    Common handheld terminal devices include mobiles phoness, walkie talkies, PDAs, 4G/5G terminals, etc. These types of devices are often used by personnel entering explosive hazardous areas. They are generally of intrinsic safety type IB or IC, and the temperature rise of the power supply battery and the surface resistance value of the non-metallic shell need to be considered.
