The Kanban Andon system allows team members to know when a Kanban Card is placed in its slot. The specially designed housing has a built-in sensor that turns the light on when a Kanban card is placed into its slot. It can be run off a standard 110V wall socket or a rechargeable lithium-ion battery. (Battery sold separately)

Contact Types: Normally Open and Normally Closed
Relays and contactors have two types of contacts, each suited for different applications:
- Normally open (NO) contacts allow current when the relay or contactor is energized. In other words, when voltage is applied to the relay/contactor terminals, this contact closes.
- Normally closed (NC) contacts allow current through when the relay or contactor is not energized. When voltage is applied, this contact opens and interrupts current.
Relays and contactors often come equipped with both NO and NC contacts. This makes them more versatile, allowing their use in a wider range of applications. Some tasks are more suitable for NO contacts, while others provide an opportunity to use NC contacts.
