D4BS-15FS

The D4BS series Safety-door Switch special operation key positively pulls apart the contacts from each other and contributes to the safety of the production site. The exclusive-use operation key is provided to assure accurate switching operation. A triangular set zone mark makes it easy to adjust the operating position when inserting the operation key. The switch head is coated with easy-to-see red paint. The mounting direction of the switch head can be varied to any of the four directions. A shearing force contact separating mechanism (NC contact) is employed, which positively pulls apart the contacts from each other by using shearing force if any abnormality such as contact welding should occur in the contact area. There is a difference in level between the NC and NO terminal, which assures easy wiring. The operation plunger employs an oil seal, with which the switch box meets the requirements of IP67 (the sealing capability of the operation key's insertion mouth is IP00).
