- Third-party PLCs (Allen-Bradley, Mitsubishi, Omron, Beckhoff) — Compatible with any 24 VDC PNP digital input
- Safety PLCs — Not rated for SIL/PLd safety functions; use SIEMENS 3SE / 3SF series for safety applications
Selection Guide
Use the following criteria to confirm the 3RG4014-4AB02 is the right choice, or to identify a suitable alternative:
- Sensing Distance: Required ≤ 4 mm nominal → 3RG4014-4AB02 ✓ | Need > 4 mm → consider 3RG4024 (8 mm) or 3RG4034 (15 mm)
- Output Logic: PNP NO required → 3RG4014-4AB02 ✓ | NPN or NC needed → select -4AA02 (NPN NO) or -4AB01 variants
- Housing Size: M14 cylindrical → 3RG4014-4AB02 ✓ | M12 needed → 3RG4012 series | M18 needed → 3RG4018 series
- Supply Voltage: 10–30 VDC system → 3RG4014-4AB02 ✓ | AC supply → select 3RG46 AC series
- Environment: IP67 standard → 3RG4014-4AB02 ✓ | Weld-field immune needed → 3RG4614 series
- Safety Function: SIL/PLd required → use SIEMENS 3SE/3SF safety switches instead

Replacement & Compatibility FAQ
Q: Can I use a 3RG4014-4AB03 to replace a 3RG4014-4AB02?
A: Yes, the -4AB03 is a newer revision of the same series and is a direct drop-in replacement in most applications. Verify the datasheet for any minor specification changes.
Q: Is the 3RG4014-4AB02 compatible with Allen-Bradley PLCs?
A: Yes. Any PLC with a 24 VDC PNP digital input can accept the signal from this sensor. No special configuration is required.
Q: What is the difference between PNP and NPN output?
A: PNP (sourcing) outputs a positive voltage signal when active; NPN (sinking) pulls the signal to ground. Match the output type to your PLC input card specification.
Q: Can this sensor detect non-metallic objects?
A: No. Inductive proximity switches detect ferrous and non-ferrous metals only. For plastic, wood, or liquid detection, use a capacitive proximity switch.
Q: Do you provide a warranty?
A: Yes. All genuine SIEMENS parts sold through Konmask.com carry the manufacturer’s standard warranty. Contact us for details.
