Inmoco has extended its Servotecnica range of commercial slip rings with the addition of two new highly robust series that offer the flexibility for up to 96 connections, (216 upon demand), plus high voltage/current operation, low temperature working down to – 40 degrees C, and the ability to operate at speeds up to 800rpm.

The new SRH 60135 and SRH 70155 series slip rings are designed for use in any system requiring the transmission of electrical and/or power signals to an intermittently or continuously rotating shaft. Typically this includes equipment as video systems, robots and downhole inspection equipment, manufacturing and process control equipment, filling machines, medical equipment and packaging machines,

Both series of SRH slip rings deliver a flexible, cost-effective, reliable and high-quality solution. They are available in many standard configurations; offer a high rating life of 10 to the power of 7 revolutions (nominal speed 250rpm) and the facility of from 6 to 96 circuits, with up to 216 as an option. Their reduced size – the SRH 60135 is the smaller of the two - allows installation into compact systems, while a combination of low friction torque, high insulation resistance and a tough ABS housing guarantees high operating reliability and long life.

The design of the SRH series slip rings allows low peripheral speed between brushes and rings, as well as reduced dynamic imbalance; combined these factors mean low wear for the user. Moreover, thanks to the use of noble metals and to a new technology, which allows multiple contact points between bushes and ring, electrical noise and interference between circuits is reduced considerably, and low contact electrical resistance is assured. 

All of these features make the SRH Series ideally suited to the transmission of critical signals, such as high-frequency signals (video, fieldbuses etc.), very low currents and voltages (strain gauges, thermocouples and measuring equipment).

Both SRH series are available for use with 600Vac/Vdc voltages; they are IP51 protected (IP65 optional) against the ingress of dust and dripping water, and offer a wide operating temperature range: -40 degrees C to +80 degrees C. In addition, the SRH series can be easily customised upon demand, in terms of connector types and cables, and also the number of circuits available from the SRH units.
