What are the main parameters of the switch?

The main parameters of the switch

Rated voltage: refers to the safe voltage allowed by the switch during normal operation. If the voltage applied to both ends of the switch is greater than this value, it will cause ignition and breakdown between the two contacts.

Rated current: refers to the maximum safe current allowed to pass when the switch is turned on. When this value is exceeded, the contacts of the switch will be burned due to excessive current.

Insulation resistance: refers to the resistance value of the conductor part and the insulation part of the switch. The insulation resistance value should be above 100MΩ.

Contact resistance: refers to the resistance value between each pair of contacts when the switch is turned on. Generally, it is required to be below 0.1-0.5Ω. The smaller the value, the better.

Withstand voltage: refers to the highest voltage that the switch can withstand between the conductor and the ground.

Life: refers to the number of times the switch can be operated under normal working conditions. Generally, it is required to be about 5000-35000 times.

Overview of photoelectric switches

The photoelectric switch is a member of the sensor family. It converts the change in the intensity of light between the transmitting end and the receiving end into a change in current to achieve detection purposes. Since the output circuit and input circuit of the photoelectric switch are electrical...
