| | | The D4NH hinge safety switch and the D4GS miniature safety key switch are designed for use with safety industrial doors that form the entrance to protected areas in production systems and machines. The heads of both switches can be mounted in different positions for installation flexibility. | | The D4GS has a special third contact that enables it to be used as a cross-fault safety switch for category 4 applications. Its very compact dimensions make the D4GS ideal for use where space is limited, and its IP67 rating makes it suitable for operating in extreme environmental conditions. | | |
