In order to satisfy the demand of market, and promote the development of high-end industry. JINPAT has recently developed a new precision slip ring LPMS-04D with smaller volume than the same industry and level. Body diameter is only 5.5mm, the length is 9.6mm (see chart). It is reduced by about 30% than the original diameter, is the first in the domestic. It breaks the traditional slip ring’s structure that the brush matched with ring, and be suitable for use in harsh environments. We can ensure the mechanical and electrical properties of the product, and can solve greater technical problems that the conventional slip ring quality consistency bias, fluctuations in the value of dynamic resistance between the products do not exceed 3m. It can satisfy the high-quality transmission of aerospace, military equipment, precision medical equipment, robotic and other facilities’ weak signals. In addition, 5.5mm diameter size can meet 10-circuit or less (including 10-circuit) slip ring’s production, simply based on the length of the number of circuits to make appropriate changes. If necessary, please contact us for details.  

The LPMS-04D allows tremendous flexibility in dealing with system size restrictions. It is available in 1-4 circuit configurations.
1.Precision assembly to provide exceptional rotational life
2.Gold to Gold contact provides ultra low contact resistance
3.Speed up to 300 rpm continuous
4. Gold-Gold contacts
5.Superior handling of low level control signals
6. Compatible with data bus protocols
