Choosing the right sensor for an industrial machine means matching the sensing technology to the job. Do you need to detect an object's presence, or do you need to monitor pressure? This head-to-head lines up a photoelectric switch designed for presence detection against a Honeywell industrial pressure sensor. With a $15.77 price gap between them, the two serve very different purposes. The better choice depends on what your application demands.
Quick Verdict
If presence detection is the task, the photoelectric switch is the clear pick. Its detection capability and switching output make it a natural fit for gates, counting, and positioning. If you need industrial pressure monitoring and want to keep your spending closer to the $24 end of the range, the Honeywell sensor is the one to buy.
Comparison Table
| Aspect | Photoelectric Switch | Honeywell Pressure Sensor |
|---|---|---|
| Price | $39.72 | $23.95 |
| Condition | New | New |
| Core Function | Photoelectric detection with NPN output | Industrial pressure sensing |
| Sensing / Outputs | 0-20M range, 6-36V, normally open, RCA connector | Model 103716, MPN 8902842131 |
| Best Use | Presence detection, counting, positioning | Pressure monitoring in industrial systems |
These two are not direct competitors; they solve different problems at different price points.
Where Each Product Wins
Photoelectric Switch wins for jobs that involve detecting moving objects, counting parts, sensing personnel passing through a gate, or positioning machinery. A through-beam setup can span a driveway or doorway, making it ideal for automatic doors, safety gates, and conveyor counting. This is the sensor to choose when a physical trigger isn't an option.
Honeywell Pressure Sensor wins when your real need is knowing the pressure in a hydraulic, pneumatic, or other industrial process. The Honeywell brand and part identification make it easy to source the right pressure sensor for replacement or new installation. If you already work with Honeywell pressure sensors, this is a direct way to add a spare.
Product Notes
Photoelectric Switch 12mm 636V 020M Laser Sensor NPN
This is the sensor to choose when you need distance detection for automation tasks. The 0-20M sensing range covers large openings and lets you mount the sensor across a driveway, doorway, or conveyor gap. The 6-36V power input gives you flexibility with common industrial supplies, and the NPN output with a normally open contact gives you a clear switching signal for many PLCs and controllers. If your control system expects PNP inputs, you would need an interface adapter, so check that before you order. The stainless steel contact material adds durability to the RCA connector assembly, and the 12mm body suits tight mounting spots. At $39.72, it costs noticeably more than the Honeywell, but the detection range and the ability to sense through a beam are what justify the higher price.
Honeywell 89028 4 Industrial Pressure Sensor 103716
This sensor gives you a lower-priced path into industrial pressure sensing at $23.95. The title carries the Honeywell brand, model 103716, and MPN 8902842131, which tell a buyer who knows Honeywell sensors exactly what this part is. The condition is new, and the application is industrial, so it's aimed at plant, hydraulic, or pneumatic systems. The main decision point is whether the 103716 model matches the pressure range your system requires, because that compatibility is the core of this product's identity. The sensor doesn't include any of the detection features found on the photoelectric switch, so it's strictly for pressure-sensing roles. For buyers who already have the pressure specifications, this is a straightforward way to keep costs down while getting a Honeywell-branded sensor.
Final Choice by Use Case
Final choice by use case: Choose the Photoelectric Switch when you need to detect movement, count parts, or sense passing objects over long distances. Choose the Honeywell Pressure Sensor when you're monitoring pressure in an industrial process and want the lower-priced option. Consider the mounting space, output requirements, and whether you need detection or pressure measurement; those factors point to one sensor more than the other. There is no wrong buy here-just the wrong tool for the wrong job.
