The Edwards 191-7Z-06K-D3 reed switch is a non-contact magnetic interlock and position sensor in the 191 Series GuardSwitch family. First, this is an industrial machine-guarding product — not a fire alarm device. Specifically, the “-D3” variant adds DPST contacts (one N.O. + one N.C.) on a 4-conductor lead. Therefore, this part suits applications that need simultaneous normally-open and normally-closed signaling from a single sensor — for example, both PLC input and safety-relay confirmation.
What the Edwards 191-7Z-06K-D3 reed switch does
This switch senses the presence of a matching magnet actuator without physical contact. As a result, there are no mechanical parts to wear out. In addition, the seamless 304 stainless steel housing resists corrosion from cleaning agents, sanitizers, and food acids. Then both reed contacts change state in unison when the “Z” actuator magnet comes within sensing range.

Part number decode
Specifically: 191 = GuardSwitch stainless-steel series; 7 = base configuration; Z = Z-style magnet actuator; 06K = 6-foot lead; D3 = DPST (1 N.O. + 1 N.C.) contact arrangement on a 18/4 SJTOW lead. For the SPDT 1-N.O. base variant (18/2 lead), see the 191-7Z-06K.
What this switch is NOT
However, the 191-7Z-06K-D3 is not a fire alarm device, a strobe, or a door-holder reed. Therefore, it does not carry UL 268, UL 464, UL 1971, or NFPA 72 listings. Furthermore, it is not intended for life-safety door coordination or smoke-control applications.
