Project Description
Overview
This engineering firm needed a custom keypad to replace its existing product used on a commercial Reach/Forklift Truck. The requirements were very demanding including very stringent ergonomic requirements for actuation, severe operating temperature extremes, and product life/actuations. The keypad would be used for industrial cold storage warehousing where the vehicle would go in and out of a -40° F warehouse onto the loading dock that could reach 100° F with high humidity. Based on the daily usage, carpal tunnel syndrome was a concern and 3 million actuations was the common life span.Challenges
