HARSH-DUTY OPTICAL ENCODERS

Danaher Industrial Controls Group (DICG) announced an expansion of its NorthStar brand of heavy duty encoders with a new line of harsh-duty optical encoders designed for washdown and intrinsically safe environments. The new line's five encoder models -the HD20, HD25, HSD23, HSD38 and DWD38 - are the first optical products in the NorthStar brand. A double-labyrinth sealed housing enables the encoders to achieve ratings of IP66/IP67 and NEMA 4X or NEMA 6.

All of the encoders are available with optional stainless steel or nickel plated housings. An opto ASIC with innovative packaging techniques enables the encoders to operate in high shock vibration environments.
Units are rated for mechanical shock of 50 G for 11 ms duration, and vibration of 5 to 2000 Hz at 20 G. Intrinsically-safe versions are available certified to ATEX EEx ia IIB T4, when used with the appropriate IS barrier. Intrinsically-safe model encoders are rated to 80°C.
