Product Description:

The HS35R2048H37C identified as a Sealed Hollowshaft Encoder made for vector duty applications. This device enables shaft installation that requires electrical insulation to 1.25 inches. The encoder provides durable operation in industrial applications while offering both long bearing service and adjustable connector types.

At 3600 RPM the HS35R2048H37C hollowshaft encoder functions with 80,000 hours of bearing life but it extends to 128,000 hours of life at 1800 RPM. The device provides two channel quadrature outputs (AB) and optional Z-index with complementary signals. Phase sense refers to the condition where channel A leads B on clockwise shaft rotation when observed from the shaft clamp end. This model’s quadrature phasing accuracy is maintained at 90° ±22.5° electrical while signal symmetry is controlled within 180° ±18° electrical. Shaft compatibility requirements include a radial runout of ± 0.025" along with axial ± 0.050" endplay. This encoder unit fits shaft sizes ranging from a minimum of 1.25" (32 mm) to a maximum of 2.0" (51 mm) with solid shafts recommended. Keyway shafts are accepted but flatted shafts should be avoided.

The HS35R2048H37C sealed hollowshaft encoder supports a wide range of mating connectors including 5 pin and 8 pin M12 and MS3106A series connectors in 6, 7 and 10 pin styles. It offers multiple configuration and accessory options for diverse setup needs. The compact size 35 hollowshaft format of this encoder supports easy mounting in tight installations. This model is electrically isolated from the shaft that reduces the risk of signal noise or grounding issues. It is designed to handle various application conditions without performance degradation. The sealed build of this model enhances protection against dust and moisture extending operational lifespan.
