* Minimizing shaft's moment of inertia (max. 0.5g·cm²)
Specifications* Resolution(P/R) : 100, 200, 320, 360 (not indicated type is available to customize)
* Current consumption : max. 60mA (in case of no load)
* Max. allowable revolution : 6000rpm
* Output signal : A, B, Z phase output (LINE DRIVER output A, -A , B, -B , Z, -Z phase output)
* Control output : NPN O.C output, Voltage output, LINE DRIVER output
* Appearance
- shaft type : External diameter 20mm, height 20mm, shaft diameter 2mm
- hollow shaft built-in type : External diameter 20mm, height 25mm, Inner diameter of shaft 2(2.5, 3)mm
* Power supply : 5VDC±5% , 12VDC±5%

User's Guide
1. Installation
<1> This unit is consisted of precision components. Therefore please treat this productcarefully.
<2> For the installation, please check the assembly dimension of counterpart, then try not to occur the offset between shaft hole and the object. It might shorten the life cycle of the product.
<3> Do not put strong impact when insert coupling into shaft.
<4> Fix the unit or coupling by wrench under 0.15N.m of torque.
2. For using
<1> Please connect shield wire to F.G terminal. (Encoder+Motor+Panel F.G.)
<2> Do not connect and cut circuit off during power on. It may result in damage to thisunit.
<3> When the power source is a Switching Power, please install the surge absorber in power line and wire should be short in order not to be influenced by noise.
<4> Please apply 5VDC to encoder when use Line Driver type.
3. Environment
Please do not use this unit with below environment, it results in malfunction.
<1> Place where this unit or component may be damaged by strong vibration or impact.
<2> Place where there are lots of flammable or corrosive gases.
<3> Place where strong magnet field or electric noise are occurred.
<4> Place where is beyond of rating temperature or humidity.
<5> Place where strong acids or alkali near by.
4. Vibration and Impact
<1> When the strong impact loads on this unit, the error pulse may occur as if the slit isrevolving.
<2> Please fix this unit firmly   when mount it in order to avoid malfunction by residual vibration.
5. Wire connection
<1> Do not pull out the unit after connection with over the rated force(15N).
<2> If use the cable of encoder and high voltage line or power cable in the same conduit,   it may cause a malfunction or mechanical trouble. Please wire separately or use separated conduit.
<3> Please check wire and response frequency when extend wire because of distortion of waveform or residual voltage increment etc by line resistance or capacity betweenlines.
* It may cause malfunction if above instructions are not followed.
