 
		ASRT密封轉(zhuǎn)臺可在灰塵或液體存在的惡劣環(huán)境中提供精確的角度定位。該轉(zhuǎn)臺可以在有灰塵或流體射流的環(huán)境中運行。該ASRT也可以在存在切削液的地方使用。應用范圍從工業(yè)加工自動化到在惡劣環(huán)境中的高精度傳感器定位。該ASRT轉(zhuǎn)臺有效用于產(chǎn)品環(huán)境試驗和一系列跟蹤應用,提供精確的旋轉(zhuǎn)運動。
	
ASRT系列轉(zhuǎn)臺現(xiàn)有三種不同的尺寸,可匹配各種負載和電機額定扭矩。所有尺寸的軸孔選項允許電動,氣動和流體饋通。提供高精度光學(增量或絕對)非接觸式編碼器或堅固的磁性非接觸式編碼器,上述ASRT轉(zhuǎn)臺有許多反饋選項,以滿足對于許多苛刻應用的具體要求。
	
ASRT標準工作溫度為0至70℃。冰點以下工作需要選配空氣吹掃和干燥劑。空氣吹掃平臺可以在-20℃至70℃溫度范圍內(nèi)工作。
	
外殼和硬涂層臺面上的基于聚合物的涂料提供標準的腐蝕防護。該平臺可選棕褐色,黑色和白色涂料顏色。
	
可以提供100至200rpm的轉(zhuǎn)速。該ASRT包括電氣接地軸和外殼,以防止電擊和消除RF再輻射,并且包括外殼接地點。標準的圓形密封連接器,而選項包括干燥劑筒,空氣吹掃選項和安裝法蘭配件。
