30 mm Slot Detection
E3S-GS30 Slot Photoelectric Sensor
A compact groove-type photoelectric switch for repeatable detection when labels, sheets, tabs, carriers or small parts pass through a fixed 30 mm slot. The integrated emitter and receiver help simplify installation and reduce alignment drift.
30 mm slot | 12-24 VDC | Groove type
Stable Detection for Guided Moving Targets
The E3S-GS30 is useful when the target path is controlled and the object can pass through the sensor groove. Because the light path is fixed inside the body, the machine builder does not need to mount and align a separate transmitter and receiver.
- 30 mm groove supports labels, sheets, tabs, carriers and small parts
- Integrated optical path helps reduce alignment and maintenance work
- Good for counting, edge detection and position confirmation
- Compact body fits feeding machines, packaging equipment and guide mechanisms
Designed for Repeatable Pass-Through Detection
Emitter and Receiver in One Body
The fixed optical structure reduces separate mounting work and helps keep detection stable over time.
Clean Interruption Signal
When the object enters the groove, it interrupts the beam at a predictable point for counting or position logic.
Practical for Compact Equipment
Suitable for machine areas where a small sensor body, simple bracket and short sensing path are preferred.

Where the E3S-GS30 Works Well
Use this model when the target path is guided and the object can pass through a fixed 30 mm slot.
Label Position Detection
Detect label edges, tabs or small flags passing through a consistent groove path.
Sheet and Film Feeders
Confirm thin material movement in feeders, dispensers and packaging machines.
Small Part Counting
Count opaque parts moving through a chute, rail or compact transfer mechanism.
Position Confirmation
Verify a carrier, plate or workpiece has passed the required point before the next machine action.
Before Choosing This Sensor
The target should pass cleanly through the groove and block the internal beam. Confirm target thickness, path variation, speed and vibration before fixing the bracket.
Confirm the electrical output
Different machines may require different output logic. Confirm NPN or PNP, normally open or normally closed, cable length and connector style before ordering.
- Target material, size, thickness and moving speed
- Available mounting space and target path direction
- PLC input type and required output logic
- Quantity, cable, connector, label and packaging requirements
Product Questions
Frequently Asked Questions
Is the E3S-GS30 a reflective sensor?
No. It is a slot/groove photoelectric sensor. The target is detected when it passes through the groove and interrupts the internal beam.
What targets are suitable?
Opaque labels, sheets, tabs, carriers and small parts are suitable when they pass through the slot and block the light path reliably.
Can it connect to a PLC?
Yes. Confirm the controller input type and required output logic before wiring the sensor into the machine circuit.
Can XSZ support OEM requirements?
Yes. Send the quantity, cable length, connector, label and packaging requirements for factory evaluation.
Need Pricing or an E3S-GS30 Sample?
Send the target size, slot path, PLC input type and order quantity. XSZ will confirm the configuration before quotation.
