M12 eurofast ac/dc junction box from Turck features an integrated dc supply that allows the use of dc sensors in ac applications.

Minnetonka , MN —M12 eurofast ac/dc junction box from Turck contains an integrated dc power supply that lets dc sensors be used in ac applications. The 4-port junction box simulates a 2-wire ac sensor said to achieve a cost-effective method that is easier than installing a separate power supply and relays.

DC sensors reportedly cost less than ac sensors. Use of the more prevalent dc sensors in more applications can also reduce sensor stock levels. The ac/dc junction box offers 85 to 132-V ac input, 100 mA output per port, and 24-V dc output to PNP short-circuit protected sensors only. A die-cast aluminum alloy, fully encapsulated housing provides IP67 protection when all ports are connected or covered with closure caps. A 7-pin “minifast” connector provides quick connection.
