SPM special machine slip-ring & cable-reel


                                                      SLIP RING  SR250 SERIES 


The slip ring SR130 assemblies are designed for an operational voltage of max.  680 V.

Depending on the size and the application of the spring-driven cable reel both sliprings for the data transmission

(mA-range / data bus systems) and sliprings for power transmission (up to max. 250A) can be used.

The individually admissible amperages of the slipring assemblies can be gathered from the selection list.

The material of the cover the slip ring is  steel correspond to protection class IP 66

There are two versions:

SR250-B  with 1 1/2" Gas thread connection

SR250 -C1/C2/C3 with flange



UE CONFORMITY : DIRECTIVE 2006/42/CE (-40,+60 C°)

Machine safety according to EN ISO 13849-1 / 2

ELECTRICAL CONTACT SLIP RING

The leaf foil brush system is a particular brush that slides on a surface of a brass or bronze ring.
It has the function of transmitting power electricity, analog and digital signals from a fixed point (brush) to a rotating mobile one (ring) (input = ring / output = brush)

The main advantages of the system are:

1) Compactness and constructive simplicity;
2) Ease of maintenance;
3) Low electrical resistivity values (0.2 <R <6 mohm)
4) Good values of the characteristic impedance of the ring / brush system
5) Low friction value (Good ring / brush smoothness).
7) Low overheating at the contact point.
8) Low overtemperature values of the terminals in case of failure
9) Rapid cooling in case of failure at the contact point
