Normally Closed Signal Safety Edge/Safety Mat/Impact Switch

The normally closed signal safety edge has a self checking function, which can effectively detect short circuits and avoid other problems caused by safety edge failure. It is a good choice. Safe edge contact is applied in multiple scenarios such as AGV cars, elevator doors on both sides, unmanned vehicles, sweeping and cleaning robots, etc. It plays a protective role and is the last line of defense for safety assurance!

So how to choose between normally open or normally closed signals?
According to customer needs, the safety edge protection with normally open signal is quite common in the market and is the earliest form of edge protection. However, normally open does not have a self detection function. When the safety edge is disconnected, it cannot send a signal to inform people that the safety edge is damaged, and the market price is relatively low; However, the normally closed type has a self detection function. When there is a problem with the edge connection, it can immediately signal a fault and replace the safety edge with a new one, which is slightly more expensive than the normally open type safety edge. So the specific choice needs to be based on your own usage needs. We can provide suitable product signal output according to your application scenario, and we can customize various sizes and shapes based on your drawings.
