LD701 SERIES

Non-Contact Linear Displacement Sensors

INSTRUCTION

SHEET

GENERAL DESCRIPTION

Non-contact linear sensors have an analog output that is proportional to the damping targ e t .
Their compact yet sturdy design makes them well suited for industrial, robotics and laboratory use.

These sensors utilize inductive technology, which means they are capable of sensing any metal
t a rget. The sensing distance, however, is influenced by the metal target. Ranges are calibrated
using a standard square target. The target is mild steel (Fe 360), 1mm (0.04”) thick. The side
lengths are the larger of either the sensor’s face diameter or three times the sensing distance.

Sensing distances are influenced by diff e rent metals other than mild steel. The Correction Factor
chart, shows the reduction that occurs when brass or other target metals are used. For example, if
the target were brass, the LD701-1/2 would sense 0.5 to 1.0mm (0.02 to 0.04 in).

The voltage output generated is directly linear to the distance being measured. The output can be read
by panel meters, recorders, computer boards or dataloggers, all of which are available from OMEGA.
