Eaton Push Buttons
Eaton Push Buttons are recognized for their robustness and adaptability to challenging industrial environments. This durability is a result of their design which can withstand factors like exposure to dust, moisture, and rigorous use.
Eaton has introduced multiple product lines or series of push buttons such as the M22 and HT800, among others. Each series boasts unique features catering to specific applications or environmental needs. There are both basic and more sophisticated illuminated versions in their collection. The illuminated models serve multiple purposes, such as providing visibility in low-light situations or indicating operational statuses.
The configuration of these push buttons varies extensively. Some are designed for momentary actions, while others support maintained actions. You'll find options ranging from single to double-headed buttons, with diverse colors to aid in differentiation.
Maintaining NEMA 4 Rating When Making Enclosure Penetrations
Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.
Devices mounted to the enclosure must have the same NEMA rating as the enclosure.
This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure.
Water tight conduit hubs must be used when running wire through a cutout in an enclosure.
There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.
Bonded washers are necessary when mounting hardware to an enclosure.
If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
