LA3-12V-5-A-SP-100 DC Linear Actuators feature built-in limit switches.

Press Release Summary:

LA3-12V-5-A-SP-100 DC Linear Actuators are designed with steel drive pinion and IP65 ingress protection. Units come in 8.5 L x 1.65 W x 3.25 in. D dimensions. Having stroke length of 100 mm, output force of 45 lb and gear ratio of 5:1, actuators deliver a F.L stroke speed of 2 in. per second and static load of 517 lb. Operated in -15°F to +150°F temperature range, units feature zinc alloy housing and aluminum outer tube.

Original Press Release:

12 Volt DC Linear Actuator with 67% More Output Force…

New 12V DC Linear Actuator widely applied in 4x4 Vehicle and Sport Truck Slide Steps now available from Stock in Minnesota, USA”

Midwest Motion Products of Howard Lake, Minnesota, is pleased to announce the release of a new DC Linear Actuator, the Model # MMP LA3-12V-5-A-SP-100. The Actuator accepts any 12V DC Input, including automotive battery power, and features a compact, lightweight design, measuring just 8.5” Long (fully retracted) by 1.65” wide and 3.25” tall. Mounting is accomplished with 0.25” diameter through holes on the rear end of the actuator and near the end of the extending cylinder.

This rugged and reliable Linear Actuator has been designed with a steel drive pinion, instead of the ‘usual’ plastic pinion, thereby allowing for 67% greater output force capacity than our Standard Actuators, without sacrificing stroke speed.
