M12 Class 1 Laser Emitter

IEC Class 1 Laser for use with Banner modulated receivers

Printed in USA 10/03 P/N 53808 rev. B

• A low-power device emitting 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 2mm diameter with divergence of less than 1 milliradian.

• Compatible with a variety of Banner modulated photoelectric receivers (see Excess Gain

chart, page 3).

• Useful for medium-range sensing, or for sensing very small objects or profiles; excellent

mechanical repeatability in position-sensing applications.

• Smooth-barrel aluminum housing is suitable for a precision mount.

• Available with unterminated, 2 m (6.5') cable or 150 mm (6") pigtail, quick-disconnect

cable

• Modulated beam (33kHz, 25% duty cycle)

• 57 mm (2.25") long overall

• 10 to 30V dc operation

*9 m (30') cables are available by adding suffix “W/30” to the model number to the cabled version (e.g., M126E1LD W/30).

A model with a QD connector requires an accessory mating cable. See page 6.

Features and Benefits

CAUTION . . .

Never stare directly into

the emitter lens. Laser

light can damage your eyes.

Avoid placing any mirror-like object in

the beam. Never use a mirror as a

target. (See Figure 5.)

WARNING . . . Not To Be Used for Personnel Protection

Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.

These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety

applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current

Banner Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

M12 Class 1 Laser Emitter Mounting Mounting suggestions: • To take advantage of the bore-sight beam placement offered by the M12 laser emitter, use a two-part clamp mount or a mounting block with a precision-drilled hole. Allow minimum clearance for the 12.7 mm (0.50") diameter housing, max. dia. 12.83 mm (0.505"). • Clamp on both sides of the label. Do not clamp only on the labeled area. Use only plastic-tipped screws or set screws – not metal – to avoid compression of the housing.

M12 Class 1 Laser Emitter Alignment Approx. 2 mm Approx. 0.5mrad = 0.029º Laser Emitter Sensing Distance = X W Conventional modulated infrared LED photoelectric emitters are designed with beam divergence angles of several degrees. As a result, most emitters are easily aligned to their receivers by simple line-of-sight methods. W = 2 mm + 2X(tan.0029º) = 2 mm + X(0.001) Opposed Distance (X) In sharp contrast to conventional photoelectric emitters, M12 laser emitters have a beam divergence of only 0.
