Macro Sensors Unveils CD 375 Miniature LVDT Position Sensors for Linear Position Measurements

Robots and robotic arms depend on sensors to measure the force or motion of an object. Enabling robots to detect changes in position, Macro Sensors has developed the miniature LVDT linear position sensor, which is attached to the robotic arm.

The sensor sends analog voltage signal relative to the movement, to a controller capable of making required adjustments.

The controller can make the robotic arm to slow down or stop its function based on the information received from the position sensor. For instance, on a pick and place machine, if the robotic arm travels more than the required distance, the miniature position sensors evaluate the movement for maximized performance and sends it back to its destination.

The CD 375 miniature LVDT series from Macro Sensors can be used on industrial robots and can also be applied in servo valves, hydraulic actuators and medical equipment. Measuring only 3/8 of an inch in diameter with a low mass lightweight core, the tiny touchless position sensors can be used in copy machines, ATMs, automatic inspection equipment and plastic injection molding machines that require high dynamic response.


Available with a measurement range between +/-0.025" and +/-2.0", the AC operated LVDTs provide 50% more core-to-bore radial clearance, which is greater than competitive units.

The CD 375 series feature high resolution, lower repeatability error and higher sensitivity constant with good linearity. With operating temperatures ranging between -55°C and +105°C (-65°F and +220°F), epoxy encapsulation and stainless steel housings shield the units in hostile environmental conditions. The external sealing of the sensor meets IEC standard IP-61.
