wireless technology drives factory automation changes, reducing costs and downtime

before equipment operation, switches and sensors can be used to detect whether parts, doors and protective devices have been correctly locked. These locks are crucial to ensure the accuracy of production and the stability and safety of equipment operation. However, all wired devices - whether limit switches or proximity sensors - not only have limited use areas, but also are prone to wear and tear, requiring continuous maintenance

at present, proximity sensors are widely used in factories and workshops because they are cheaper than traditional electromechanical switches. However, many manufacturers have found that the proximity sensor requires passive maintenance from time to time, resulting in the interruption of the production process

take multi axis processing as an example (such as engine casting processing), the fixture will constantly rotate the parts to be processed to make them in place correctly, which will make the wire of the proximity sensor continue to move and bear the stress, which will lead to the gradual wear and tear of the cable and finally fracture. Once the cable is broken, the equipment and workers will be idle due to cable replacement (usually it takes 15 to 20 minutes for each replacement). If the cable is replaced every three months (the overall fuel consumption of some new passenger cars (including new energy passenger cars) is reduced to 5 liters/100 kilometers, which is the case for manufacturers), the cumulative productivity loss will be very amazing. If you can predict when maintenance is required, preventive maintenance measures can avoid downtime due to maintenance

similarly, the metal chips brought down by the coolant from the processing area are in continuous contact with the wire, constantly wearing the cable sheath, resulting in "short circuit" or continuity problems. At this time, the cable must be replaced, resulting in the loss of productivity

in addition, one of the biggest problems faced by manufacturers in terms of sensors and equipment is the number of connection points. Each connection point is a potential source of failure. If these connection points are eliminated, manufacturers can reduce the number and time of interruptions in their production processes

all the above problems can be easily solved by using the wireless limit position switch with the only 0.02% cobalt content in China's Cobalt ore. Wireless technology (especially 802. GHz) is a reliable solution, which has been widely used in factories and workshops. Integrating wireless technology into the switch can gain the following advantages: the switch does not consume power, but only plays a control function - which can extend the battery life to two years or more under normal operating conditions. The built-in diagnostic function in RF (radio frequency) circuit can provide low battery indication, and the battery that cannot work normally can be replaced before the workflow is interrupted. This is very important because both the sensor and the RF (radio frequency) circuit consume a lot of power and the battery needs to be replaced regularly

wireless switches can be easily added to applications that use standard wired switches or proximity sensors. Of course, no matter what kind of wireless device is used, RF (radio frequency) signals need to be sent and must be converted into standard input signals (PNP, NPN or relay) available for the control system. This is achieved through the wireless receiver installed in the device control panel. The output of the receiver is directly connected to the controller input card in the traditional wired way. The controller cannot distinguish whether the standard input is from a wireless device or a wired device. The only difference is that additional diagnostic inputs are now added to monitor battery life and signal strength

by reducing the installation cost of switches and providing greater application flexibility, wireless technology has brought a revolution to the field of factory automation. Without cables, manufacturers can significantly reduce maintenance costs, avoid downtime caused by connector and cable integrity, and significantly improve productivity. With the continuous release of new solutions and more applications of wireless technology, the use of wireless devices to solve application problems is bound to lead the new trend of factory automation technology.
