LS Linear Heads - Rack and Pinion Systems
Linear Heads

A "linear head" can generate linear motion simply by combining a standard AC motor. Linear heads can be combined with a wide range of standard AC motors and are also available with many different stroke lengths for use in simple operation such as push, pull, lift and lower.


High Thrust Force and Large Transportable Mass

The maximum transportable mass is approximately 1.5 times that of a conventional product. (The specific value varies depending on the basic rack speed.)

  • 220 lb. (100 kg) (4LS type)
  • 66 lb. (30 kg) (2LS type)

Many Stroke Variations

Select the stroke that best suits your specific application

  • 3.94 ~ 39.37 in. (100 ~ 1000 mm): 10 types (4LS type)
  • 3.94 ~ 31.50 in. (100 ~ 800 mm): 8 types (2LS type)

Easy to Achieve Reciprocating Operation

Use the dedicated photomicro sensor set (sold separately) and the limit switches (sold separately) to implement reciprocating motion or immediate stops with ease.

Reciprocating Operation

Flexible Mounting

Each model comes in two types - horizontal and vertical - to allow for mounting in different directions to meet various limitations or installation. Choose the type that best suits your system.

Mounting Direction

Two Installation Directions

Two mounting surfaces are provided. Choose the installation direction that best suits your system.

Installation


Limit Switch (sold separately)

With the limit switches, reciprocating operation can be performed easily. Each set consists of two limit switches, four dogs, limit switch mounting bracket and cover.

Limit Switch


PARP-MS

  • Special Dog Shape - The special dog shape allows signals to be output separately at two moving ends, or at a moving end and an intermediate stop position. Accordingly, control can be implemented easily using the minimum number of limit switches.
  • Easy Position Setting Using Dedicated Limit Switches and Dogs - Since the roller of the limit switch can travel over the dog, multiple point stop operation can be designed by increasing the number of dogs.

Photomicro Sensor (sold separately)

This sensor is used to implement reciprocating motion, return to home operation and detect the position of the rack. By installing a sensor on both sides of the rack, it is possible to detect two signals separately.

Photomicro Sensor


PARP-PS2 (for use with 2LS type) and PARP-PS4 (for use with 4LS type)

  • Compact Size - The photomicro sensor is compact which meets space-saving needs. This makes it possible to decrease dead stroke.
  • Suitable to Ensure Position Detection Repeatability - Ideally suited for position detection repeatability in the case of detecting the shielding plate from the same direction.
  • Two Line Output is Possible - By installing the sensors on both sides of the rack, it is possible to detect separately not only signals of both moving ends, but also signals of moving ends and an intermediate stop position.

RoHS Compliant

RoHS (Restriction of Hazardous Substances) Directive:
Directive on restriction of the use of certain hazardous substances in electrical and electronic equipment (2002/95/EC).
The RoHS Directive prohibits the use of six chemical substances in electrical and electronic products sold in the EU member states. The six controlled substances are: lead, hexavalent chromium, cadmium, mercury and two specific brominated flame-retardants (PBB and PBDE).
