| MODEL HS35 INCREMENTAL OPTICAL ENCODER Introduction The HS35 combines the rugged, heavy-duty features usually associated with shafted encoders into a hollow shaft style. Its design includes dual bearings and shaft seals for NEMA 4, 13 and IP65 environmental ratings, a rugged metal housing, and a sealed connector or cable gland. The HS35 accommodates shafts up to 1” in diameter. With optional insulating inserts, it can be mounted on smaller diameter shafts. It can be mounted on a through shaft or a blind shaft with a closed cover to maintain its environmental rating. The HS35 is also available with a dual output option (inset) to provide redundant encoder signals, dual resolutions, or to supply two separate controllers from a single encoder. Applications include motor feedback and vector control, printing industries, robotic control, oil service industries, and web process control.

The typical hollow shaft product is supported by, and clamped to, the driving shaft. A flexible tether is used to keep the housing from rotating. 2.The rubber shaft seal is recommended in virtually all installations. The most common exceptions are applications requiring a very low starting torque or those requiring operation at both high temperature and high speed. For these exceptions, a felt shaft seal is recommended. Felt seals require very low starting torque and can virtually eliminate frictional heat. Encoders ordered with felt shaft seals will have an enclosure rating of IP50 and will have less than 1/10th the Starting Torque specified under Mechanical Configurations. 3. Non-standard index widths and multiple indices are available by special order. Consult factory. 4. Complementary outputs are recommended for use with line driver type (source/sink) outputs. When used with differential receivers, this combination provides a high degree of noise immunity. 5. Output IC’s: Output IC’s are available as either Line Driver (LD) or NPN Open Collector (OC) types. Open Collectors require pull-up resistors, resulting in higher output source impedance (sink impedance is similar to that of line drivers). In general, use of a Line Driver style output is recommended. Line Drivers source or sink current and their lower impedance mean better noise immunity and faster switching times. Warning: Do not connect any line driver outputs directly to circuit common/OV, which may damage the driver. Unused outputs should be isolated and left floating. Our applications specialists would be pleased to discuss your system requirements and the compatibility of your receiving electronics with Line Driver type outputs. 28V/V: Multi-Voltage Line Driver (7272*): 100 mA source/sink. Input voltage 5 to 28 VDC ± 5% standard (Note: Vout = Vin). This driver is TTL compatible when used with 5 volt supply. Supply lines are protected against overvoltage to 60 volts and reverse voltage. Outputs are short circuit protected for one minute. Supply current is 120 mA typical (plus load current). This is the recommended replacement for 3904R and 7406R open collector outputs with internal pullup resistors. It is also a direct replacement for any 4469, 88C30, 8830 or 26LS31 line driver 28V/5: Multi-voltage Line Driver (7272*): 100 mA source/sink. Input voltage 5 to 28 VDC +/- 5% standard, internally regulated with 5V (TTL compatible) logic out. Supply lines are protected against overvoltage to 60 volts and reverse voltage. Outputs are short circuit protected for one minute. Supply current is 90 mA typical (plus load current). 28V/OC: NPN Open Collector (3904*, 7273*). Current sink of 80 mA max. Current sourced by external pull- up resistor. Output can be pulled up to voltage other than supply voltage (30 V max). Input voltage 5 to 28 VDC ± 5% standard. Supply current is 120 mA typical. This replaces prior IC’s with designations of 3904, 7406, 3302, 681 and 689. 5V/OCR, 15V/OCR, 24V/OCR: Open Collector (3904R*, 7406R*, 7273R*): Current sink of 70 mA max. Includes internal pull-ups sized at approximately 100 ohms/volt. Max current source is 10 mA. Supply current is 100 mA typical, 120 mA with internal pull-ups. The 5V/OCR, 15V/OCR and 24V/OCR are often replaced by the 28V/V in system upgrades. Intrinsically Safe Voltage/Output options: 5V/V, 5V/OC, 5V/OCR, 9V/OC are the only output options available with the Intrinsically Safe “EX” Hazardous Area Rating model option. They must be installed per Control Drawing 08292-001. 6. Special –S at the end of the model number is used to define a variety of non-standard features such as special shaft lengths, voltage options, or special testing. Please consult the factory to discuss your special requirements. 7. Higher frequency response may be available. Please consult with the factory. 8. Extended temperature ratings are available in the following ranges: -40 to 70°C, -40 to 85°C, –20 to 105°C and –40 to 105°C depending on the particular model. Some models can operate down to -55°C. Extended temperature ranges can affect other performance factors. Consult with factory for more specific information. 9. Mating straight plug receptacles may be ordered from the factory: For M12 use MS3116F12-10S For M14 use MS3106F14S-6S For M14/19 use MS3116J14-19S For M16 use MS3106F16S-1S For M18 use MS3106F18-1S For M20 use MS3106F20-29S Page 7 Copyright © 2020 Sensata Technologies, Inc. www.sensata.com AGENCY APPROVALS & CERTIFICATIONS Model HS35 Hazardous Area Ratings Agency Blank EX Intrinsic Safety NI Non-Incendive Ratings and Markings File Number CE EN 55011: Electromagnetic Disturbance (EMI) EN 61000-6-2: Electromagnetic Compatibility (EMC) UL Class I, Groups A, B, C, D Class II, Groups E, F, G 20180302-E78446 DEMKO II 1 G Ex ia IIC T4 Ga (9V/OC is II 1 G Ex ia IIB T4 Ga) DEMKO 06 ATEX 0614247X IEC/IECEx Ex ia IIC T4 Ga (9V/OC is Ex ia IIB T4 Ga) -40°C ≤ Ta ≤ +85°C IECEx UL 12.0035X UL Class I, Div. 2, Groups A, B, C, D Class II, Div. 2, Groups F, G 20170321-E78446 DEMKO II 3 G Ex nA IIB T3 Gc DEMKO 13 ATEX 1209038X IEC/IECEx Ex nA IIB T3 Gc -40°C ≤ Ta ≤ +85°C IECEx UL 13.0071X Page 8 Sensata Technologies, Inc.
