These enclosures consist of high-impact ABS (operating temperature : -4°F to +212°F). The lid and the base equipped with a tongue and groove sealing system with a neoprene gasket. The mounting holes and the lid-fixing screws are outside the seal, which prevents moisture and dust from entering the enclosure. Internal guide slots allow the vertical mounting of PCB assemblies.
