The type CLA & CLB actuators offer the convenience of built in rotary limit switches fitted under an IP65 cover.  The switches are used for end of stroke signals and can be easily adjusted.  There are options to add a third switch for intermediate positions or a 5k 0hm rotary pentiometer to give an analogue signal for positioning.


As standard the switches rated at 250VAC 21A and 30VDC 14A are used to externally switch off the motor.  Optionally actuators with DC motors can be supplied with the limit switches directly wired to the motor.


Available motors are DC (24V standard, 12 & 36V optional) or AC (1-phase or 3-phase).  Type CLA has an acme thread and maximum duty cycle of 15% (DC motor) or 30% (AC motor).  Type CLB used a ball screw for higher efficiency and duty cycles up to 100%.  Here motors are usually fitted with brakes.

ACTUATORS WITH BUILT-IN LIMIT SWITCHES

MEDIUM SIZE TYPES CLA & CLB TO 25000N

1 Also available are models CLA25S and CLA25M with similar performance but strokes up to 800mm.


2 Longer strokes to 1500mm possible by special modification.


Table values represent the maximum and minimum forces and speeds.  Other ratio codes with intermediate values are given in the catalogue.


CLB models with ball screw suit duties up to 100%.

CLB25 with AC motor - Linear speeds 2.5 to 58 mm/s, forces 1120-5000N, strokes to 400mm.

CLB27 with DC motor - Linear speeds 5 to 125mm/s, forces 410 to 5000N, strokes to 400mm.

CLB30 with AC motor - 3.5 to 60mm/s, 3300 to 9000N

CLB40 with AC motor - 2.5 to 56mm/s, 5400 to 12000N

CLB50 with AC motor - 4.2 to 47mm/s, 11800 to 25000N
