Mercury Slip Ring adopts liquid metal mercury as its current transfer medium. Thanks to its special sealing technique, insulation design and compactness, Mercury Slip Ring has outstanding characteristics like long life span, extremely low electrical noise and contact resistance. Besides, this kind of slip rings is able to transfer large volume of current regardless of its compact size while remaining a low cost.

Despites its impressive advantages, Mercury is chronic toxic substance. In case a leakage occurs, it will pose a huge threat to both the environment and the health of operators. As a result, people are actively seeking substitutes for mercury slip rings.

Through combing conventional brush/shrapnel and copper rings within its compact size comparable to the Mercury slip ring, Pin Slip Ring emerges in such background. Just like mercury slip ring, pin slip ring substitutes copper pins/rings for outlet wires, and is plug-in assembled in an electric system. Pin Slip Rings, designed and manufactured by JINPAT Electronics, is available in 2~8 channel models. The number of its channel is based on the mercury slip rings; therefore our pin slip ring series has one-to-one replacement solution for different mercury models.

JINPAT Pin Connection Slip Ring, except for its 2-channel model, generally blends 5 A, 10 A, 15 A and 20Acircuits. Of course, customers can request specific combinations according to their needs, with the model’s single channel current capacity reaching up to 50 A. This slip ring model has a life span over 5000 revolutions with a working speed up to 300rpm. It applies to 240VAD/DC circuit with a dielectric strength no less than 500VAC@50Hz, insulation resistance over 100MΩ@500VDC.   Furthermore, with an initial protection level of IP 54, it can work in the environment with a humidity less than 60% and an ambient temperature +40℃~+80℃. JINPAT Pin Connation Slip Ring, with its gold-to-gold contact and copper plated insert (pin) demonstrates excellent electrical performances.
