A door switch includes a casing, a cam, the cam being caused to operate by manipulation of a manipulation key, and a detection unit for detecting an operating state of the cam. The casing houses at least a part of the cam and the detection unit. The cam is configured to be caused to operated by insert manipulation of inserting the manipulation key into the casing when the manipulation key has a shape adapted to a shape of the cam, and not to be caused to operate by the insert manipulation when the manipulation key does not have a shape adapted to the shape of the cam. The door switch can be adapted to Category 2 of ISO 13849-1.

Switch

A control system has an input instrument that generates a signal indicating permission and prohibition of running of a load, a power-supply unit that is configured to supply driving power to the load when the load is permitted to run by an input signal from the input instrument, and to cut off the supply of the driving power to the load when the load is prohibited from running by the input signal, and a monitoring device that is configured to monitor the input instrument and the power-supply unit. The power-supply unit is configured to cut off the supply of the driving power to the load when monitoring result of the monitoring device indicates an abnormality of one of the input instrument and the power-supply unit. The control system is compatible with category 2 of ISO 13849-1.

Control system

Task&#x2014;To provide a two-hand switch device that requires only a small load for each operation cycle. Means to Achieve the Task&#x2014;The device comprises a left hand RF antenna placed in such a position as to enable a communication with the first RFID tag worn on the pre-determined position of the left hand of the worker only when the left hand of the worker is placed in a pre-determined left hand safe position, a right hand RF antenna placed in such a position as to enable a communication with the second RFID tag worn on the pre-determined position of the right hand of the worker only when the right hand of the worker is placed in a pre-determined right hand safe position and an output signal generating means for generating an output signal according to signals received by the left hand RF antenna and the right hand RF antenna.

Two-hand switch device

Task&#x2014;To provide a worker safety management system that can adapt itself to changes in the conditions of the workers and the machines in a flexible manner and can finely manage the safety of the worker. Means to Achieve the Task&#x2014;Worker safety is managed by using safety management information stored in an ID tag. The safety management information includes a work area code indicating a work area permitted to the corresponding worker and a danger avoiding capability code indicating a danger avoiding capability of the worker. The danger avoiding capability indicated by the danger avoiding capability code is determined from a worker skill of the corresponding worker that is evaluated in a standardized manner from past work experience of the corresponding worker and credits earned in a safety education program, and a specific degree of danger in the work area permitted to the worker.
