The WC-42 conforms to EU requirements of low voltage yokes for dangerous environments. Other than the Power Supply, these units are identical to the WC-6 and has the same compact design, articulating legs and a durable power cord strain relief that can be directed up or down that allow this yoke to be adapted to confined spaces and almost any test part. A Urethane Rubber housing provides superior durability in rugged environments. The ergonomically designed grip, combined with WC-Series lightweight design, reduces operator fatigue and strain which permits longer and more thorough inspections. The WC-42 uses a low profile sealed membrane activation switch which ensures operator safety with a grounding provision and conducts less than 1/2 watt of power.
