Clearance

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 to 10 Vdc (LD621).

An unusually large bore-to-core clearance is maintained throughout the range. This makes installation easier and helps prevent misalignment.
