Request Information

The HD-EM1204-SC-R is a 12.4 mm eccentric rotating mass vibration motor optimized for compact devices requiring quick and reliable assembly. Featuring spring contact terminals instead of lead wires, it simplifies PCB integration while still delivering 13,000 RPM at 3 VDC. Its quiet 45 dBA operation and proven durability make it a strong choice for wearable haptics, handheld devices, and pager-style notifications.
