The NEC/TOKIN EP2 Series automotive relays datasheet provides specifications, dimensions, coil ratings, and part numbers for the EP2 relay family.
The EP2 series automotive relays feature a twin‑relay design for motor and solenoid reversible control, offering up to 30 A contact switching current and a compact footprint that saves 50 % of space compared with conventional two‑relay solutions. They are supplied in stick‑tube packaging for automatic insertion machines, with a wash‑able type also available.
Key specifications include contact resistance values as low as 3.2 mΩ, operate and release times of approximately 5 ms and 7 ms respectively, insulation resistance of 100 MΩ at 500 Vdc, and an operating temperature range of –40 °C to +85 °C. Mechanical life expectancy is rated at 1 × 10⁶ operations, and electrical life at 1 × 10⁵ operations under specified load conditions.
