Product DetailProduct Description
Robust safety limit switch with metallic housing. Direct opening mechanism in both of slow action type, and snap action type
[Features]
· Direct opening mechanism (only at NC contact side) to separate contact at the time of fault in contact welding.
· Safety of lever setting is achieved by using operation position display board and mechanism by which lever is interlocked.
· Proper operation zone display mechanism is also available.
· Moreover, changing of direction of lateral movement is also by one-touch.
· Improvement in sealing property by strengthening the seal structure of head part (meets TÜ V: IECIP67, UL: NEMA3, 4, 4X, 6P,13).
· Wide available temperature range of - 40 to +80°C.
· Approved by UL, CSA, EN(TÜV), CCC
Dimensional Drawing of OMRON Limit Switch
Note: The dimensional tolerance of the parts not specified in the above external dimension diagrams for each model is ±0.4 mm.
*1. The lever can be fixed at any position by inverting the set position indicator plate.
*2. In terms of mechanism, it is not a safety Limit Switch but a general Limit Switch.
