01 Special Instructions
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.
02 Use conditions required
NO.
