Inmoco’s SRH 80180 and SRH 90195 series slip rings are suitable for use in video systems, robots and downhole inspection equipment and manufacturing and process control systems, for example.

The new 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.

This also includes filling machines, medical equipment and packaging machines.

Both series of SRH slip rings deliver a flexible and cost-effective solution, according to the company.

Offering 80mm and 90mm internal diameters respectively, allowing cables and pipes for other services to be routed through them, the 80180 and 90195 slip rings are available in many standard configurations.

They offer a high rating life of 20 million revolutions (nominal speed of 250rev/min) and a facility of six to 96 circuits, with up to 216 as an option.

Their optimised size enables installation into compact systems, while a combination of low friction torque, high insulation resistance and tough ABS housings is designed to ensure a high operating reliability and a long life.

The design of the SRH series slip rings allows low peripheral speed between brushes and rings, as well as reduced dynamic imbalance; these factors equate to low wear for the user.

Thanks to the use of noble metals and a new technology that allows multiple contact points between bushes and ring, electrical noise and interference between circuits are reduced and low-contact electrical resistance is guaranteed.

All of these features make the SRH series suitable for the transmission of critical signals, such as high-frequency signals (including video and fieldbuses) and low currents and voltages (such as strain gauges, thermocouples and measuring equipment).

Both SRH series are available for use with 600VAC/VDC voltages and currents to 15A (20A optional); they are IP51 protected (IP65 optional) against the ingress of dust and dripping water and offer an operating temperature range of -40C to +80C.

The slip rings can be customised upon demand, in terms of the number of circuits available from the SRH units, and offer both flying lead and PG gland connection options.
