Economy Power Connector System
TE Connectvity’s (TE) Economy Power (EP) wire-to-board connector family is widely used for power circuit
applications. Based on the proven EP version the new and advanced EP II and EP 2.5 lines oer additional
benefits. EP II connectors are rated for 600VAC at up to 11A and thus oer potential for a larger range of
applications. Still their electric properties make it an option to mix signal and power in one connector.
EP II connectors oer two levels of mechanical and electrical reliability: A true locking latch prevents
the plug housing and post header from vibrating apart, while a Terminal Position Assurance (TPA) device
produces a tangible click once a receptacle contact is fully seated. A visual aid confirms that the contact
is home plus it provides easy access to a probe tip for continuity testing. The new EP 2.5 family is a
compact version based on a .100” [2.5mm] pitch ideally suited for PC board space restraints. Up to
20 positions make it the perfect choice for combining power and signal.
