•
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 applicaꢀons
Current sourcing (PNP), current sinking (NPN), or bipolar (one NPN and one PNP)
output, depending on model

Fast 500-microsecond response ꢀme
10 V dc to 30 V dc supply voltage
Single-turn potenꢀometer sensiꢀvity adjustment
Visible red beam
Selectable Light Operate (L.O.) or Dark Operate (D.O.) with sealed switch
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
applicaꢀons. A sensor failure or malfuncꢀon can cause either an energized or de-energized sensor output
condiꢀon.

Integral 3-pin M8/Pico-style quick disconnect models are listed. Models with a quick disconnect require a maꢀng cordset.
Integral 2 m (6.5 ꢁ) unterminated cable models are listed.

•
To order the 9 m (30 ꢁ) 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.
