Class 1 Laser Sensor
Magnetek
’s LaserGuard Mini Collision Avoidance System contains a Class 1 laser with a 660 nm
wavelength. Although the laser is eye-safe, it is recommended that no one look directly into the laser. Do
not open the laser sensor enclosure. There are no serviceable parts inside.

System Description
Magnetek's LaserGuard Mini Collision Avoidance System measures the distance between the laser
sensor's lens and its companion retro-reflective target by means of pulse ranging technology. This allows
for very accurate measurements and energy efficiency. The laser used in the LaserGuard Mini system is
set to measure distances from 8 in. to 164 ft (0.2-50m). The laser has a visible red light beam, which
makes system alignment very easy. On the front and top of the laser are two LEDs, which indicate power
(balloon 1) and alignment (balloon 2). A steady green light indicates power to the laser. In the event of a
laser short circuit, the green LED will flash at 4Hz. A yellow light indicates the target is acquired and
reading a signal.
