Metal Slot Sensors feature response time of 500 µsec.

Press Release Summary:

SLM Series sensors, available in 6 fixed slot widths from 10-220 mm, provide opposed-mode sensing of objects as small as 0.30 mm that pass between emitter and receiver. Along with U-shaped metal housing, they include single-turn potentiometer sensitivity adjustment and visible red beam. Sensors, installed using molded-in beam guides, operate on 10-30 Vdc and are offered with current sourcing (PNP), current sinking (NPN), or bipolar (one NPN and one PNP) output.

Original Press Release:

Rugged Metal Fixed-Distance Slot Sensors Deliver Ultra-Fast Resonse Time.

Minneapolis, MN-March 25, 2006-Banner Engineering Corp. announces its SLM Series Metal Slot Sensors that sense objects that pass between its fixed-distance opposed-mode emitter and receiver. Available in six slot widths, all models have a rugged metal housing and a fast response time of 500 microseconds, making them ideal for high-speed counting, edge detecting, position verifying and level monitoring applications. The fixed slot width provides reliable opposed-mode sensing of objects as small as 0.30 mm. The available slot widths of 10, 30, 50, 80, 120 and 220 mm range from $119 to $139.

"The U-shaped metal housing of the SLM sensor makes it versatile, durable and easy to use," explained Jeff Curtis, senior application engineer for Banner Engineering. "There's no need to align opposed-mode emitter and receivers. The SLM emitter and receiver are in fixed arms of the housing. You just install it, using the molded-in beam guides and integral mounting holes." Curtis adds, "The SLM is available in a range of sizes, making it an ideal alternative to existing fiber and difficult to mount opposed-mode sensors.

Applications. The SLM Series sensors enable users to accurately detect small objects at incredibly fast throughput speeds. The SLM Series sensors are ideal for a wide range of applications in the printing, pharmaceutical, packaging, material handling and automotive industries. Examples include the following:

Sense parts on conveyor rails and belts.
Detect object edges or protruding features.
Verify position, orientation and dimensions of components.
Monitor container fill levels.
Count gear teeth.

Several features of the SLM Series sensor makes it easy to use:
Available in six slot widths from 10 to 220 mm for easy installation
Delivers a fast response time of 500 microseconds
Includes single-turn potentiometer sensitivity adjustment and visible red beam
Installs easily using molded-in beam guides that simplify beam placement
Offers light or dark operate, using a sealed switch
Features sealed, die-cast metal housing rated IEC IP67, NEMA 6
Includes 2 m or 9 m attached cable, 4-pin Euro-style QD or 3-pin Pico-style QD

Specifications. SLM Series sensors operate on 10 to 30V dc and are available with current sourcing (PNP), current sinking (NPN), or bipolar (one NPN and one PNP) output, depending on the model. Bicolor indicator lights provide ongoing operating status of the sensor.
