L18
The sealed linear encoder L18 is used to convert linear displacements of key machine components into electrical signals containing information about the value and direction of the displacement.
The encoder consists of a glass scale installed into a rigid hollow housing and a ball-bearing-guided reading head. To be able to work in harsh environments (lubricants and chips), the encoder has sealing lips.
Filtered air can be supplied into the housing of the encoder for extra protection.
The photoelectric unit of the reading head generates sinusoidal micro-current or TTL square-wave (standard RS422) output signals.
Three versions of output signals are available:
• L18-A - Sinusoidal signals, with amplitude approx. 11 μApp, require external subdividing electronics.
• L18-AV - Sinusoidal signals, with amplitude approx. 1 Vpp, require external subdividing electronics.
• L18-F - Square-wave, with integrated subdividing electronics for interpolation x1, x2, x5, x10, x 25, x50.

L37
The precision sealed linear encoder L37 is used to convert linear displacements of key machine components into electrical signals containing information about the value and direction of the displacements.
The encoder consists of a glass scale installed into a rigid hollow housing and a ball-bearing-guided reading head. To be able to work in harsh environments (cooling liquid, lubricants and chips), the encoder has two rows of sealing lips. Filtered air can be supplied into the housing of the encoder for extra protection from dust. The photoelectric unit of the reading head generates sinusoidal micro-current or square-wave output signals.
Characteristic feature of encoder is a rigid housing that provides better resistance to vibration and higher protection grade due to two pairs of sealing lips.
L37 is fixed to the mounting surface at the midpoint. Reproducible thermal behavior is permitted by flexible fastening elements.
Reference mark can be selected by magnet, which moves in horizontal groove on the front side of encoder (optional).
Three versions of output signals are available:
- L37-А - sinusoidal signals, with amplitude approx. 11 μApp, require an external subdividing electronics.
- L37-АV- sinusoidal signals, with amplitude approx. 1 Vpp, require an external subdividing electronics.
- L37-F - square-wave signals, type TTL or HTL (standard RS422) with integrated subdividing electronics for interpolation x1, x2, x5, x10, x25, x50.

二、實物圖、安裝方法及使用注意事項：
1、precizika立陶宛光柵尺實物圖：
2、precizika立陶宛光柵尺安裝指導(dǎo)
光柵尺線位移傳感器的安裝比較靈活，可安裝在機(jī)床的不同部位。
*般將主尺安裝在機(jī)床的工作臺（滑板）上，隨機(jī)床走刀而動，讀數(shù)頭固定在床身上，盡可能使讀數(shù)頭安裝在主尺的下方。其安裝方式的選擇必須注意切屑、切削液及油液的濺落方向。如果由于安裝位置限制必須采用讀數(shù)頭朝上的方式安裝時，則必須增加輔助密封裝置。另外，*般情況下，讀數(shù)頭應(yīng)盡量安裝在相對機(jī)床靜止部件上，此時輸出導(dǎo)線不移動易固定，而尺身則應(yīng)安裝在相對機(jī)床運(yùn)動的部件上（如滑板）。
光柵尺線位移傳感器安裝基面
安裝光柵尺傳感器時，不能直接將傳感器安裝在粗糙不平的機(jī)床身上，更不能安裝在打底涂漆的機(jī)床身上。光柵主尺及讀數(shù)頭分別安裝在機(jī)床相對運(yùn)動的兩個部件上。用千分表檢查機(jī)床工作臺的主尺安裝面與導(dǎo)軌運(yùn)動的方向平行度。千分表固定在床身上，移動工作臺，要求達(dá)到平行度為0.1mm/1000mm以內(nèi)。如果不能達(dá)到這個要求，則需設(shè)計加工*件光柵尺基座。
基座要求做到：(1)應(yīng)加*根與光柵尺尺身長度相等的基座（基座長出光柵尺50mm左右）。(2)該基座通過銑、磨工序加工，其平面平行度0.1mm/1000mm以內(nèi)。另外，還需加工*件與尺身基座等*的讀數(shù)頭基座。讀數(shù)頭的基座與尺身的基座總共誤差不得大于±0.2mm。安裝時，調(diào)整讀數(shù)頭位置，達(dá)到讀數(shù)頭與光柵尺尺身的平行度為0.1mm左右，讀數(shù)頭與光柵尺尺身之間的間距為1~1.5mm左右。
光柵尺線位移傳感器主尺安裝
將光柵主尺用M4螺釘上在機(jī)床安裝的工作臺安裝面上，但不要上緊，把千分表固定在床身上，移動工作臺（主尺與工作臺同時移動）。用千分表測量主尺平面與機(jī)床導(dǎo)軌運(yùn)動方向的平行度，調(diào)整主尺M(jìn)4螺釘位置，使主尺平行度滿足0.1mm/1000mm以內(nèi)時，把M2螺釘上緊。
在安裝光柵主尺時，應(yīng)注意如下三點：
(1) 在裝主尺時，如安裝超過1.5M以上的光柵時，不能象橋梁式只安裝兩端頭，尚需在整個主尺尺身中有支撐。(2)在有基座情況下安裝好后，用*個卡子卡住尺身中點（或幾點）。(3)不能安裝卡子時，用玻璃膠粘住光柵尺身，使基尺與主尺固定好。
光柵尺線位移傳感器讀數(shù)頭的安裝
在安裝讀數(shù)頭時，*先應(yīng)讀數(shù)頭的基面達(dá)到安裝要求，然后再安裝讀數(shù)頭，其安裝方法與主尺相似。后調(diào)整讀數(shù)頭，使讀數(shù)頭與光柵主尺平行度在0.1mm之內(nèi)，其讀數(shù)頭與主尺的間隙控制在1~1.5mm以內(nèi)。
光柵尺線位移傳感器限位裝置
光柵線位移傳感器全部安裝完以后，*定要在機(jī)床導(dǎo)軌上安裝限位裝置，以免機(jī)床加工產(chǎn)品移動時讀數(shù)頭沖撞到主尺兩端，從而損壞光柵尺。另外，用戶在選購光柵線位移傳感器時，應(yīng)盡量選用超出機(jī)床加工尺寸100mm左右的光柵尺，以留有余量。
光柵尺線位移傳感器檢查
光柵線位移傳感器安裝完畢后，可接通數(shù)顯表，移動工作臺，觀察數(shù)顯表計數(shù)是否正常。
在機(jī)床上選取*個參考位置，來回移動工作點至該選取的位置。數(shù)顯表讀數(shù)應(yīng)相同（或回零）。另外也可使用千分表（或百分表），使千分表與數(shù)顯表同時調(diào)至零（或記憶起始數(shù)據(jù)），往返多次后回到初始位置，觀察數(shù)顯表與千分表的數(shù)據(jù)是否*。
通過以上工作，光柵尺線位移傳感器的安裝就完成了。但對于*般的機(jī)床加工環(huán)境來講，鐵屑、切削液及油污較多。因此，傳感器應(yīng)附帶加裝護(hù)罩，護(hù)罩的設(shè)計是按照傳感器的外形截面放大留*定的空間尺寸確定，護(hù)罩通常采用橡皮密封，使其具備*定的防水防油能力。
3、precizika立陶宛光柵尺使用注意事項
（1）光柵尺傳感器與數(shù)顯表插頭座插拔時應(yīng)關(guān)閉電源后進(jìn)行。
（2）盡可能外加保護(hù)罩，并及時清理濺落在尺上的切屑和油液，嚴(yán)格防止任何異物進(jìn)入光柵尺傳感器殼體內(nèi)部。
（3）定期檢查各安裝聯(lián)接螺釘是否松動。
（4）為延長防塵密封條的壽命，可在密封條上均勻涂上*薄層硅油，注意勿濺落在玻璃光柵刻劃面上。
（5） 為光柵尺傳感器使用的可靠性，可每隔*定時間用酒*清洗擦拭光柵尺面及指示光柵面，保持玻璃光柵尺面清潔。
（6） 光柵尺傳感器嚴(yán)禁劇烈震動及摔打，以免破壞光柵尺，如光柵尺斷裂，光柵尺傳感器即失效了。
（7） 不要自行拆開光柵尺傳感器，更不能任意改動主柵尺與副柵尺的相對間距，否則*方面可能破壞光柵尺傳感器的*度；另*方面還可能造成主柵尺與副柵尺的相對摩擦，損壞鉻層也就損壞了柵線，以而造成光柵尺報廢。
（8） 應(yīng)注意防止油污及水污染光柵尺面，以免破壞光柵尺線條紋分布，引起測量誤差。
（9） 光柵尺傳感器應(yīng)盡量避免在有嚴(yán)重腐蝕作用的環(huán)境中工作，以免腐蝕光柵鉻層及光柵尺表面，破壞光柵尺質(zhì)量。
