Access points are transmitter / receivers (transceivers) that connect to a network through an interface such as a bus or connector. They receive, store, and transmit data between the wireless LAN and the wired structure.
Lighting protection systems provide reliable electrical connection to the earth or ground and can vary from simple copper rods to sophisticated electrolytic rod systems with active soil moisture replenishment.
Radio modems are radio frequency transceivers for serial data. They connect to serial ports (RS232, RS422, etc.) and transmit to and receive signals from another matching radio modem.
Sensor mounts, sensor cables and sensor adapters are components specifically engineered for holding/positioning sensors or connecting sensors to sensor systems or instruments.
