The LD620 series has been replaced by the new and improved LD600A series.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.
