Series MIS is a one-finger type escapement. The MIS has independent fingers for free setting of timing and mounting position to accommodate the work pieces moving down a line. Supply ports on both sides allow selection of piping direction. Separation of the piston and fingers allows easy replacement of fingers for maintenance. Three different finger variations make it possible to freely

Series MIW is a slider guide cylinder, with two sequentially operating fingers. The sequential operation uses a mechanically interlocking cam mechanism in addition to control of air passage to the pistons for reliable separation of work pieces. Separation of the piston and fingers allows easy replacement of fingers for maintenance. Three different finger variations make it possible to
