Slip ring, 12x power (630 V / 25 A) · 155

Our best-selling MIA slip ring – and for a good reason: Four functional power units (each 630 V / 25 A, 3 tracks plus PE) make it a robust solution for demanding power transmission tasks. Whether in crane systems, heavy engineering, or industrial rotary tables, this slip ring performs reliably and without compromise. The mounting flange (Ø 170 mm) enables it to be precisely and stably integrated into your system. With gold-on-gold contact technology and a service life of up to 50 million revolutions, it is designed for long-term continuous operation.

Do you want to adapt the number of functional performance units or add further functions? MIA slip rings can be configured individually – simply contact us.

Like all other slip rings in the MIA series, this version is completely maintenance-free. It is delivered with open cable ends so that you can install the connectors required.

We will provide you with an estimated delivery time upon request. The exact delivery time will be communicated after receipt of order together with the order confirmation.
