Compact Frames for Tight Envelopes
At 18 g and 1.6 W continuous, the SH-0520 is one of the smallest continuously-rated frames in the range; the SH-0530 stretches the same width to a longer body for more coil. These frames suit devices where the solenoid must disappear into the mechanism: smart locks, small appliances, and handheld equipment.

Force-Stroke Behaviour
Force is not a single number: it changes along the stroke, and each duty-cycle rating has its own curve. The full force-stroke chart is in the datasheet page below. When you specify, state the force you need at the working point of the stroke, not just the peak. Our guide to reading force-stroke curves and duty ratings explains the common selection traps.
Typical Applications
Smart locks, household appliance latches, fitness equipment, small dispensing mechanisms and compact automation.
SH-0520 or SH-K0520?
The K prefix matters: SH-K0520 is the latching (permanent-magnet holding) version in the same frame size. Choose the K version when the mechanism holds position for long periods with power off; choose this continuously-rated version for frequent actuation.
