| 行程开关就是用以限定机械设备的运动极限位置的电气开关。这种开关有接触式的和非接触式的。 接触式的比较直观，机械设备的运动部件上，安装上限位开关，与其相对运动的固定点上安装极限位置的挡块，或者是相反安装位置。当限位开关的机械触头碰上挡块时，切断了(或改变了)控制电路，机械就停止运行或改变运行。由于机械的惯性运动，这种行程开关有一定的“超行程”以保护开关不受损坏。限位开关分工作限位开关和极限限位开关，工作限位开关是用来给出机构动作到位信号的。极限限位开关是防止机构动作超出设计范围而发生事故的。工作限位开关安装在机构需要改变工况的位置，开关动作后，给出信号，进行别的相关动作。极限限位开关安装在机构动作的*远端，用来保护机构动作过大出现机构损坏产品范围有:安全门开关和门锁开关、安全传感器、紧急停止拉线开关、安全监Z/T335系列限位开关、行程开关ZS335-11Z,ZR335-11Z,ZS335-02Z,ZR335-02Z,TS335-11Z,TR335-11Z,TS335-11ZU,TR335-11ZU,TS335-20Z,TR335-20Z,TS335-11Zh,TR335-11Zh,TS335-02Z,TR335-02Z,TS335-02Zh,TR335-02Zh,Z4VH335-11Z,Z4V7H335-11Z,Z4V10H335-11Z,Z4VH335-02Z,Z4V7H335-02Z,Z4V10H335-02Z,T4VH335-11Z,T4V7H335-11Z,T4V10H335-11Z,T4VH335-11ZU,T4V7H335-11ZU,T4V10H335-11ZU,T4VH335-20Z,T4V7H335-20Z,T4V10H335-20Z,T4VH335-20Zh,T4V7H335-20Zh,T4V10H335-20Zh,T4VH335-02Z,T4V7H335-02Z,T4V10H335-02Z,T4VH335-02Zh,T4V7H335-02Zh,T4V10H335-02Zh,TVH335-01/01Z,Z1K335-11Z,Z3K-335-11Z,Z1K335-02Z,Z3K-335-02Z,T1K335-11Z,T3K-335-11Z,T1K335-11ZU,T3K-335-11ZU,T1K335-20Z,T3K-335-20Z,T1K335-20Zh,T3K-335-20Zh,T1K335-02Z,T3K-335-02Z,T1K335-02Zh,T3K-335-02ZhZ/T336系列限位开关ZS336-11Z,ZR336-11Z, ZS336-02Z,ZR336-02Z, TS336-11Z,TR336-11Z, TS336-11ZU,TR336-11ZU,TS336-20Z,TR336-20Z,TS336-11Zh,TR336-11Zh,TS336-02Z,TR336-02Z,TS336-02Zh,TR336-02Zh,Z4VH336-11Z,Z4V7H336-11Z,Z4V10H336-11Z,Z4VH336-02Z,Z4V7H336-02Z,Z4V10H336-02Z,T4VH336-11Z,T4V7H336-11Z,T4V10H336-11Z,T4VH336-11ZU,T4V7H336-11ZU,T4V10H336-11ZU,T4VH336-20Z,T4V7H336-20Z,T4V10H336-20Z,T4VH336-20Zh,T4V7H336-20Zh,T4V10H336-20Zh,T4VH336-02Z,T4V7H336-02Z,T4V10H336-02Z,T4VH336-02Zh,T4V7H336-02Zh,T4V10H336-02Zh,TVH336-01/01Z,Z1K336-11Z,Z3K-336-11Z,Z1K336-02Z,Z3K-336-02Z,T1K336-11Z,T3K-336-11Z,T1K336-11ZU,T3K-336-11ZU,T1K336-20Z,T3K-336-20Z,T1K336-20Zh,T3K-336-20Zh,T1K336-02Z,T3K-336-02Z,T1K336-02Zh,T3K-336-02ZhZS332系列限位开关ZS332-11y,ZR332-11y,Z4VH332-11y,Z4V10H332-11y,Z4V7H332-11ySMS3-100-100, SMS3-100-150,标准限位开关（Z/T235、Z/T 236 、Z/T 256 、Z/T 335 、Z/T 336 、Z332、Z/T 355系列）Z/T235系列限位开关AZ235-11Z,ZR235-11Z,TS235-11Z,TR235-11Z,TS235-20Z,TR235-20Z,TS235-02Z,TR235-02Z,Z4S235-11Z,Z4R235-11Z,ZK235-11Z,T4S235-11Z,T4R235-11Z,TK235-11Z,T4S235-20Z,T4R235-20Z,TK235-20Z,T4S235-02Z,T4R235-02Z,TK235-02Z,ZV12H235-11Z,ZV14H235-11Z, TV12H235-11Z,TV14H235-11Z,TV12H235-20Z,TV14H235-20Z,TV12H235-02Z,TV14H235-02Z,ZV10H235-11Z,Z3K235-11Z, TV10H235-11Z,T3K235-11Z, TV10H235-20Z,T3K235-20Z,TV10H235-02Z,T3K235-02Z,Z4K235-11Z,ZK4235-11Z,T4K235-11Z,TK4235-11Z,T4K235-20Z,TK4235-20Z, T4K235-02Z,TK4235-02ZZ/T236系列限位开关ZS236-11Z,ZR236-11Z,TS236-11Z,TR236-11Z,TS236-20Z,TR236-20Z, TS236-02Z,TR236-02Z,Z4R236-11Z,ZK236-11Z,T4R236-11Z,TK236-11Z,T4R236-20Z,TK236-20Z,T4R236-02Z,ZK236-02Z,ZV1H236-11Z,Z1R236-11Z, TV1H236-11Z,T1R236-11Z, TV1H236-20Z,T1R236-20Z, TV1H236-02Z,T1R236-02Z, ZV10H236-11Z,Z3K236-11Z, TV10H236-11Z,T3K236-11Z, TV10H236-20Z,T3K236-20Z,TV10H236-02Z,T3K236-02Z,Z4K236-11Z,ZK4236-11Z,T4K236-11Z,TK4236-11Z,T4K236-20Z,TK4236-20Z, T4K236-02Z,TK4236-02ZZ/T256系列限位开关ZS256-11Z,ZR256-11Z,TS256-11Z,TR256-11Z,TS256-20Z,TR256-20Z, TS256-02Z,TR256-02Z,Z4S256-11Z,Z4R256-11Z,ZK256-11Z,T4S256-11Z,T4R256-11Z,TK256-11Z,T4S256-20Z,T4R256-20Z,TK256-20Z,T4S256-02Z,T4R256-02Z,TK256-02Z,Z3K256-11Z,Z4K256-11Z,T3K256-11Z,T4K256-11Z,T3K256-20Z,T4K256-20Z,T3K256-02Z,T4K256-02Z,ZK4256-11Z,ZV1H256-11Z,ZV7H256-11Z, TK4256-11Z,TV1H256-11Z,TV7H256-11Z, TK4256-20Z,TV1H256-20Z,TV7H256-20ZTK4256-02Z,TV1H256-02Z,TV7H256-02Z,ZV10H256-11Z, TV10H256-11Z, TV10H256-20Z,TV10H256-02Z,Z/T335系列限位开关、行程开关ZS335-11Z,ZR335-11Z, ZS335-02Z,ZR335-02Z, TS335-11Z,TR335-11Z, TS335-11ZU,TR335-11ZU,TS335-20Z,TR335-20Z,TS335-11Zh,TR335-11Zh,TS335-02Z,TR335-02Z,TS335-02Zh,TR335-02Zh,Z4VH335-11Z,Z4V7H335-11Z,Z4V10H335-11Z,Z4VH335-02Z,Z4V7H335-02Z,Z4V10H335-02Z,T4VH335-11Z,T4V7H335-11Z,T4V10H335-11Z,T4VH335-11ZU,T4V7H335-11ZU,T4V10H335-11ZU,T4VH335-20Z,T4V7H335-20Z,T4V10H335-20Z,T4VH335-20Zh,T4V7H335-20Zh,T4V10H335-20Zh,T4VH335-02Z,T4V7H335-02Z,T4V10H335-02Z,T4VH335-02Zh,T4V7H335-02Zh,T4V10H335-02Zh,TVH335-01/01Z,Z1K335-11Z,Z3K-335-11Z,Z1K335-02Z,Z3K-335-02Z,T1K335-11Z,T3K-335-11Z,T1K335-11ZU,T3K-335-11ZU,T1K335-20Z,T3K-335-20Z,T1K335-20Zh,T3K-335-20Zh,T1K335-02Z,T3K-335-02Z,T1K335-02Zh,T3K-335-02Zh |
