SERIES - RA and RNSERIES RA - 2- and 3-conductor RA Jax® are designed with split terminals which provide two distinct advantages over contemporary jacks:
1. Positive retention of jack in PC board during wave soldering.
2. Split terminal permits additional solder flow paths up the terminal for better mechanical/electrical connection
Tip spring design facilitates positive retention of differing mating plug tip shapes (industry standard and others).
SERIES RN - Right-angle Hi-D Jax® permits space-saving mounting on PC boards. Available in 2- and 3-conductor types with or without shunt circuits, which can mate with .25 inch diameter COMMERCIAL or TELEPHONE/MIL plug fingers. Right-angle jack permits tip of mating plug to be inserted parallel with PC board. Can be mounted on PC boards or combined PC board and panel/chassis.
Mounted through .375 inch diameter holes (locknut and washer supplied) in panels and chassis up to .141 inches thick. Minimum mounting centers are .625 inches. If insulated mount is desired, mounting with flat, non-conductive washer (not supplied) is recommended.
PC terminals mount on boards up to .125 inches thick, and hand dip or wave soldering, is recommended. Three separate standoffs fit through board to provide stable mounting.Threaded bushing permits optional fastening to panel or chassis.
SERIES RN110 - 2- and 3-conductor right-angle types mount in PC boards or panel/chassis. Bushing is
.278 inches long.SPECIFICATIONS
Housing: Thermoplastic.
Bushing: Integral with housing.
Springs: Copper alloy, silver-plated (also available with
selectively gold-plated contact points and selectively
tin-plated terminals).Contacts: Integral, part of shunt springs.
NOTE: Specifications for Mechanical, Electrical and Environmental are the same for Hi-D® Jax. (page 87)
