BEI Sensors HS35 Series Incremental Optical Encoders
BEI Sensors / Sensata HS35 Series Incremental Optical Encoders feature a hollow shaft design that accommodates shafts up to 1" in diameter and supports either through-shaft or blind shaft mounting configurations. The design details include dual bearings with integrated shaft seals, adjustable insulating inserts for smaller shafts, and compliance with NEMA 4, NEMA 13, and IP65 environmental ratings. These devices produce 2 channels in quadrature with a 1/2 cycle index output, offering dual resolution options and supporting up to 80,000 cycles per revolution. The HS35 series has a supply voltage range from 5VDC to 28VDC, a frequency response of 150 kHz, and an operating temperature range from 0° to +70°C with extended options. These encoders are used in applications such as motor feedback systems, vector control, printing machinery, robotic control, and web process control.

I’m a bit of a DIYer, and I’ve gotten pretty good at eyeballing things. That’s worked for me, but you need precision and reliability with things like oil rigs and robotic controls. Sensata’s HS35 Incremental Optical Encoders provide reliable feedback in the harshest applications. For hazardous location applications, intrinsically safe and nonincendive options are available. These innovative devices use a hollow shaft design in a rugged metal housing that integrates heavy-duty features typically seen on shafted encoders. The HS35 can accommodate shafts up to 1” in diameter, has dual high-carbon steel bearings, and includes shaft seals for NEMA 4, 13, and IP65 ratings, and a sealed connector or cable gland - all standard features. Sensata’s HS35 can be configured from 1 to 80,000 cycles per shaft turn. They’re also offered with dual outputs that can be used for redundancy, dual resolutions, or to supply data to two separate controllers.
