核心優(yōu)勢(shì)
-
可靠觸發(fā)機(jī)制
采用雙向觸發(fā)設(shè)計(jì)，支持水平或垂直方向拉繩操作，確保緊急情況下任意角度均可快速響應(yīng)。內(nèi)部精密彈簧結(jié)構(gòu)配合耐磨觸點(diǎn)組件，實(shí)現(xiàn)超過50萬次的標(biāo)準(zhǔn)動(dòng)作壽命。
-
環(huán)境適應(yīng)性
殼體采用高強(qiáng)度鋁合金壓鑄成型，表面經(jīng)陽極氧化處理，防護(hù)等級(jí)達(dá)到IP67，可在-30℃至+80℃溫度范圍及粉塵、潮濕等嚴(yán)苛工況下穩(wěn)定運(yùn)行。嵌入式密封設(shè)計(jì)有效防止內(nèi)部元件受潮腐蝕。
-
靈活安裝配置
提供壁掛式與支架式兩種固定方案，支持單側(cè)或雙側(cè)拉繩接入。標(biāo)配3米高強(qiáng)度尼龍牽引繩（可定制長(zhǎng)度），繩體內(nèi)置防斷裂預(yù)警纖維層，便于日常狀態(tài)巡檢。
