Two way pull rope switch is commonly known as "emergency stop switch". When it is required to stop at the belt conveyor site, the conveyor is stopped by the switching action. Introduction Two-way pull rope switch is a kind of protection device, which is used to close the running machine as meeting the emergency. When there is any accident in present, the user can start the Two-way Switch anywhere and output the shutdown signals. Technical info Contact Capacity: AC380C 2A Insulation voltage: AC1000V, testing one minute Service Life: 10,000 times Output contact: A group normally opens, the other group normally closed. One group converts switch contact; Ambient temperature: -40 ℃ to +60 ℃ Relative temperature: not more than 90% Atmospheric pressure: 80 ~ 110 Kpa Altitude: < 2,000 M Protection Level: IP65 Action angle: 15° Limit angle 75° Product range ModelContact capacityContact quantityAction powerRestoration typeAction tripLimit tripProtection LevelWeight Normal Open Normal closed LSKG-I≤380V ≤3A1112±2 kgAutomatic Restoration15±2mm20±2mmIP651.2 kg LSKG-II22Manual RestorationIP651.25 kg Working principle As occurring emergency of belt conveyor machine, pull steel cord of pull cord switches to realize emergency stop or give alarm signal. There are two model of pull cord switch, one is automatic restoration, the other one is manual restoration. Structure features 1. Aluminum alloy shell reaches high strength, lightweight, shell of pull cord switch can reach IP 67, it can be worked under extremes environment for long time. 2. Large capacity of electric shock, moves sensitive and reliable. Usage and installations Install pull cord switches every 30 meters on frames of conveyor machines, linked by steel cord through ring-pull of pull cord switches, adjust proper steel cord pressure to ensure restoration of pull cord switches. Connection cables Two way pull rope switches are equipped three-core cable, and mark No.1, No.2 and No.3 cables. No.1 and No.2 are normal open contact, No.1 and No.3 are normal close contact, if two normal open and two normal close, please advise it before ordering.Pull Cord Switch website:http://www.arphu-en.com/conveyor-auxiliary-devices/pull-cord-switch/
