Rugged push-button HMIs now with integrated cables and rear sealing

22 January 2024

EAO Ltd has released details of the latest additions to its rugged Series 82 family of push-button HMIs, which now includes devices featuring vibration-resistant cable connections and rear sealing.

The new cabled versions of EAO’s popular Series 82 pushbutton switches are available with a choice of a 200mm straight or 90° offset cable. They provide significant advantages in terms of mounting flexibility as they can be optimised for a wide variety of applications and mounting scenarios simply by selecting the appropriate connector. 

Variants with the 90° offset cable exit point are particularly useful in machinery with low-depth back panels. The cable version with an M12 connector is impressively robust, easy to mount, and targets demanding machinery applications. 

The cable version with tin-plated cable though offers R118 certification, making it ideal for HMI applications in heavy-duty and special-purpose vehicles. 

All the new devices feature rear over-moulding and IP67 protection as standard while SUS 316L stainless steel casing and enhanced vibration-resistance are available options.
Typical applications
• Food and beverage industry
• Machinery and production facilities
• Heavy-duty and special-vehicles
• Passenger transportation systems and busses
• Access control and security systems
• Ticketing and vending machines

According to Robert Davies, Marketing Manager with EAO Ltd, pushbutton switches and indicators are often exposed to extremely harsh operating conditions: “In the food and beverage industry for example harsh alkaline cleaning agents often cause corrosion problems,” Davies said. 

“Other external factors such as hard-to-remove dirt, fine dust, severe vibrations and blunt impacts can also severely reduce the reliability and lifetime of HMIs. The new additions to the Series 82 family of push-button switches are ideal for use in the most challenging environments.”
