Hengstler Incremental Encoder HD 20

Hengstler Incremental Encoder HD 20 | Descriptions

The optical HD20 incremental rotary encoder is a compact unit for high demands that exceed the requirements of IP66/IP67 and NEMA 6. Available with stainless steel housings, these rotary encoders are ideal for tough ambient conditions that require excellent resistance to high-pressure cleaners and corrosive chemicals. Large-sized bearings are designed to withstand high axial and radial forces up to 440 N. The HD20 series of rotary encoders also includes intrinsically safe ATEX variants for use in potentially explosive atmospheres.

The HD20 Harsh-Duty Optical Encoder is a compact heavy-duty encoder designed to exceed IP66/IP67 and NEMA 6 enclosure requirements. It is also available in stainless steel that exceeds NEMA 4X and NEMA 6P requirements and is ideal for stringent washdown environments, including those where high-pressure steam or caustic chemicals are needed to meet regulatory requirements.

The HD20 features a max. 440N Axial and Radial Bearings, -40° to +100°C temperature range and unique labyrinth double-sealed housing, and optional dual "redundant" outputs and is covered by a two-year warranty (one year for bearings). NorthStar's traditional quality, reliability and value are built-in to every HD20 encoder. Also available in this series, is an Intrinsically Safe version certified to ATEX EEx ia IIB T4 when used with the appropriate IS Barrier. Accessory barriers can be supplied with the encoder.
