Slot Type Sensor

Garantta Through-beam Slot Type Sensor, it is ultra-accurate, ultra-sensitive, ultra-reliable, and it can be designed into any production process. It eliminates the calibration issues and complexities of fiber optic sensors. Its ruggedness and built-in reliability make it suitable for demanding applications such as part position control, edge detection, fixture positioning, part ejection, pallet handling, automated pick and place, and error protection.

Garantta photoelectric slot sensor primarily consists of a light source, a receiver, and a detection slot. Its operating principle is to utilize a light emitter and a receiver, mounted face-to-face on opposite sides of a slot. When the emitter emits infrared or visible light, the receiver can receive this beam unless there are any obstructing objects. When an object enters the slot, the beam is blocked, reducing its intensity and causing a change in the receiver's output signal, enabling object detection and counting.

1. Stable detection without fear of external interference
2. The infrared strip beam design has strong resistance to foreign object obstruction. Reduce the probability of misoperation caused by dust and dirt coverage.
3. Good environmental resistance
4. Adopting special optical design, it can withstand environmental illumination up to 100kLx.
5. The protective structure reaches IP67, waterproof and dustproof.
6. Three installation methods to choose from
7. The Slot Type Sensor has reverse connection protection and load short circuit protection functions.

• Miniature design, small size, light weight, and easy installation, optimized for inspecting small parts.
• High switching frequency.
• The emitter and receiver are integrated, eliminating the need for alignment.
• Dedicated chip processing provides strong resistance to light and electromagnetic interference.
• High sensitivity, stable, and reliable in-slot inspection.

1. Appearance inspection
Casing: Check for cracks or damage.

Lens: Make sure the lens is clean and free of dirt.

Wiring: Check whether the wiring is firm, loose or broken.

2. Power supply check
Voltage: Confirm that the power supply voltage meets the specification requirements.

Polarity: Make sure the Slot Type Sensor of power supply polarity is correct.

3. Function test
No object blocking: When there is no object, the output signal should be normally open (NO) or normally closed (NC).

Object blocking: Block the light path and the output signal should switch states.

4. Sensitivity test
Response time: Block and remove the object to observe whether the response time meets the specifications.

Detection distance: Test whether the maximum and minimum detection distances meet the specifications.

5. Output signal check
Voltage/current: Use a multimeter to measure the output signal to ensure that it meets the specifications.

Stability: Test multiple times to ensure that the output signal is stable.

6. Comparison test
New vs. old: Compare with a new switch to check if the performance is consistent.

Brand comparison: Compare with switches of different brands to evaluate performance differences.

7. Troubleshooting
No output: Check power supply, wiring, and optical path.

Unstable output: Check lens cleanliness and environmental interference.

Slow response: Check Slot Type Sensor of sensitivity and response time settings.
