HS35 ABSOLUTE ENCODER

Product Description

Built on the same rugged design as the incremental model, the HS35 Absolute Encoder is available with various output options including Gray Code and

Natural Binary. Designed with a cast aluminum housing, a sealed connector and shaft seals, it carries an IP65 environmental rating. With the optional

insulating inserts, it can be mounted on smaller diameter shafts. It is designed for either a through shaft mounting or blind shaft mounting with a closed

cover to maintain its environmental rating.

Direction of Count: Standard is CW increasing when viewed from the shaft end. Pin R is normally HI (or N/C) and is pulled up internally to +V. To reverse the count

direction, Pin R must be pulled LO (COMMON).

Latch Control: Encoder outputs are active and provide continuous parallel position information when Pin U is HI (or N/C). Pin U is pulled up internally to +V. When

Pin U is LO (COMMON) the encoder outputs are latched at the logic state that is present when the latch is applied and will stay latched until Pin U is no longer LO

(COMMON).

M18 Connector is a MS3102R18-1P, 10-pin connector on the encoder body and mates to an MS3106F18-1S connector or can be used with a standard cable/connec-

tor assembly, BEI P/N 924-31186-18XX (Where XX = 10, 20 30 or 50 for a 10, 20, 30, or 50 foot length). This is the preferred connector for SSI output.

M14/19 Connector is a MS3112E14-19P, 19-pin connector on the encoder body and mates to an MS3116J14-19S or equivalent.

1. 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.

2. 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

13-28VDC: For Analog

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). Note: Limit encoder load to 2.5W max at ambient. Example at 12 VDC: 2.5W/(+12VDC minus +5VDC) =

357 mA total allowed current. Consult factory for your specific requirements.

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.

3. 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.

* Products manufactured prior to April 2007 used the line driver IC number instead of voltage output in model number.
