Rack and panel connectors mix power and signal contacts to increase applications

30-08-2019 | Lane Electronics | Connectors, Switches & EMECH

A rack and panel connector system which gives users an almost 'limitless' variety of pin configuration is offered by Lane Electronics. Called Scorpion and manufactured by Positronic, it can be configured for usage as a power or signal connector or as a mixture of the two.

According to Lane’s Nick Wheeler, Positronic’s Scorpion is possibly one of the most versatile modular power/signal connector systems on the market. He says: “In essence, engineers can specify any configuration they wish, from any number of power and signal modules as well as a range of guide and locking arrangements. All this and any combination from just one module to many up to a maximum connector length of 101mm.”

The Positronic Scorpion Series of rack and panel connectors is offered in various formats incorporating board to board, cable to cable, or board and panel to cable or board. Blind mate is a feature and also the integral locking system on the cable connector option.

Contacts are provided in crimp, straight and 90-degree solder as well as straight press-fit (solderless) PCB termination. Users can also specify Positronic’s proprietary PosiBand contact which overcomes the weaknesses inherent in the design of many closed entry female contacts currently in use by several connector manufacturers. The contact is a true closed entry contact with an unbroken ring of solid material right at the face of the contact.

This is said to offer higher reliability levels as the PosiBand contact gives a greater surface area at the female/male contact interface. It needs a lower insertion force, which is particularly important in high-density connector systems and highlights very low contact resistance levels. The Posiband contact is offered for contacts #22, 18, 16 and 12.

With a height of only 14.6mm, users can specify housings with optional ventilation slots for enhanced cooling and sequential mating limits the number of connections that go 'live' at the same time.
