Oyster Bay, NY —Mill-Max is expand- ing its spring-loaded solder cup con- nector series with new versions that deliver over 60 percent more stroke than the existing series. The single- row 824-22-0XX-00-005000 and dou- ble-row 826-22-0XX-00-005000 pro- vide a mid-stroke of 0.045 in. (1.14 mm) and a maximum stroke of 0.09 in. (2.29 mm). The longer stroke helps compensate for tolerance stack-ups in assemblies and offers greater flexibili- ty for unpredictable motion due to shock and vibration. The 824 and 826 series headers
contain the new 0947-0-15-20-77-14- 11-0 spring pin, utilizing Mill-Max’s popular 0.09 in. (2.29 mm) maximum stroke spring. Each pin in the connec- tor provides a mid-stroke force of 60g (2.12 oz), a solder cup sized to accom- modate up to a 22 AWG wire and a current rating of 2A continuous use (3A max). The high retention force press-
fit of the solder cup to the body of the spring pin ensures the reliability of the component during soldering and assembly. Uniform orientation of the solder cups makes it easy to solder cables or discrete wires to the spring pins, eliminating the need to manip- ulate the wires or the connector to solder each wire. The spring-loaded assemblies
are an excellent interface solution for discrete wire-to-board, cable-to- board or cable-to-cable applications. The connectors are made with high- temperature nylon 46 insulators,

have 0.1 in. (2.54 mm) pin spacing and are available from 1-64 positions in single-row and 2-72 in double-row. Gold-plated, precision-machined brass components and beryllium cop-
per springs provide high conductivity, corrosion resistance and durability. The spring-loaded plunger is suitable for mating with gold-plated PCB pads or Mill-Max target pins and connec-

tors. The company offers a complete line of target connectors to act as the mating surface for the spring-loaded plungers.
Target connectors are available
in through-hole and SMT (319 series single-row, 419 series double-row), right-angle (399...10-008 single-row, 499...10-008 double-row) and with solder cup terminations for cable-to- cable applications (330 series single- row, 430 series double-row). Discrete target pins and disks are also avail-
able as standard options. Contact: Mill-Max Mfg. Corp.,

Converters
Paterson, NJ — Polytron Devices has launched two new DC-DC converters for use in industrial applications. The QB100 and QB150 series have 100 and 150W ratings, respectively, as well as a 4:1 wide input range.
Quarter-brick industrial DC-DC converter.
The QB100 series offers high effi-
ciency, up to 93 percent, and comes in a compact 2.3 x 1.5 x 0.5 in. (5.8 x 3.8 x 1.3 cm) quarter-brick package. The QB150 series, available in the same size, offers efficiency up to 92 percent. Both devices require no mini-
mum load and have 2250 VDC input- to-output basic insulation. They are RoHS II and Reach-compliant and meet UL60950-1, EN60950-1 and
IEC60950-1 safety standards. Contact: Polytron Devices, Inc.,
