Choosing among industrial sensors and switches means deciding whether you need a switched contact, a continuous pressure signal, or long-range optical detection. The four listed-price options here range from $23.95 to $425, so the cost span is wide, but the bigger issue is matching the sensor type to the machine behavior.
Quick Take
If you need pressure sensing and want to spend the least, the Honeywell 89028 is the low-priced industrial pressure sensor. If you need a pressure switch for automation controls, the Honeywell MER02000BYPNKABN01 is the pressure switch in this group. If you need a transducer with a continuous output, the ifm efector PI1093 provides that output type, but at the top listed price. If your task is detecting a beam or object at distance rather than measuring pressure, the Photoelectric Switch 12mm 636V 020M covers a 0-20M range with NPN output.

Decision Matrix
| Listed Option | Best For | Watch Out |
|---|---|---|
| Honeywell MER02000BYPNKABN01 | Automated control systems that need a pressure switch | It is not a transducer |
| Honeywell 89028 4 | Budget-focused industrial pressure sensor | It is a sensor listing, not a switch or transducer |
| ifm efector PI1093 | Industrial setups that need a transducer | Highest listed price |
| Photoelectric Switch 12mm 636V 020M | Long-range photoelectric detection | Not for pressure monitoring |
Product Notes
Honeywell MER02000BYPNKABN01 Pressure Switch Industrial Sensor New
Because this is a pressure switch for industrial automation, it will not give you the same output behavior as the ifm efector transducer. The listing includes the box, and the model MER02000BYPNKABN01 appears as both the model and MPN. At a listed price of $49.99, it sits in the middle of this group. If your setup needs a switch action instead of a measured pressure value, this is the only pressure switch in the four options. The trade-off is that you trade away the transducer output detail you get with the ifm efector PI1093.
Honeywell 89028 4 Industrial Pressure Sensor 103716 8902842131 NEW
At $23.95, this Honeywell pressure sensor is the lowest-priced item in the set. The model is listed as 103716 and the MPN as 8902842131, which makes it a specific Honeywell part rather than a generic replacement. The title says pressure sensor, not pressure switch or transducer, so the listing is centered on a sensing part rather than on a switching contact or a transducer output. If you need to keep the first cost down and a basic industrial pressure sensor is all your project requires, this listed option gives you a Honeywell part with a modest price tag.
ifm efector PI1093 Pressure Sensor / Transducer Industrial Automation
The ifm efector PI1093 is the one listing in this group that spells out analog output and absolute pressure type. It also identifies DC current, so it is aimed at automation systems that need an analog absolute-pressure signal rather than a simple switching contact. The listed price is $425, making it the highest-priced item among the four. If your design requires an analog absolute-pressure transducer, this is the product that gives you that detail in the listing. The limitation is the large price step from the other options, so it should be chosen only when the analog-output requirement is real.
Photoelectric Switch 12mm 636V 020M Laser Sensor NPN Industrial Sensor
The Photoelectric Switch 12mm 636V 020M is a different sensing category: it is an NPN photoelectric sensor with a 0-20M range and 6-36V supply described in the listing. The E3F-20M-NO designation and normally open contact type point to beam/object detection. The listed price is $39.72, which sits near the middle of this list. It also carries IP66 construction for indoor/outdoor use, so it stands out for environments where photoelectric sensing is needed. The trade-off is clear: it is not a pressure device, so it won't solve a pressure monitoring problem. Use it when your task is detecting presence, position, or passage through a beam.
Final Recommendation by Use Case
- For a basic industrial pressure sensor with the lowest listed price in this set, look at the Honeywell 89028 4 Industrial Pressure Sensor.
- For a pressure switch aimed at industrial automation, choose the Honeywell MER02000BYPNKABN01.
- For an analog absolute-pressure transducer, the ifm efector PI1093 is the listed option that matches that need.
- For long-range photoelectric detection, the Photoelectric Switch 12mm 636V 020M is the one to use.
