The LD320A Series of linear displacement transducers is the perfect combination of high accuracy and ruggedness to suit most general purpose applications. Not only do these products have up to 0.25% linearity, but they are also rated IP67 with a 304 stainless steel case that is hermetically sealed.

Rated 1 out of 5 by from Very unclear what you are buying There is no manual or datasheet provided for this product. The core has a rod end, but the core is unguided. This mounting configuration doesn't make sense unless the core is intended to rub on the inside of the coil body. Provided Test report lists the supply voltage as "Source (VDC): 24", and the output is in V .But this is an AC lvdt so the source should be 3 Vrms, 3kHz. Report also only goes from 0mm to 50mm, should be -50mm to 50 mm. The part length does not match the table on the webpage. -50 to 50 mm length is listed as 8.23", but is actually 11.5" (The length of the -100 to 100 mm) model. The harness and test report say 0-50mm, but unit should be -50 to 50 mm.

If the range is +/- 50 mm, shouldn't the B dimension be at least 100 mm at full extension?

Asked by: Elliot
Yes. The full extended rod dimension should actually be somewhat longer than 100 millimeters. We will look into this error and have the dimensions on the product page corrected.
