Electric Stopper Cylinders
LEB electric stopper cylinders can provide a simpler conveyor stop solution than pneumatic equivalents. Control options include either with a programmable controller, or controllerless with simple 24VDC on / off operation. Transferred object weights can vary from 25 to 800 kg with a range of actuator sizes and strokes available.
LEBH-X3 Electric Stopper Cylinder, Controllerless
The LEBH is an electrically powered stopper cylinder for managing package movement on a conveyor. The LEBH does not require a controller, so it can be operated with a simple ON or OFF voltage signal. Packages are stopped by its roller lever, while a hydraulic shock absorber cushions the kinetic energy. This actuator is extended by spring force and retracted by the electric motor. Once retracted, a solenoid holds the retracted position with the motor off. This is the largest of the LEB stoppers, for stopping transferred objects weighing up to 800 lb / 1760 kg. The LEBH is interchangeable with SMC's RS2H pneumatic stoppers, for conveying systems converting to electric from compressed air.
- Sizes: 50, 63, 80
- Strokes, mm: 30 (sizes 50, 63); 40 (size 80)
- Rod end: Roller lever with built-in shock absorber
- Rod Travel: Single acting retract with spring extend
- Actuation: DC motor with belt-driven ballscrew
- Power requirement: 24 VDC ±10%
LEBQ-X31 Electric Stopper Cylinder, Controllerless
The LEBQ-X31 is an electrically powered stopper cylinder for managing package movement on a conveyor. The LEBQ-X31 does not require a controller, so it can be operated with a simple ON or OFF voltage signal. Packages are stopped by its roller lever, while a hydraulic shock absorber cushions the kinetic energy. This actuator is extended by spring force and retracted by the electric motor. Once retracted, a solenoid holds the retracted position with the motor off. This is an intermediate stopper in the LEB family, for stopping transferred objects weighing up to 70 kg / 154 lb. The LEBQ-X31 is interchangeable with SMC's RSQ pneumatic stoppers, for conveying systems converting to electric from compressed air.
- Size: 40
- Stroke: 20mm
- Rod end: Roller lever with built-in shock absorber
- Rod Travel: Single acting retract with spring extend
- Actuation: DC motor with belt-driven ballscrew
- Power requirement: 24 VDC ±10%
LEBQ-X1 Electric Stopper Cylinder, Controller Type
The LEBQ-X1 is an electrically powered stopper cylinder for managing package movement on a conveyor. The LEBQ-X1 motor requires a controller for operation, either JXC (step data) or LECPA (pulse input) series. The rod is extended and retracted by a slide screw with cam mechanism. Several rod end options are available. This is the small to intermediate stopper in the LEB family, for stopping transferred objects weighing up to 130 kg / 286 lb. The LEBQ-X1 is interchangeable with SMC's RSQ pneumatic stoppers, for conveying systems converting to electric from compressed air.
- Sizes: 32, 50
- Stroke, mm: 20 (size 32); 30 (size 50)
- Rod end options: Chamfered rod, rod with roller, roller lever with built-in shock absorber
- Rod Travel: Slide screw with cam
- Motor: 24 VDC step motor
