For non-hazardous, heavy-use applications with >100,000 actuations, EOA’s Series 51 stop switch has a back panel depth of just 18.8 mm. It is well-suited for interfaces that require a visible actuation status. Using a monoblock design, the stop switch is sealed to IP65 standards from the front of the panel. It utilizes an industry standard 16 mm mounting hole, and meets many international standards, including CE, EN 61058-1, and RoHS environmental requirements. Solder, quick connect, and PCB terminals, along with a variation of NO and NC contact configurations, add to its versatility. Initially available in a low signal level switching element with 2.0 mm plug-in, solder, or PCB mount connection, the Series 51 provides a single-break momentary contact switch system with two contacts per switching element, and a combination of NC and NO contacts.
