Things About Cam Switches in Automation Control

Cam switches are old players in the field of automation. They are like a mechanical version of a smart switch, which is responsible for triggering different control actions according to the movement position of the machine. For example, in a PLC control system, it can accurately detect the angle at which the equipment is running, and whether to open or close the gate is entirely up to it.

Today's digital cam controllers are more advanced. For example, Beckh off's MC_Digital Cam Switch can not only control the switch state, but also predict the exact time of the next switch action, which is particularly suitable for flying control scenarios that require ultra-high precision. Some models also support multiple cam tracks, and one controller can handle the timing control of the entire set of equipment.

The LW39 series universal conversion switch commonly seen in factories is a typical application. Through the combination of cams in different gears, it can control complex operations such as forward and reverse rotation of the motor and multi-speed adjustment. It is much more durable than ordinary relays, has a simple mechanical structure and is not afraid of electromagnetic interference.

If you want to say that its most powerful ability is that it is very good at converting mechanical motion into electrical signals. Whether it is positioning detection on an automated production line or timing action of a packaging machine, it is impossible to do without it. Although many occasions are now replaced by sensors, the reliability of this pure mechanical device is still irreplaceable in harsh environments.
