The power supply to the sensor or the data module can be interrupted without contact when the tool holder is removed from the machining space of a machine tool. This prevents, for example, the power supply from being discharged while the tool holder is in a magazine outside the machine, and, for example, significantly increases the availability and service life of the tool holder before a battery is replaced, and/or before the accumulator and/or charge storage device is recharged. ## Claims ### Claim 1 A tool holder comprising: a receptacle for a tool; a data module; a power supply, wherein the data module has at least one sensor configured and/or programmed to capture operating and/or status data, and a transmitter configured and/or programmed to transmit the operating and/or status data to a receiver; and a switching unit is capable of electrically connecting or disconnecting the data module to or from the power supply, wherein the switching unit is designed in such a manner that the switching unit is actuated without contact, the switching unit is a reed switch, and the reed switch is designed to be actuated by a magnet located outside of the tool holder. ### Claim 2 (depends on 1) The tool holder according to claim 1, wherein the reed switch is designed as an opener or as a changeover contact. ### Claim 3 A tool holder comprising: a receptacle for a tool; a data module; a power supply, wherein the data module comprises at least one sensor configured and/or programmed to capture operating and/or status data, and a transmitter configured and/or programmed to transmit the data to a receiver; and a switching unit which is capable of electrically connecting or disconnecting the data module to or from the power supply, the switching unit is designed in such a manner that the switching unit is actuated without contact, the switching unit comprises an electrically actuatable switch, and the switching unit is supplied wirelessly with electrical energy by a transmitter located outside of the tool holder. ### Claim 4 (depends on 3) The tool holder according to claim 3, wherein the switching unit comprises a receiver configured and/or programmed to receive the electrical energy emitted by the transmitter, by means of electromagnetic waves. ### Claim 5 (depends on 3) The tool holder according to claim 3, wherein the data module has a rotation speed or angle of rotation sensor, at least one temperature sensor, an acceleration sensor, a microphone, and/or a sensor for capturing the charge status of the power supply. ### Claim 6 (depends on 3) The tool holder according to claim 3, wherein the data module comprises an evaluation unit for evaluating and/or processing the data captured by the at least one sensor. ### Claim 7 (depends on 3) The tool holder according to claim 3, wherein the data module comprises a storage unit for storing the data captured by the at least one sensor and/or the data evaluated or captured by the evaluation unit. ### Claim 8 (depends on 3) The tool holder according to claim 3, wherein the data module and the power supply unit are accommodated in the housing of the tool holder and/or in a separate housing. ### Claim 9 (depends on 8) The tool holder according to claim 8, wherein the housing of the tool holder or the separate housing has a cover. ### Claim 10 (depends on 9) The tool holder according to claim 9, wherein the separate housing and/or the cover consists of a non-ferromagnetic material. ### Claim 11 (depends on 3) The tool holder according to claim 3, wherein the power supply unit is an accumulator and/or charge storage device. ### Claim 12 (depends on 11) The tool holder according to claim 11, further comprising: a nanogenerator or a generator, wherein the nanogenerator or the generator is configured and/or programmed to charge the accumulator and/or charge storage device. ### Claim 13 (depends on 12) The tool holder according to claim 12, wherein the nanogenerator or the generator at least partially supplies the data module with electrical energy during operation. ### Claim 14 (depends on 11) The tool holder according to claim 11, further comprising: a receiving coil; and a rectifier, wherein the receiving coil is designed for coupling to a transmitting coil situated outside of the tool holder for the purpose of inductively charging the battery and/or charge storage device. ### Claim 15 (depends on 3) The tool holder according to claim 3, further comprising: a housing and/or an additional housing, wherein the data module and/or the power supply are accommodated in the housing or in the additional housing. ### Claim 16 (depends on 3) The tool holder according to claim 3, further comprising: a plurality of modules.
