2 Option Cable connector It is recommendable to use a cable connector when the cable path is long, or a separation of cable path is necessitated. We employ Sumitomo 3M s sensor connector, namely Mini-Clamp Connector, and have the loose wires coated with hot-melt resin. The connector has high reliability and prevents connect failure when jointing/releasing. Connector jointed Cable connector joint state Hot-melt protection Connector released for safety use Correct wiring Mounting the switch Although our products are designed to ensure safety and address risks, in case that a switch malfunction or failure is expected to lead to serious risks to life or property, please be advised to expand further safety gear such as the incorporation of dual circuit. 1Prevention of reverse connectionplease observe the circuit diagrams so as to ensure correct connections. Reverse connection of power supply is strictly prohibited. 2Relay drivewhen driving a relay, please connect a freewheel diode in parallel. 1Clamping torqueplease observe the value of torque designated for each switch. 2Cable handlingdo not subject the connecting part between cable and switch-head to tensiontensile strength as 20N at max., the bending radius as 7mm at least Examples for Application of Screw-type Switches Touch Sensor, Sensor for bottom dead center Example of mounting in stop wall Example of using stop nut Example of using stop block Sensing position Stopper Stopper Stopper 16
