Barrier Terminal Block
Terminal blocks are used to facilitate the connection of wires. In fact, they are a piece of metal sheet sealed in insulating plastic. There are holes at both ends to insert wires and screws to fasten or loosen them. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and can be disconnected at any time without having to connect them It's very convenient and fast to weld or wind together. And it is suitable for a large number of wire interconnection. In the power industry, there are special terminal blocks, terminal boxes, all of which are terminal blocks, single-layer, double-layer, current, voltage, common, breakable, etc. A certain crimping area is to ensure reliable contact and enough current.

On Friday, May 26, 2017, it is understood that Naray Technology is currently developing a new security radar, measuring target distance (pedestrian) to more than 300 meters, using digital beam synthesis technology, and continuous optimization, the detection distance will be more far.
What is Digital Beam Synthesis (DBF) technology?
The concept of digital beamforming comes from the adaptive array antenna technology used by military radar and sonar. It makes full use of the spatial information obtained by each array element of the array antenna, and realizes beamforming, target tracking and spatial interference signals through signal processing technology. Zero. The advantages are: single or multiple independently controllable beams can be formed without loss of signal to noise ratio; beam characteristics are controlled by weight vector, flexible and variable; antenna has better self-correction and low sidelobe capability; Signal processing for excellent performance. It was once called "the radar technology of tomorrow."
The concept of digital beamforming technology has been proposed by VanAtta since 1959. It has been in development for more than 50 years and can be divided into five stages: 
What are the advantages of Naray's Digital Beam Synthesis (DBF) technology?
Digital multi-beam radar compared to traditional single-element radar:
Multi-beam radar has strong angular resolution to the target and can distinguish multiple targets with close angles.
For the same target detection range, the digital multi-beam radar has much less transmit power than a single array element. In other words, for the same transmit power, the multi-beam radar system can detect the farthest target distance greater than the single-element radar.
