Pull Cord Switch is an emergency switch to stop the belt conveyor instantly when an accident happens. Since the Pull Cord Switch is so designed that it should be installed at the side of belt conveyor and the pull cord should be mounted along conveyor, the switch can be actuated at any position. Stainless steel casing, Weatherproof type: IP67. The internal contact is the Omron micro switch from Japan, with high contact capacity. It can directly control high capacity contactor, with one normally open and one normally closed output. Addition, we also produce pull cord switch which the internal contact is close to the sensor . The contact volume is relatively small, and the maximum load current is 500mA. The current aircraft is used only in special circumstances. Operating principle: When an accident occurs in the transmission Airport , it can affect the cover steel wirecord anywhere along the line in the turn arm, forcing the cam rotating in the machine and driving the micro switch (or the sensor) to work, so that to shut down and prevent accidents expansion by issuing a stop signal. About type A-T1 of pullcord switch with a manual installation, it can reset by pressing the manual installation after troubleshooting. While type A-T2 of pull rope switch can reset automatically. LXB series two-way stainless steelpull cordswitch: Distinguished from the installation form and the shape ,there are six types with the same operating principle: A, B, C, D, E, F. A type for example, focus on the promotion, the protection level is slightly higher than the other types to IP67. The user can choose the situation on the corresponding. The use of the environment and the installation: This machine is suitable for ambient temperature -25 °C +55 °C, relative humidity less than 85% to maintain a normal work environment. In acid, alkali, salt of the regional work, the user should make a text description to our plant for further processing. Switch should be installed in the fixed bracket of the belt rack to keep balance. Tie the cover steel wire rope at both the ends of the pull ring, with each side of the wire preferably not more than 25m. The distance between two cord switches should be reduced slightly when there is a slant.the pullcord forceshould be appropriate to ensure reliable reset switch. It is proposed one ring every 10 meters. According to the required specifications of the users, our factory can provide the cover steel wire rope of good and reliable quality.
