DF-4 System Description
• A new industry standard at the point of lead-pin to device-port connection • four poles of electrical contact on an inline connector, • reduces bifurcated and trifurcated lead-device connectors into a single connection • single pin-to-port connection for a high power lead instead of two or three connections.
