Linear Incremental Encoder
The LN series provides 5-28 V differential quadrature outputs for a wide range of motion control applications
IP 67 Rated
The BEI linear encoder combines the advan- tages of inductive sensing with the versatility of differ-
ential quadrature outputs. Its design includes a sealed stainless steel scale and a potted read head for an IP67 environmental rating, allowing it to oper-
ate even while submerged. This rugged construction gives the LN encoder shock and vibration tolerances far surpassing those of glass scales. Harnessing the power of digital
signal processing (DSP) technology, the LN provides industry standard differential quad- rature outputs in 5 to 28 VDC line driver, 5 volt regu-
lated or open collector style outputs at traverse rates nearly twice that of
typical linear encoders. Repeatable to ± 1
count and available in
resolutions as fine as 0.5µm, the LN encoder is a tough, dependable and highly adapt- able solution to a wide variety of positioning challenges. Applications include process control, robotics and pick-and-place operations.
