Product Overview

Banner Engineering S18AW3FF25Q1 is an EZ-BEAM S18 Series fixed-field photoelectric sensor with background suppression. It detects objects at a defined 25mm range using infrared light and rejects anything beyond that distance, eliminating false triggers from reflective backgrounds or downstream objects. The M18 cylindrical barrel mounts in standard 18mm sensor brackets. Output is an SPST solid-state AC switch, light-operate, rated for 20-250V AC systems. Connection is via an integral 4-pin 1/2-inch Micro quick disconnect. IP67 and IP69K rated for washdown environments.

Key Features

• Sensing mode: Fixed-field with background suppression
• Sensing range: 25mm
• Input voltage: 20-250V AC
• Output: SPST solid-state AC switch, light-operate
• Connection: 4-pin 1/2-inch Micro integral quick disconnect (QD)
• Housing: M18 cylindrical barrel
• Environmental rating: IP67 and IP69K - washdown rated
• Operating temperature: -40°C to 70°C
• 100ms power-up delay before output conducts
• Also known as Banner 58063

Applications

• Maintenance technician swapping a failed presence sensor on a conveyor line - drop-in replacement without rewiring when existing cordset uses a 4-pin Micro QD
• Machine builder integrating precise part-positioning detection into a packaging or assembly cell where background clutter would cause false reads on a standard diffuse sensor
• System integrator specifying a washdown-rated sensor for a food or beverage processing line where IP69K compliance is a hard requirement
• Automation engineer retrofitting legacy AC-controlled machinery that cannot accept a DC output sensor
• Maker or hobbyist building an AC-powered proximity trigger for a custom fixture, gate, or display - solid-state switching with no moving parts

Frequently Asked Questions

Does this sensor work with DC power supplies?

No. The S18AW3FF25Q1 requires 20-250V AC. It is not compatible with DC voltage power supplies.

What cordset do I need to connect this sensor?

A mating 4-pin 1/2-inch Micro QD cordset is required. The sensor has an integral quick-disconnect base - no cordset is included with this unit.

Is this rated for washdown environments?

Yes. IP67 and IP69K rated. Suitable for high-pressure washdown applications.

What is the difference between this model and the S18AW3FF25 (no Q1)?

The S18AW3FF25 uses an integral 2-meter cable. The S18AW3FF25Q1 uses a 4-pin Micro quick-disconnect connector instead - same sensing performance, different connection method.

Is this sensor suitable for safety or personnel protection applications?

No. Not rated or approved for personnel safety applications. Use a dedicated safety-rated sensor for those requirements.

Background suppression sounds like a spec-sheet detail until you have spent an afternoon chasing phantom triggers on a shiny conveyor. This sensor was built to end that problem at exactly 25mm - hand it off to the machine and let it do the one thing it does without complaint.
