The 71-266614-12P is a miniature cylindrical connector designed for general-duty applications requiring robust environmental sealing. It operates over a wide temperature range of -55°C to +125°C and supports voltages up to 1000 VAC (RMS) at sea level. The connector is built with resilient inserts that provide high dielectric strength and act as a moisture barrier. Its contacts are machined from a low-loss copper alloy and are gold-plated to eliminate corrosion and provide an indefinite shelf life. Environmental protection is achieved through a grommet and clamp design, making this connector ideal for industrial, military, and aerospace applications where reliability is paramount.
