OverviewThe ES Series electrical slip ring is a rotating assembly for transferring analog and digital signals, control circuits and data from stationary inlets to rotating outlets. The compact capsule design features low torque, gold-on-gold contacts and flexible color-coded lead wires. Standard models cover 6 to 56 circuits, with seals for light dust and splash protection and an optional IP65 enclosure for full dust/water protection. Combined fluid-and-electrical integrated packages are available on request.

Notes on Data TransferSuccessful digital data transfer depends on signal levels, cable type/length, grounding and shielding. For high-speed or Ethernet applications choose Ethernet-capable series (ESE / ESET) or consult engineering for compatibility and approvals.
