(1) corrosive gasses atmosphere (ex. chlorine gas, hydrogen sul? de gas, ammonia gas, sulfuric acid gas, nitric oxide gas, etc.) (2) in liquid (ex. water, oil, medical liquid, organic solvent, etc.) (3) dusty / dirty atmosphere (4) direct sunlight (5) static voltage nor electric/magnetic ? elds (6) direct sea breeze (7) other variations of the above c notice (soldering and mounting) continued on the following page. r51e.pdf mar.1,2013 9 ! note ? please read rating and ! caution (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc. ? this catalog has only typical speci? cations. therefore, please approve our product speci? cations or transact the approval sheet for product speci? cations before ordering. 1. soldering (1) sv01 series can be soldered by re? ow soldering method and soldering iron. do not use ? ow soldering method (dipping). (2) the dimension of land pattern used should be murata's standard land pattern at re? ow soldering. excessive land area may cause displacement due to the effect of the surface tension of the solder. insuf? cient land area may cause insuf? cient soldering strength on pcb (smd type). (3) soldering conditions refer to the temperature pro? le. if the soldering conditions are not suitable, e.g., excessive time and/or excessive temperature, the rotary position sensor may deviate from the speci? ed characteristics. (4) the amount of solder is critical. insuf? cient amounts of solder can lead to insuf? cient soldering strength on pcb. excessive amounts of solder may cause bridging between the terminals. (5) the soldering iron should not come in contact with the cover of the rotary position sensor. if such contact does occur, the rotary position sensor may be damaged. 2. mounting (1) use pcb hole to meet the pin of the rotary position sensor. if the rotary position sensor is inserted into insuf? cient pcb hole, the rotary position sensor may be damaged by mechanical stress (lead type). (2) do not apply excessive force, preferable 9.8n max. (ref. 1kgf) when the rotary position sensor is mounted to the pcb. (3) do not warp and/or bend pcb to prevent the rotary position sensor from breakage. 3. cleaning cannot be cleaned because of open construction.

(1) data install should be done plural times and applied the mean value. (2) data considered as error should be invalid. (3) if suspicious data is found, the data should be re-installed. 3. before using rotary position sensor, please test after assembly in your particular mass production system. 4. murata cannot guarantee rotary position sensor integrity when used under conditions other than those speci ed in this document.

(-angle can be fixed by one hole or two holes.) (2) positioning accuracy compared to an smd product, there is a tendency for large variations in the mounting position of the product to occur. if positioning accuracy is important when making connection to a mechanical part, we recommend that you use an smd product. determine the dimension of the locating holes as follows, depending upon the method of mounting the product (when mounting the product using a mounter or mounting it by hand). q when mounting the product by hand w when using a mounter expand the size of each hole to account for the accuracy of the mountes. note, however, that the accuracy of the mounting position of the product is determined by the "accuracy of the mounter". <2> leaded parts (1) thru-holes determine the thru-hole positions so as to match the terminal pitch of the product. if you attempt to mount the product into thru-holes that do not match the terminal pitch, the terminals may become deformed and in the worst case may break. also, random variations in the mounting position of the product may occur. in order to prevent the above trouble, use our standard thru-hole dimensions. continued on the following page. continued from the preceding page. 5.5 8.2 14.9 4-0.80.1 8.50.1 5.0 ( tolerance: 0.3 in mm ) locating pins boss ( tolerance: 0.1 in mm ) 751 r6.95 1.100.05 2.0 ?5.100.05 ?2.0 standard thru-hole dimensions ( tolerance: 0.1 in mm ) ?2.0 5.00.1 sv03 sv01 7.0 5.5 ?5.100.05 4-?1.0 +0.1 C0 751 r6.95 2.0 1.100.05 5.0 7.0 5.5 4-?1.0 +0.1 C0

(in the case of a shaft that is integral with the gear, apply lubricant only to the gear teeth.) 1. do not apply a load other than rotational motion to the bearing. 2. do not allow grease or other lubricant to get into the product. continued on the following page. continued from the preceding page. this product has increased contact resistance (sliding noise) in order to maximize its rotational life. consequently, in order to reduce the effect of sliding noise, it is necessary to reduce the current flowing through the contacts (current i indicated in the figure at right) as far as possible. accordingly, take steps to ensure that the internal impedance of the circuit connected to the output terminal (#2 terminal) is at least 1m. be particularly careful in the case of the filter circuit shown in the figure at right. 3. ensure that the connection impedance is at least 1m. do not rheostat connect as shown in the figure at right due to the contact resistance is slightly high. #3 terminal #2 terminal #1 terminal slider resistive element resin substrate rotor #2 terminal cover bearing product do not apply grease to shaft. apply lubricant only to gear teeth. a/d product i
