Overview
The SLM Series Slot Sensor (sometimes called a “fork sensor”) comprises an opposed-mode emitter and its receiver inside a single convenient housing.
Opposed-mode sensing is very reliable, and the single, self-contained housing provides easy installation, with no sensor alignment required. In addition, molded-in arrows on the housing show at a glance the position of the beam, simplifying installation placement. Applications include counting, gear tooth detection, edge detection, part sensing on conveyor rails and belts, position and orientation verification, dimension verification, tool break monitoring, and level monitoring.

• 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
