Customize Guide for Linear Push Pull Solenoids / Latch (Keep Hold, Bistable ) Solenoids / Dual Latching Solenoids

1. What product do you use solenoid for? to pull or push when power on? (latching when power off?)
2. Force/Stroke (Pull or Push distance) needed?
   Prime output. Force drops sharply while stroke goes longer, so design stroke needed as short as possible.
3. Power (Max.) on time / off time (Duty cycle, ED%)?
   Solenoids heat up when power on, heat sinks when power off. Balancing with power to avoid overheating.
4. Power supply: volts DC or AC? Stable? Any limits on watts or amps?
   
5. Return Spring needed?  (springs probably offset solenoid force! it is unnecessary if load force can resets)
   If yes, Should it be A. Outside spring on plunger as on the color animated picture (prefered) or
   B. Iinside coil, between moving plunger & static iron core stop (hamper solenoid force)
   What spring force (troke) is needed when solenoid is on or/and off?
6. Any requiremens for connection of assembling & power supply?
7. Connections of Load: select plunger or pushing rod shape & specify dimensions.
