SLM Series Slot Sensors
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.
• Models with a quick disconnect require a mating cordset.
