Product Description:

The H42RCFC-LNK-NS-00 is a hybrid stepper motor manufactured by Kollmorgen within the H Hybrid Motors series. This NEMA frame device serves as the actuating element between an electronic motion controller and the mechanical load, turning digital pulse trains into predictable shaft positions without requiring a feedback transducer. Its coarse-to-fine step capability allows controlled advances in packaging, semiconductor handling, and modest conveyance tasks where moderate speed and precise detent torque are necessary.

In mechanical terms, the frame conforms to NEMA 42 and uses a square mounting face with a 3.000 in bolt circle and #10-32 UNC-2B threaded holes for direct panel or gearbox attachment. Internally, a laminated rotor works with dual stacks to generate 200 full steps per revolution, with each increment measuring 1.8 degrees. Electrical endurance is supported by an insulation system rated Class B, 130 °C with 100 megohms of insulation resistance, and the windings can withstand up to 340 VDC without dielectric failure. A pilot diameter of 2.186 in centers the housing, and concentricity across the smooth shaft is maintained during coupling.

For external wiring, the motor uses a System MS connector with an 8-lead configuration, and the mating plug is MS3116F14-12S so phase, common, and tap conductors can be rearranged for full- or half-coil current modes. The output shaft has a diameter of 0.6250 in and is machined without keyways to suit clamp couplings. Positional repeatability is reinforced by a step accuracy of ±1.5%, helping commanded motion stay within tight angular limits. Continuous service is specified from -20 °C to +40 °C, matching many control-cabinet environments. The standard construction maintains magnetic stability and shaft concentricity during operation.
