【XTD-SJ系列拉繩開關 產品介紹（中文版）】
XTD-SJ系列拉繩開關是一款專為工業(yè)設備安全防護設計的機械式觸發(fā)裝置，適用于各類輸送機械、礦山設備、起重機械及自動化生產線的緊急停機控制。本產品采用模塊化結構設計，通過柔性拉繩與設備聯(lián)動，可在突發(fā)狀況下實現(xiàn)快速響應，有效保障操作人員與設備安全。
產品核心部件選用工程尼龍與金屬復合材料制造，主體外殼通過注塑工藝一體成型，具備良好的抗沖擊性和耐腐蝕性。傳動機構采用銅合金精密加工而成，配合不銹鋼彈簧系統(tǒng)，確保動作靈敏度長期穩(wěn)定。拉繩支架支持多角度調節(jié)安裝，適配直徑4-8mm的鋼絲繩或尼龍繩，最大拉伸行程可達20米。雙觸點設計增強了信號傳輸可靠性，觸點壽命達10萬次以上，適合高頻次作業(yè)環(huán)境。
在極端工況環(huán)境下表現(xiàn)優(yōu)異，工作溫度范圍覆蓋-30℃至+80℃，防護等級滿足常規(guī)粉塵、油污及輕度噴濺防護要求。獨特的三防處理工藝使產品在潮濕、高溫等復雜場景中仍保持穩(wěn)定性能。安裝過程無需專業(yè)工具，可根據(jù)現(xiàn)場需求選擇壁掛式或支架式固定方案，標配的防松脫緊固件有效預防長期振動導致的部件移位。
本系列產品已成功應用于水泥生產線急停系統(tǒng)、港口輸送機安全防護、食品加工設備聯(lián)動控制等多個領域。產品提供銀觸點與金觸點兩種版本選擇，分別對應常規(guī)工況與高精度信號傳輸需求。售后服務體系覆蓋全國主要工業(yè)城市，提供12個月質保期及專業(yè)技術支持。
【XTD-SJ Series Pull Cord Switch Product Introduction（English Version）】
The XTD-SJ series pull cord switch is a mechanical triggering device specifically designed for industrial equipment safety protection, suitable for emergency stop control in various conveying machinery, mining equipment, lifting systems, and automated production lines. Featuring a modular structure, this product connects with equipment through flexible cables to enable rapid response during emergencies, effectively ensuring personnel and equipment safety.
Constructed with engineering nylon and metal composite materials, the main housing adopts injection molding technology for superior impact resistance and corrosion protection. The transmission mechanism employs precision-machined brass components combined with stainless steel spring systems, maintaining long-term operational sensitivity. The adjustable rope bracket supports multi-angle installation, compatible with 4-8mm steel wire or nylon cables, offering maximum tensile travel up to 20 meters. Dual-contact design enhances signal transmission reliability, with contact endurance exceeding 100,000 cycles, ideal for high-frequency operation environments.
Demonstrating exceptional performance under extreme conditions, the switch operates reliably within -30℃ to +80℃ temperature range, providing standard protection against dust, oil contamination, and light liquid splashes. Specialized surface treatment ensures consistent functionality in humid or high-temperature environments. Tool-free installation allows flexible wall-mounted or bracket-fixed configurations, with anti-loosening fasteners preventing component displacement caused by prolonged vibration.
This product series has been successfully implemented in cement production line emergency systems, port conveyor safety protection, and food processing equipment interlock controls. Available in silver-contact and gold-contact versions to meet general and high-precision signal transmission requirements respectively. Comprehensive after-sales services cover major industrial cities nationwide, including 12-month warranty and professional technical support.
