S4A Industrial Co., Limited, Founded in 2010, We have been dedicating in access control production R&D and sales for 12 year.
S4A mainly produces a series of security Door Access Control such as:Network Access Controller, Locker board, Electromagnetic lock, Standalone door Controller, Automatic door opener, etc. Electromagnetic lock has various styles, including holding force 60kg, 180kg, 280kg, 350kg, 500kg,1200kg magnetic lock. Single door and double door EM lock. Functions are with led, with feedback, with timer. With anti-residual magnetism designed and complete mouning brackets, magnetic locks are widely used for glass door, wooden door, fireproof door, sliding door and metal door.
