Incremental Encoders HSD25
Incremental Encoders ISD25

The intrinsically safe optical ATEX hollow shaft encoder ISD25 with a shaft diameter of up to 19.05 mm works reliably in the temperature range from -40 ° C to +100 ° C. This type of encoder with a hard-anodized housing design exceeds the requirements of protection class IP66 / IP67 and NEMA 6. By using the latest OptoASIC technology, the encoder is insensitive to shock and vibration. The rotary encoder type HSD25 can be easily installed on the motor and thus enables reliable feedback signals under rough ambient conditions.

This robust encoder is also available in Stainless Steel to meet NEMA 4x and 6P requirements and its sealed housing allows the Encoder to be operated when regulatory washdown and high pressure steam or caustic chemicals are required. Utilization of an advanced Opto ASIC with innovative packaging techniques enables the encoder to operate in high shock and vibration environments. The ISD25 is also available in an Intrinsically Safe version certified to ATEX EEx ia IIB T4 when used with the appropriate IS barrier.
