Servomech® CLA and CLB actuators with integrated limit switches
Linear actuators for medium-sized applications, integrated limit switches and potentiometers
The CLA (A = ACME = acme screw) and CLB (B = ball screw) series offer the convenience of built-in rotary switches mounted under an IP65 cover.
The switches are used for end position indication and can be easily adjusted. It is possible to add a third switch for intermediate positions or a potentiometer for an analog signal for positioning.
As standard, the switches with 250 VAC 21 A and 30 VDC 14 A are used to switch off the motor externally. Optionally, drives can be supplied with DC motors where the limit switches are wired directly to the motor.
Available motors are DC (24 V standard, 12 & 36 V optional) or AC (1-phase or 3-phase).
Type CLA has a trapezoidal spindle (ACME thread) and a maximum duty cycle of 15 % (DC motor) or 30 % (AC motor).
The CLB type uses a ball screw for higher efficiency and a duty cycle of up to 100 %. The motors are usually equipped with brakes.
