M12 Class 1 Laser Emiꢂer
Datasheet
IEC Class 1 Laser for Use with Banner Modulated Receivers
•
•
•
•
•
A low-power device emiꢀng a visible red beam, 650 nm wavelength
Beam is bore-sighted to within 2 milliradians and 0.25 mm of the housing centerline
Collimated, apertured beam is 2 mm diameter with divergence of less than 1 milliradian
Compaꢁble with a variety of Banner modulated photoelectric receivers
Useful for medium-range sensing, or for sensing very small objects or profiles; excellent
mechanical repeatability in posiꢁon-sensing applicaꢁons

•
Smooth-barrel aluminum housing is suitable for a precision mount
Available with unterminated, 2 m (6.5 ꢂ) cable or 150 mm (6 in) quick-disconnect cable
Modulated beam (33 kHz, 25% duty cycle)
57 mm (2.25 in) long overall
10 V dc to 30 V dc operaꢁon
WARNING: Not To Be Used for Personnel Protecꢀon
Never use this device as a sensing device for personnel protecꢀon. Doing so could lead to serious injury or death.
This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety
applicaꢁons. A sensor failure or malfuncꢁon can cause either an energized or de-energized sensor output
condiꢁon.
CAUTION: Never stare directly into the sensor lens. Laser light can damage your eyes. Avoid placing any mirror-like
object in the beam. Never use a mirror as a retroreꢃecꢁve target.
CAUTION: Use of controls or adjustments or performance of procedures other than those specified herein may
result in hazardous radiaꢁon exposure. Do not aꢄempt to disassemble this sensor for repair. A defecꢁve unit must
be returned to the manufacturer.

Mounꢀng
Mounꢁng suggesꢁons:
•
To take advantage of the bore-sight beam placement offered by the M12 laser emiꢄer, use a two-part clamp mount or a
mounꢁng block with a precision-drilled hole. Allow minimum clearance for the 12.7 mm (0.50 in) diameter housing, maximum
diameter 12.83 mm (0.505 in).
•
Clamp on both sides of the label. Do not clamp only on the labeled area. Use only plasꢁc-ꢁpped screws or set screws – not
metal – to avoid compression of the housing.
Mounꢁng bracket assembly model SMB46X3 is recommended for use with the M12. The assembly includes:
1
To order the 9 m (30 ꢂ) PVC cable model, replace the suffix "Q" with "W/30" in the model number. For example, M126E1LDQ W/30.
Models with a quick disconnect require a maꢁng cordset.
