Choosing between two sensors in the sensors, encoders, and machine safety space can feel like comparing apples and oranges-especially when one is a contact ribbon switch and the other is a wireless temperature sensor. The Industrial Safety Edge Sensor Strip Contact Ribbon Switch fos Bus sells for $29.96, while the Monnit Industrial Wireless Temperature Sensor MNS2-9-IN-TS-ST-L03 sells for $100.00. The difference is $70.04, and it reflects two very different jobs: low-cost edge contact detection versus remote wireless temperature monitoring. Before you decide, ask yourself what signal your operation actually needs: "Is this edge being touched?" or "What's the temperature right now?"
Quick verdict
Pick the Industrial Safety Edge Sensor Strip when your priority is protecting a pinch point, door edge, or moving guard with a contact-style switch. Pick the Monnit sensor when you need temperature readings without walking over to the equipment. The Monnit option is the more complete package, and its higher price goes toward wireless-ready parts you would otherwise have to source separately.
At a glance
| Product | Price | What you get | Condition |
|---|---|---|---|
| Industrial Safety Edge Sensor Strip Contact Ribbon Switch | $29.96 | Contact ribbon switch for safety edge sensing | New other |

Where each product wins
- The Industrial Safety Edge Sensor Strip wins for lower upfront cost and direct contact-based edge detection.
- The Monnit Industrial Wireless Temperature Sensor wins for remote temperature monitoring and wireless-ready completeness.
Product notes
Industrial Safety Edge Sensor Strip Contact Ribbon Switch fos Bus
The lower-priced choice in this head-to-head is built around a simple concept: a contact ribbon switch that acts as a safety edge sensor strip. That makes it a sensible fit for protecting edges and pinch points in machinery where a physical contact signal is enough. Its condition is listed as "New other," so it's worth reading the condition details carefully. Choose it when you want an inexpensive way to detect contact along an edge without paying for wireless features you do not need. It is a straightforward contact switch for edge-sensing duty, and the lower asking price keeps the entry point low. If your application is edge contact detection, this is the simpler buy.
Monnit Industrial Wireless Temperature Sensor MNS2-9-IN-TS-ST-L03
The Monnit side of this comparison is a wireless temperature sensing package, and that completeness is the main reason to spend more. Included are a 3-foot lead, mounting hardware, a pre-installed 3V industrial battery, an SMA antenna, and 900 MHz operation for the US market. This makes it well suited for industrial temperature monitoring where the sensor needs to communicate wirelessly. It is designed for use with a Monnit system, so plan around that ecosystem. Condition is listed as "New - Open box," meaning the packaging has been opened but the components are as described. Go this route when you want remote temperature readings and a ready-to-deploy wireless sensor.
Final choice by use case
Choose the Industrial Safety Edge Sensor Strip Contact Ribbon Switch fos Bus if your purchase decision hinges on low-cost edge contact detection. Choose the Monnit Industrial Wireless Temperature Sensor MNS2-9-IN-TS-ST-L03 if you need wireless temperature monitoring and want a ready-to-deploy wireless sensor.
