Datasheet

• An easy-to-use, self-contained, opposed-mode sensor pair in a U-shaped housing

• Rugged, sealed, die-cast metal housing is rated IEC IP67 (NEMA 6)

• Easy and economical to mount; molded-in beam guides simplify beam placement

• Eight slot widths from 10 mm to 220 mm for a wide variety of sensing applications

• Current sourcing (PNP), current sinking (NPN), or bipolar (one NPN and one PNP)

output, depending on model

• Fast 500-microsecond response time

• 10 V dc to 30 V dc supply voltage

• Single-turn potentiometer sensitivity adjustment

• Visible red beam

• Selectable Light Operate (L.O.) or Dark Operate (D.O.) with sealed switch

WARNING: Not To Be Used for Personnel Protection

Never use this device as a sensing device for personnel protection. 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

applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output

condition.

1 Integral 3-pin M8/Pico-style quick disconnect models are listed. Models with a quick disconnect require a mating cordset.

2 Integral 2 m (6.5 ft) unterminated cable models are listed.

•

To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, SLM10B6 W/30.

•

To order the 150 mm (6 in) PUR cable model with a 4-pin M12/Euro-style quick disconnect, add the suffix "QPMA" to the model number. For

example, SLM10B6QPMA.
