Slot / Groove Detection
E3S-GS30E4 30 mm Slot Photoelectric Sensor
Stable pass-through detection for labels, tabs, sheets, small parts and moving workpieces. The E3S-GS30E4 uses an integrated slot structure, so the emitter and receiver stay aligned inside one compact body.
30 mm slot | 12-24 VDC | Compact body
Reliable Detection Through a Fixed Groove
Unlike separate through-beam sensors, a slot photoelectric sensor keeps the light path fixed inside the U-shaped body. This helps reduce installation time and improves repeatability when the target passes through the groove at a known position.
- 30 mm groove supports sheet, label, tab and small-part detection
- Integrated emitter and receiver reduce alignment problems
- 12 to 24 VDC supply fits common control cabinets and machine systems
- Useful for feeding, counting, edge detection and position confirmation
Why Use a Slot Photoelectric Sensor?
No Separate Alignment
The transmitter and receiver are built into one body, helping avoid the alignment drift common with separate sensor pairs.
Clean Pass-Through Signal
When the target passes through the groove, it interrupts the optical path at a consistent point for counting or position detection.
Good for Tight Mechanisms
The compact groove design is suitable for feeders, labelers, guide rails and small automation equipment.

Where the E3S-GS30E4 Fits Best
Use this model when the target can pass through a fixed 30 mm groove and the machine needs a clean interruption signal.
Label and Tab Detection
Detect labels, tabs or small flags as they pass through a controlled groove path.
Sheet Edge Confirmation
Confirm the edge or position of paper, film, thin plastic sheets or similar materials.
Small Part Counting
Count small opaque parts moving through a chute, feeder or guide mechanism.
Feeding Machine Control
Verify material movement in feeders, dispensers and packaging equipment.
Before Choosing This Sensor
Slot sensors work best when the target enters the groove cleanly and blocks the beam. Check the target thickness, height, path variation and vibration before fixing the bracket.
Match the output to your controller
Before ordering, confirm the PLC input type, required NPN or PNP output, normally open or normally closed logic, cable length and connector style.
- Target size, thickness, material and moving speed
- Available groove space and mounting direction
- PLC input type and required output logic
- Quantity, cable, connector, label and packaging requirements
Product Questions
Frequently Asked Questions
Is the E3S-GS30E4 a reflective sensor?
No. It is a slot/groove photoelectric sensor. The object is detected when it passes through the slot and interrupts the internal light path.
What type of target is suitable?
Opaque labels, tabs, sheets, small parts and workpieces are suitable when they can pass through the groove and block the beam reliably.
Can it connect to a PLC?
Yes. Confirm the PLC input type and required output logic before wiring, especially NPN/PNP and normally open/normally closed requirements.
Can XSZ support OEM requirements?
Yes. Send the quantity, cable length, connector, label and packaging requirements so the factory can evaluate the configuration.
Need Pricing or an E3S-GS30E4 Sample?
Send the target size, groove space, PLC input type and order quantity. XSZ will confirm the configuration before quotation.
