New Yorker Electronics has announced the addition of a new series of NEMA 5-20 snap-in power entry connector receptacles for use in medical and industrial instrumentation. Available in two sizes, the ganged female sockets are used in power strips, power distribution units, portable power devices and almost anywhere additional power is needed.
These Power Dynamics Inc. (PDI) Snap-In Connectors are designed for compact applications with only a 26.5 mm width and snap into 1.0 mm through 2.0 mm panel thicknesses. A strong cord retention/withdrawal force and a heavy duty nylon body make it ideal for rugged applications. It can be

The PDI-520R2-3121 3-Gang NEMA is 79.6 mm x 26.50 mm and the PDI-520R2-4121 4-Gang NEMA is 107.76 mm x 26.50 mm. They are both rated at 20 A, 125 V AC with an operating temperature range of 0° C to 65° C. The housing is constructed of black UL-94V-0 rated nylon-6 with tin plated terminals. They have a panel thickness range 1.0 mm to 2.0 mm and they both accept NEMA 5-15P and 5-20P plugs.
The 3121 and 4121 require a withdrawal force of 1.3 kg to 6.7 kg. Initial contact resistance is 10 MOhms (maximum) and its insulation resistance is 100 MOhms (minimum) at 500 V DC with a dielectric withstanding voltage of 2000 V AC for one minute.
