The compact hollow-shaft incremental encoder in rugged all-metal die-cast housing with a hollow shaft for monitoring speed or position in drive systems, especially for AC motors

HÜBNER / SIEI America Incremental Encoders (Digital- Tachos) have over the years become standard in many areas of the industry due to their rugged construction adapted to the application

(Heavy Duty Technology):

Sensing by opto-ASIC, compensated for temperature and aging
Electromagnetic Compatibility (EMC) according to IEC 801-4
High vibration and shock resistance meeting IEC 60068-2-6 and IEC 60068-2-27
2 years warranty within the conditions of the German Electrical Manufacturer’s Association (ZVEI)
ISO 9001 certified

Important Notes from Hubner Berlin:

The Incremental encoder AHE 7,5 is a opto-electronic precision speed measurement device which must be handled with care by skilled personnel during transportation, mounting and operation.
Hollow shaft must be installed to the motor shaft without pressure to avoid a damage of the ball bearings.
The device is manufactured according to quality standard DIN ISO 9001, EU Declaration of Conformity meeting Council Directive 89/336/EEC art. 10 and annex 1 (EMC Directive).
Do not connect outputs to supply voltage:
!!! Danger of Damage !!!
Please, pay attention to possible voltage drop in long cable leads (input and output).
Shielded cables should be used with twisted lead pairs. If possible, they should be placed uninterrupted and seperately, but at a clear distance from the motor cables. Normally the cable shield is connected to a large surface on the housing via a cable screw or an earth clamp. Cable terminating resistance 120 Ω for TTL and sinewave.
The expected operating life of the devices is governed by the ball bearings, which are manufactured with a permanent lubrication to give approx. 20,000 operating hours (≥ 109 revolutions).
