*

Forces shown are without return spring. Forces shown <  > are with return spring. Forces shown in [ ] are in kilograms.

**

To determine the operating current, divide the power (watts) indicated in the above table by the applied voltage.
Solenoids will operate at any stroke less than maximum.

Note 1. Typical operating temperature for single 15 second operation of the energize coil is less than:

140°F(60°C) ± 10°F (6°C) for 1 in. (25 mm) Stroke Solenoids (70°F/21°C Rise above ambient)
120°F(49°C) ± 10°F (6°C) 1-1/2 in. (38 mm) Stroke Solenoids (50°F/10°C Rise above ambient)
See CAUTION statement on next page and note maximum housing temperature is 185°F (85°C).

Note 2. The energize-coil should not be activated for more than 15 seconds.

Longer energize-coil activation times will damage the solenoid.

Note 3. Allow minimum 15 minutes for cooling between activations of energize-coil to avoid damaging the 

solenoid. (Depends on length of time energize coil is energized.)

Note 4. The energize-coil must fully seat the plunger to allow the hold-coil to function properly.
