For sensors, encoders, and machine-safety work, choosing between a Honeywell pressure switch and a Honeywell pressure sensor starts with one question: does your application need a discrete switching action or straightforward pressure sensing? That distinction separates the Honeywell MER02000BYPNKABN01 Pressure Switch from the Honeywell 89028 4 Industrial Pressure Sensor. Use this head-to-head to match the right Honeywell component to your project.
Quick Verdict
Go with the Honeywell MER02000BYPNKABN01 Pressure Switch when your project needs a defined switch for automation work. Go with the Honeywell 89028 4 Industrial Pressure Sensor when you want a straightforward industrial sensor. If your priority is a switch action in an industrial setting, the MER02000BYPNKABN01 is the one to choose; if sensor-first, the 89028 4 fits better.
Side-by-Side Comparison
| Product | Listed Price | Price Bar | Condition | Model / MPN | Type / Application |
|---|---|---|---|---|---|
| Honeywell MER02000BYPNKABN01 Pressure Switch | USD 49.99 | New - Open box | MER02000BYPNKABN01 | Pressure switch for industrial automation | |
| Honeywell 89028 4 Industrial Pressure Sensor | USD 23.95 | New | 103716 / 8902842131 | Industrial pressure sensor |
Where Each Product Wins
The Honeywell MER02000BYPNKABN01 wins when you want a pressure switch with a clear automation role. It includes the box shown in the unit's photos, and its description points to industrial automation, hydraulic, pneumatic, and pressure-monitoring applications, making it the stand-out choice for switch-driven tasks.
The Honeywell 89028 4 wins when you want the lower end of the price range and a condition stated simply as New. It is identified as an industrial pressure sensor, so for a pressure-sensing project that doesn't call for a switch style, the 89028 4 keeps the purchase straightforward.
Product Notes
Honeywell MER02000BYPNKABN01 Pressure Switch

The Honeywell MER02000BYPNKABN01 is an industrial pressure switch carrying model number MER02000BYPNKABN01 and arriving as new surplus stock with the box shown in its photos. That makes it the clearer choice when your control setup expects a discrete pressure switch instead of a sensor. The limitation is the condition detail: it is New - Open box, and the condition notes mention possible minor cosmetic marks, shelf wear, or packaging wear from storage. If your project can tolerate surplus cosmetic characteristics, the switch provides the defined switching role; if you need a pristine unopened item, the switch doesn't promise that.
Honeywell 89028 4 Industrial Pressure Sensor

The Honeywell 89028 4 stands out as an industrial pressure sensor with a clear application label. Its title identifies model 103716 and MPN 8902842131, and the application is marked Industrial. It is a good fit when you want a Honeywell pressure sensor. The limitation is its sensor identity: the 89028 4 is not a pressure switch, so if your wiring needs a discrete switching action, the MER02000BYPNKABN01 is the item that explicitly answers that. For straight sensing tasks, the 89028 4 gives you a clean path with a clear industrial role.
Final Choice by Use Case
Pick the Honeywell MER02000BYPNKABN01 Pressure Switch for industrial automation, hydraulic, pneumatic, or pressure-monitoring applications where a switch action is the goal. Pick the Honeywell 89028 4 Industrial Pressure Sensor for industrial sensing tasks where a straightforward sensor is the goal. In short: switch-first projects belong with the MER02000BYPNKABN01; sensor-first projects belong with the 89028 4.
