02 特殊說明 Special Instructions
產品線圈采取正、負脈沖激勵（1、2 端），激勵時間 200ms≤t≤1s，線圈 不能持續長期通電，操作頻率不得超過每分鐘 6 次，并且脈沖應是方波，正脈 沖使觸點閉合，負脈沖使觸點斷開，線圈去激勵后，接觸器觸點狀態由產品內 的永久磁鐵保持。
Product coil is excited by positive and negative pulse(1,2points), 200ms≤t≤ 1s,Long time continuous energizing is not allowed, Operation frequency no more than 6time/min,lt`s square pulse and positive pulse makes the contact close while negative pulse makes the contact open,After the excitation,the permanent magnet in product keeps the state of the contact。
