Terminal blocks, headers, plugs and sockets form a quintessential electrical connection system. The mechanism is such that the connection points are modular, allowing for maximum versatility, eliminating the requirement of specialized hardware for individual devices. In the case of the NB02A0850000G, it is a terminal block connector with two screw terminals from the popular N-series range of Phoenix Connectors.

Offering two pole voltage connection, this unit is designed to terminate solid or stranded round, with a 0.25–2.5 mm² wire size. It can be mounted onto 35 mm DIN rail for easy installation and can be used for panel mounting. The contacts are made from alloy alloyed copper and are pre-assembled with marked polarity, making them ideal for electrical control circuits. The external brass screws being captive ensure reliable and secure wire connections.

Viewed from its component parts, the NB02A0850000G incorporates Philips M2 steel screws instead of standard aluminum screws for better resistance to corrosion. The screw head features a recessed shallow designs for easier assembly, and metal armor that offers superior shielding from external magnetic fields. One of the protruding acrylic contacts on the terminal block is in fact part of its vibration proof construction as it absorbs the impact of variable forces, further improving the durability of the connection.

The NB02A0850000G’s application field includes quick and simple Terminator Blocks Panels, Controllers, Automation System, Telecommunication Equipment, Power Supplies, Industrial Automation and other applications that require secure connections and improved durability. It can operate under specified criteria in temperatures that range from -20°C to +85°C and up to 10A, 24V DC.

As for its working principle, the straightforward implementation of the NB02A0850000G involves inserting the wires into the open terminal block barrels, twisting down the captive brass screws, ensuring a secure connection. As mentioned earlier, the orientation of the connection points are marked, as the screws don’t offer polarized connection; hence precise grounding is engaged through note on the wiring diagram or the presentation of the panel with clear visual cues.

For resetting the connection, merely unscrew the head screws and the wire is released from the terminal blocks. Commonly this terminal blocks come in series from 2 to 8 poles, and can be connected amongst then using a special jumper link. To this end, the NB02A0850000G fulfills the need for a reliable electrical connection system with no need for specialized hardware for individual devices.
