Product Specs

The LD620 series has been replaced by the new and improved LD600A series. Many ranges are in stock, available for immediate shipment. Link "LD600A Series" in redirected to the LD600A page LD621A-100

The LD620 DC output displacement tranducers have improved IP67- rated sealing, coupled with new polymer guides with rigid carriers. These transducers are accurate and reliable, especially in wet and corrosive conditions. Output options are either ±5 Vdc (LD620) or 0-10 Vdc (LD621). An unusually large bore-to-core clearance is maintained throughout the range. This makes installation easier and helps prevent misalignment on automation actuators and other industrial automation controls.

I have a LD621-15 that I'm using to test Frequency Response of a Hydraulic actuator. I would like to knot what kind of latency (in Seconds or Fractions of a second) there is in the internal electronics of the output signal?

Asked by: MLW58
Thank you for you inquiry. Unfortunately there is no data available on the lag between movement to the rod and signal response of the LD621

Is this model spring-loaded? If so, in which direction (i.e. does it always try to stay extended, or retracted)?

Asked by: JDwight
Yes it is spring-loaded in the extended position
