Add it to your cart or contact us for further assistance.FAQHow does the normally closed (NC) contact work with this module?The normally closed (NC) contact configuration means that the circuit is complete (closed) in its default state. When an action occurs (e.g., a button is pressed), the contact opens, breaking the circuit. This is ideal for safety interlocks and monitoring applications where a break in the circuit indicates an event or issue.Are special tools required for wiring the spring-type terminals?No, the spring-type terminals are designed for quick and tool-free wiring. This streamlines the installation process and reduces maintenance efforts.What does the IP40/IP20 protection rating signify?The IP40 rating for the enclosure indicates protection against solid objects larger than 1mm, meaning it's safeguarded from most tools and wires. The IP20 rating for the terminals means they are protected against solid objects larger than 12.5mm, like fingers, but are not protected against liquids. These ratings ensure operational safety and longevity in appropriate industrial settings.
