Stepping Up Intelligence on Linear Actuators

Cleveland, OH - October 13, 2009


Leading linear motion systems manufacturer, Nook Industries (Cleveland, OH), has introduced its Series 500 programmable linear actuator that offers an expanded range of performance. This new actuator generates higher force, has longer life, increased duty cycles, higher speed and programmability. Developed by Nook's Precision Actuator Group, the series 500 actuator offers versatility, precision and control for a broad range of applications (including military, packaging and automotive).

Linear Position Sensor:

Notably, the new Series 500 offers an optional internal Linear Position Sensor (LPS) that provides intelligent, programmable positioning and verification feedback for both parallel and higher speed in-line configurations. Load capacities range up to 1,000 lbs. for both in-line (See Image 1 in Figure 1 Below) and parallel (See Image 2 in Figure 1 Below) configurations and stroke lengths range from 2"-to-24" (with custom lengths available upon request).

The Series 500 actuator can be supplied as a complete system (including motor, drive and controller). Ball screw driven designs are available for continuous high-speed, high duty-cycle applications and can operate at speeds of up to 25 inches per second. Acme screw driven designs are available for low duty cycle and where self-locking is desired.

Nook's Series 500 is also designed with T-Slot extrusions to accommodate adjustable limit switches and the optional external Linear Position Sensor. The LPS is a non-contact/no-wear sensor with a small package size that requires a short operating space. The LPS requires half the space when compared to LVDTs or rod and cylinder pots. Fitting where no other sensors typically can, it still offers all the benefits of magnetostrictive sensing.

According to Nook Industries' CEO, Christopher Nook, "the Series 500 linear actuator helps to fill a gap in the market by offering the LPS option. The LPS provides defined linear position for advanced accuracy and programmable control. We'll also be offering his type of option on our new line of ball screw actuators and roller screw actuators."

Additional LPS benefits include:

  • Easy Interfacing: Choice of analog or self-interrogating PWM signals.
  • Low Power Requirements: Allows use of printed circuit-level supplies of +5 Vdc.
  • Optional Supply Voltages: Allows use in +12 Vdc Systems.
  • Customizable Reading Direction: Forward or reverse acting analog output allows match to control requirements.

Control Specifications / Options:

Nook's Series 500 actuator offers the following controls complete with I/O, indexer and drive:

Stepper Controller: Capable of full, half-step or micro-stepping. 10 foot power cable included.

Servo Controller: Servo controller and Amplifier supplied in one package. 10 foot power and feedback cables included.

Comprehensive options are also available for the following: mounting styles, rod ends, brakes, protective bellows, stroke lengths, various motor mounting configurations and linear encoder contained inside the actuator.

Nook's Series 500 actuator also meets the IP65 (Ingress Protection) environmental rating for products which can guarantee resistance against dust and water.
