Safety switches, also called safety switches, are installed at locations where safety must be ensured, such as machine tool doors and safety fences. A door opening while the machine tool is in motion could lead to serious injury. Therefore, safety switches are necessary to distinguish between machine operation and machine standstill and to ensure that the door opens only when the machine is stopped. There are two types of safety switches: a locking type with a locking mechanism and a non-contact type.
Safety switches are mainly used as interlocking devices that do not allow the operation or startup of equipment in an unsecured state. Furthermore, if you want to lock a door or safety fence so that it will not open while the equipment is in operation, select one with a locking function.
Examples of common uses include the following.
In addition, the safety switch may also be used to ensure the safety of the equipment itself rather than simply for human safety applications. Especially in production lines where multiple robot arms operate in tandem, there is a possibility that the robot arms will come into contact with each other and be damaged if they start operating at an unexpected time. Therefore, it is necessary to configure the equipment to ensure safe operation with the same configuration as above.
There are two main types of safety switches: those with a locking function and those with a non-contact function. The mechanism and features of each are described below.
Generally, the internal structure has a locking mechanism based on the relationship between a "cam" and a "rod ."By moving the "cam" and the "rod," the locking state will switch in response to the opening or closing of the door. The two main locking methods are as follows.
Non-contact type safety switches are used in locations where you must prevent dust and debris. With the locking type, there is a possibility of generating dust and other debris due to wear, but with the non-contact type, there is no need to worry about this. The primary detection methods include magnetic detection and electromagnetic induction. Because of these features, they are suitable for use in clean rooms and food production lines.
