KALEN AUTOMATION

Through-Beam Photoelectric Sensors

KALEN Automation offers through-beam photoelectric sensors in cylindrical, rectangular and compact housing styles for industrial object detection. Each arrangement uses a separate emitter (transmitter) and receiver facing each other across the detection path. Choose a housing pair that fits the available mounting space on both sides of your machine and allows access for alignment and cleaning. We can review different sensing distances, NPN / PNP receiver outputs, NO / NC switching, 3-wire / 4-wire receiver configurations, cable or connector connections and DC supply requirements. Available combinations depend on the selected model; emitter and receiver wiring must be confirmed separately. For conveyor detection, packaging machinery, object presence checks, counting or positioning, share the target dimensions, line speed, spacing and emitter-to-receiver distance. OEM/ODM enquiries are welcome for machine builders and distributors. Send your product photo or reference model, required specifications and quantity so we can recommend a suitable matched pair. Mounting accessories and supply scope are confirmed in the quotation.

Applications

Conveyor detection

Discuss detection of products passing between an emitter and receiver. Provide belt speed, object spacing and mounting positions on both sides.

Packaging machinery

Review package or component detection at a machine station. Share target dimensions, surface characteristics and any transparent objects for suitability checks.

Object presence detection

Provide the smallest target and its travel path. Confirm the required beam arrangement and mounting clearance for the selected model.

Counting

Specify object spacing and line speed. Ask us to confirm response time and receiver output compatibility with your counter or PLC.

Positioning

Share the required switching position and repeatability. Review alignment and mounting stability, then confirm performance against the exact model.

Available Options

Sensing distance & alignment

Provide the emitter-to-receiver distance and both mounting positions. Confirm the rated range, alignment requirements and target suitability.

NPN / PNP receiver output

Specify the output required by your PLC or controller. Confirm receiver output availability and its wiring diagram; the emitter has a separate connection.

NO / NC switching

Tell us whether normally open (NO) or normally closed (NC) operation is required. Confirm the receiver’s light-on/dark-on behavior for your application.

3-wire / 4-wire

Share the required receiver wire configuration. Available combinations depend on the model; confirm emitter and receiver wiring separately.

Cable / connector

Request cable or connector connections and provide cable lengths or connector details for both units. Confirm availability before ordering.

DC supply voltage

Provide your required DC voltage. Confirm the rated operating voltage and electrical limits of both emitter and receiver.

Confirm the matched emitter and receiver models, sensing distance, target suitability, dimensions and separate wiring diagrams before ordering. Illustrated lens colors do not specify the emitted wavelength. Included mounting accessories are confirmed in the quotation.

Need help selecting a sensor?

Please send us your required sensing distance, output type, voltage, wiring, quantity and product photo/reference model. We will recommend a suitable model. Please also include the emitter and receiver mounting positions and target dimensions.
