Long Life Linear Solenoids for PCB Applications
The ZST1624N Long Life series of linear solenoids has been designed to meet the requirements of demanding applications where PCB mounted solenoids with up to a million actuations are required. Additional features include extended operating temperature ranges of -35°C to +66°C, and footprints as small as 0.95" length by 0.72" diameter.
Continuous duty configurations are available with forces up to 1.75lbs. @ 0.010" and 0.15 lbs. @ 0.060" with an overall unit weight of 2oz. Stroke lengths up to 0.060" can be accomodated. Class F insulation systems are standard. PCB mounting pins are standard.
Long Life solenoids are well suited to mission critical AC or DC applications such as physical security, circuit protection and fault detection. Prices are below $3 in high volumes.
