SN2170-SL-C Automatic Reset Rope Switch SN2170-SL-C Automatic Reset Rope Switch SN2170-SL-C Automatic Reset Rope Switch Scope of Application Rope Switch is a switch type sensor (i.e. contactless travel switch) mainly used for emergency parking of conventional belt conveyors, shuttle conveyors, skirt type feeding conveyors, bucket elevators, packaging production lines, stacking/reclaiming systems, cranes, excavators, ship loading and unloading systems, horizontal feeders, and other equipment on site. When an emergency occurs, pulling the rope switch at any location along the site can issue a shutdown signal, achieving protection for personnel and equipment. Because it has the characteristics of both a travel switch and a micro switch, as well as sensing performance, and is reliable in action, stable in performance, fast in frequency response, long in service life, strong in resistance to interference, waterproof, shockproof, and corrosion-resistant. Widely used in industries such as machinery, mining, textiles, printing, chemical engineering, metallurgy, light industry, valves, power, security, railways, transportation, cement, ports, etc. Pull cord switches may be used in some enterprises, but they may not be seen in many places. In fact, some rural areas still use pull cord switches. Although the people have become wealthy, some rural areas still use drawstring switches. Manual reset pull cord switch (pull cord switch) - With a mechanical locking device at the triggering position, the emergency stop command can remain locked and can be manually reset at the head of the switch. Main function: Positive action: The switch has a positive disconnect operation contact, and the switch is triggered by a positive action. Lock: The switch is locked in the triggered position (NC safety contact opens), and the NO contact is only used to send signals. Reset: The switch comes with a reset button to reclose the safety contacts. The machine can only be restarted by manually operating the control equipment in the starting circuit that is far from the pull switch< H, E12-20D0.1PK, E12-20D0.1PH, E12-20T3NK, E12-20T3NH, E12-20T3PK, E12-20T3PH, E18-20D0.1NK, E18-20D0.1NH, E18-20D0.1NT, E18-20D0.1PK, E18-20D0.1PH, E18-20D0.1PT, E18-20D0.1DK, E18-20D0.1DH, E18-34D0.1GK, E18-34D0.1GH, E18-20R3NK, E18-20R3NH, E18-20R3NT E18-20R3PK, E18-20R3PH, E18-20R3PT, E18-20R3DK, E18-20R3DH, E18-34R3GK, E18-34R3GH, E18-20T10NK, E18-20T10NH, E18-20T10NT, E18-20T10PK, E18-20T10PH, E18-20T10PT, E18-20T10DK, E18-20T10DH, E18-34T10GK, E18-34T10GH, E30 series: E30-20D1NK E30-20D1NH、E30-20D1NT、E30-20D1PK、E30-20D1PH、E30-20D1PT、E30-20D1DK、E30-20D1DH、E30-34D1GK、E30-34D1GH、E30-20R4NK、E30-20R4NH、E30-20R4NT、E30-20R4PK、E30-20R4PH、E30-20R4PT、E30-20R4DK、E30-20R4DH、E30-34R4GK、E30-34R4GH、E30-20T20NK、E30-20T20NH、E30-20T20NT、E30-20T20PK、E30-20T20PH、E30-20T20PT、E30-20T20DK、E30-20T20DH、E30-34T20GK、E30-34T20GH、E41-20D0.5NK、E41-20D0.5NH、E41-20D0.5NT、E41-20D0.5PK、E41-20D0.5PH、E41-20D0.5PT、E41-20D0.5DK、E41-20D0.5DH、E41-20R2NK、E41-20R2NH、E41-20R2NT、E41-20R2PK、E41-20R2PH、E41-20R2PT、E41-20R2DK、E41-20R2DH、E41-20T5NK、E41-20T5NH、E41-20T5NT、E41-20T5PK、E41-20T5PH、E41-20T5PT、E41-20T5DK、E41-20T5DH、E47-20D0.3NK、E47-20D0.3NH、 E47-20D0.3NT、E47-20D0.3PK、E47-20D0.3PH、E47-20D0.3PT、E47-20D0.3DK、E47-20D0.3DH、E47-20R2NK、E47-20R2NH、E47-20R2NT、E47-20R2PK、E47-20R2PH、E47-20R2PT、E47-20R2DK、E47-20R2DH、E47-20T5NK、E47-20T5NH、E47-20T5NT、E47-20T5PK、E47-20T5PH、E47-20T5PT、E47-20T5DK、E47-20T5DH、E50-20D0.3NK、E50-20D0.3NH、E50-20D0.3NT、E50-20D0.3PK、E50-20D0.3PH、E50-20D0.3PT、E50-20D0.3DK、E50-20D0.3DH、E50-34D0.3GK、E50-34D0.3GH、E50-34D0.3GJ、E50-20R2NK、E50-20R2NH、E50-20R2NT、E50-20R2PK、E50-20R2PH、E50-20R2PT、E50-20R2DK、E50-20R2DH、E50-34R2GK、E50-34R2GH、E50-34R2GJ、E50-20T5NK、E50-20T5NH、E50-20T5NT、E50-20T5PK、E50-20T5PH、E50-20T5PT、E50-20T5DK、E50-20T5DH、E50-34 T5GK、E50-34T5GH、E50-34T5GJ、 E52-20D0.3NK、E52-20D0.3NH、E52-20D0.3NT、E52-20D0.3PK、E52-20D0.3PH、E52-20D0.3PT、E52-20D0.3DK、E52-20D0.3DH、E52-20R2NK、E52-20R2NH、E52-20R2NT、E52-20R2PK、E52-20R2PH、E52-20R2PT、E52-20R2DK、E52-20R2DH、E52-20T5NK、E52-20T5NH、E52-20T5NT、E52-20T5PK、E52-20T5PH、E52-20T5PT、E52-20T5DK、E52-20T5DH、E57-20D0.3NK、E57-20D0.3NH、E57-20D0.3NT、E57-20D0.3PK、E57-20D0.3PH、E57-20D0.3PT、E57-20D0.3DK、E57-20D0.3DH、E57-20R1NK、E57-20R1NH、E57-20R1NT、E57-20R1PK、E57-20R1PH、E57-20R1PT、E57-20R1DK、E57-20R1DH、E57-20T5NK、E57-20T5NH、E57-20T5NT、E57-20T5PK、E57-20T5PH、E57-20T5PT、E57-20T5DK、E57-20T5DH、E60-20D0.5NK、E60-20D0.5NH、E60-20D0.5NT、E60-20D0.5PK、E60-20D0.5PH、E60-20D0.5PT、 E60-20D0.5DK, E60-20D0.5DH, E60-20R2NK, E60-20R2NH, E60-20R2NT, E60-20R2PK, E60-20R2PH, E60-20R2PT, E60-20R2DK, E60-20R2DH, E60-20T5NK, E60-20T5NH, E60-20T5NT, E60-20T5PK, E60-20T5PH, E60-20T5PT, E60-20T5DK, E60-20T5DH,
