Welker Z World Switch Welker L3 Cylinder Switch

Welker Z World Switch

NEW! Welker is pleased to offer the Z World Switch, an economical option now available on many standard products. The Z switch is an inductive sensor with extremely bright triple luminous band indication. Ideal for use in harsh environments, such as direct- and alternating-field welding systems.



Welker L3 Cylinder Switch

The Welker L3 solid state cylinder mounted sensor is immune to the majority* of direct and alternating field welding applications. Interchangeable with World Switch in function and performance. Mounts easily to T-slot and tie rod cylinders. Weld spray resistant cable covers.


*Note that some mid and low frequency DC resistance applications (i.e. aluminum resistance welding applications) may cause a fault. In these applications, it is recommended that the sensor be ignored/bypassed during the welding cycle.
