Welcome you visit my website (www,dernfu.cn/gb/products.asp?Categoryid=65 ) ,you will find some products in my website,which I had made for my customers before. More than 60 % of my solenoids had been maken according to customer's specification. If you can't find the product in my website which you want,please do not hesitate to contact me (email: david-dernfu.com,86-0-13825752157)concerning any solenoid specific questions.
Any inquiry please provide product usage, engineering drawing (I should know its dimension range (mm),working voltage(V), stoke(mm), force(gr), working cycle(%), some solenoids should provide its power(Watt)) or samples, purchasing schedule (samples quantity, quantity per order, total quantity in one year,etc), target price (the target price base on Ex works, we can agree different delivery term).
