Features
| Common to RCS DC series electric
motor driven actuators RCS DCR series actuators are powered by
custom DC motors specifically designed to prevent gear breakage
found in actuators using standard DC motors.
| Precision cut gears and shafts
are heat treated, high alloy steel.
| Gear train will withstand stall
torque.
| Unique adjustment plates permit
fast, accurate setting of travel limit switches.
| Switch activating cams are
independently adjustable for maximum setting flexibility and
accuracy.
| Mechanical, visual position
indicators.
| Built-in motor overload signal
most models.
| Permanent lubrication.
| Operates in any position.
| Accessible, clearly marked
integral terminal strip assures fast, easy wiring.
| Output for output, the most
compact and versatile actuators in the industry.
| Electroless nickel plated output
shafts provide maximum corrosion protection.
| Suited for automated and computer controlled systems. |
| | | | | | | | | | | |
Optional Features
| DC current limited to control output torque.
| Custom designs for varying computer control systems.
| Duty cycle: 50% standard.
| Integral potentiometer. 1,000 to 15,000 Ohms, 2 Watts, 1%
linearity; other resistances available.
| Auxiliary function switches.
| Relays for two-wire control.
| Special shah configurations.
| Heaters and thermostats.
| Special corrosion-resistant coatings.
