Shock resistance

100G shock resistance achieved
by adopting a plunger-type electromagnet design

Conventional “hinge type” supporting the contact movable part via a line contact: The structure being simply pressed sideways by the spring force will move when subjected to a shock exceeding the specified limit. T-shaped contact movable part “Plunger-type” structure adopted for G9EK: Less susceptible to vibrations coming from directions other than the contact’s movement direction (left, right, front, or back). Solenoid: The magnetic force of the solenoid coil generates high contact pressure, and the structure is highly resistant to vibration.
