Compact Diffuse Reflective Detection
E3FA-DP12 Diffuse Photoelectric Sensor
Reliable direct object detection in a compact black ABS housing. The E3FA-DP12 combines a 300 mm sensing distance with NPN output and 10 to 30 VDC operation for industrial counting, positioning and presence checks.
Direct Detection Without a Reflector
The E3FA-DP12 receives light reflected directly from the target, so no separate reflector or receiver is required. Its compact form helps simplify installation beside conveyors, guides, fixtures and other tight machine assemblies.
- One-sided installation avoids reflector mounting and alignment
- 300 mm range supports common object detection tasks
- NPN output integrates with compatible sinking-input controls
- 10 to 30 VDC operation supports common industrial DC systems
Useful Detection Features for Compact Machinery
01 / DIRECT SENSINGNo Reflector Required
Detect objects directly and simplify installation where only one side of the sensing zone is accessible.
02 / USEFUL RANGE300 mm Detection
A practical working distance for packaging, assembly and material-handling machinery.
03 / NPN OUTPUTPLC Compatible
Use with a compatible sinking-input control circuit for clear object-present feedback.

Where the E3FA-DP12 Fits Best
Use this model when an object passes within 300 mm of the sensor and reflector-free direct sensing is preferred.
01
Conveyor Counting
Count cartons, trays and components as they move past a fixed sensing point.
02
Packaging Equipment
Confirm product presence before sealing, labeling and transfer steps.
03
Assembly Positioning
Verify that a part, carrier or fixture has reached the required machine position.
04
Material Handling
Detect bins and workpieces in compact transfer and sorting equipment.
Selection and Installation Checklist
Confirm the real target
Diffuse sensing distance changes with target color, surface finish, size and angle. Dark, glossy or angled objects may require a shorter operating distance.
Match the NPN input circuit
Check that the PLC or controller has a compatible sinking-input circuit before wiring the NPN output.

Product Questions
Frequently Asked Questions
01
Does the E3FA-DP12 need a reflector?
No. It is a diffuse reflective sensor and detects light returned directly from the target.
02
Can it connect to a PLC?
Yes. Its NPN output is intended for compatible sinking-input control circuits. Confirm the PLC input type and wiring diagram before installation.
03
Will every target be detected at 300 mm?
Actual sensing distance depends on target color, size, finish and angle. Use operating margin and test the actual target before fixing the installation.
04
Can XSZ support OEM orders?
Yes. Send the quantity, cable, labeling and packaging requirements for factory evaluation.
