Contact:
Description:
The 348 Series connector provides reliability and high contact density. Qualified to the MIL-C-81511, these connectors can accommodate a minimum of 3 circuits to a maximum of 155 circuits.
Features & Benefits:
- Lightweight, environmentally resistant, and will operate at sea level to a voltage of 600 VAC (RMS)
- It will perform under high-temperature vibration, testing through 302°F (150°C)
- Two basic constructions: Series 1 - Long, Series 2 - Standard; Series 1 features 100% scoop-proof. Series 2, standard connectors are scoop-proof when the pin contacts are specified in the receptacle shell only.
