1. Wiring The design requirements of wiring are very strict in the design of switching power supplies, and they must be done well to pass the test. If the designer does not handle the wiring work in the early stage of design, there will be great safety hazards in the future electricity consumption. So here I recommend you to buy a switching electric ...

(1) Green (HG, GL) What it means: stands for Safety, Normal, Readiness (i.e., an indication under safe operating conditions or the readiness of a mechanical device to start). Function: It is often used to indicate the state of equipment ready to start, all auxiliary components are in a state of preparation for operation, and various parts ...

1. Protection The most important role of the limit switch must be its protection effect, the limit switch is also known as the travel limit switch, which is mainly used to control the stroke of mechanical equipment and limit protection. In practice, the travel limit switch is installed in a pre-arranged position, and the travel limit switch is installed in a pre-arranged position.

First, the characteristics are different 1. Limit switch: The limit switch has the characteristics of small size, multiple functions, high precision, adjustable limit, strong versatility and easy maintenance, installation and adjustment. 2. Proximity switch: The proximity switch has the characteristics of a limit switch, and at the same time has the sensing performance.

The so-called PNP and NPN proximity switches are for the type of DC three-wire proximity switch output transistor, and even though many proximity switch output stages use MOS transistors, they are still called the same. Differences: PNP type proximity switch: The type of proximity switch output transistor is P...

(1) Eddy current proximity switch This type of switch is sometimes called an inductive proximity switch. It is the use of conductive objects when they are close to the proximity switch to produce eddy currents inside the object. This eddy current reacts to the proximity switch, causing the internal circuit parameters of the switch to change, so as to identify the presence or absence of ...

1. If it is installed on metal, a certain space must be ensured to avoid interference between the proximity switch and the metal other than the detection object, resulting in failure. The metal parallel to the sensing surface must be 3 times the sensing distance from the sensing surface. The metal around the shaft of the proximity switch must be outside the cylinder, close to ...

Unmarked/Z: Inductive/inductive self-diagnosis C/CZ: Capacitive/Capacitive Self-Diagnosis N: NAMUR safety switch X: Analog F: Hall V: Reed type J: Threaded cylindrical B: Cylindrical Q: Angular cylindrical shape ...

1. First open all the packages of the newly bought limit switch, confirm that the parts in each package are not missing and complete, and then discharge all the parts in turn. 2. Then open the body part of the limit switch, as long as you loosen the screws with a screwdriver.
