size.
Digital Displacement sensor DO Thumb

OP

With a 9.5mm body diameter, the Optimum series of LVDT displacement transducers is the ideal choice for process control and research applications where space is limited.
