What Is a Door Sensor?
A door sensor is a sensor that detects the open/close status of a door or panel, and is sometimes called a door switch.
Contact-type sensors include microswitches that have mechanical contacts and judge whether the door is physically pressed or not, and magnet catches with switches that judge whether the door is opened or closed by the flow of electricity. Non-contact type door sensors include photo sensors that determine whether a door is optically shielded, and electromagnetic door sensors that determine whether an electromagnetic force is present.
Uses of Door Sensors
Door sensors are used to confirm the opening and closing of doors in FA equipment systems and other equipment where there is a high risk of injury if a person enters a specific area while the equipment is operating, or in processing machines and other equipment where there is a high risk of injury if a person puts his/her hand in while the equipment is operating.
Also, door sensors are used to check the opening and closing of moving parts such as doors and covers to prevent people from entering safety barriers such as industrial robot systems, etc. Some sensors have a locking mechanism, so that doors cannot be opened until the equipment stops.
Principle of Door Sensors
Door sensors can be used to confirm the opening and closing of doors. Since door sensors are important devices for realizing machine safety, such as preventing worker injury, there are many safety-related standards. For example, there are ISO 14119 and ISO 13849 standards. Door sensors that comply with these standards are called safety door sensors, and systems protected by such door sensors are called interlock systems.
Some door sensors cost several tens of thousands of yen if they include an interlock mechanism, but common microswitches and magnetic catches with switches can be purchased for as little as a few hundred yen.
Even inexpensive door sensors that do not have an interlock mechanism can prevent accidents from occurring if the door is judged to be open in the event of a malfunction, and can perform the minimum function.
Recently, some sensors are equipped with a light-emitting component so that the open/close status of the door can be easily checked by using the color of the sensor itself.
