Define what the sensor must detect
Optical principle, target characteristics and electrical interface determine whether a sensor fits the application. A similar housing does not establish equivalent behavior.
- 01
Match the sensing principle
Identify the actual detection task and the optical principle stated for the exact sensor model.
- Target and background
- Optical principle
- Required sensing range
- 02
Check the electrical interface
Compare supply, output type, connector or cable and any communication interface.
- Supply voltage
- Switching output
- Connector pin assignment
- 03
Review mounting and target conditions
Check available mounting space, target material and the effect of surrounding surfaces.
- Mounting geometry
- Target characteristics
- Background conditions

Planning a replacement
Capture the installed model and application context before selecting replacement equipment.
- 01
Record the full sensor model, output type and connection details.
- 02
Document the sensing distance, target and mounting arrangement.
- 03
Check the exact model datasheet before replacing a sensor with a similar housing.
Sensors and detection questions
Practical checks for identifying, selecting and replacing controller hardware.
Are standard photoelectric sensors suitable as safety switches?
A standard detection sensor must not be treated as a safety device. Use equipment specified for the required safety function and the engineered safety system.
