One is a wired motion and position sensor. The other is a wireless temperature monitor. If you're choosing between them, the decision comes down to what you need to measure, not which is "best" in general. The Honeywell C0401196 offers 10K Ohm resistive and optical motion/position sensing with an AC signal, while the Monnit MNS2-9-IN-TS-ST-L03 senses temperature over a 900 MHz wireless link with a 3-foot lead. This head-to-head lays out their prices and roles for your sensor, encoder, and machine safety work.
Quick verdict
Go with the Honeywell C0401196 if you need wired position feedback at a lower price ($39.99) and a new unit. Go with the Monnit MNS2-9-IN-TS-ST-L03 if you need wireless temperature monitoring on a Monnit system ($100.00, including battery, antenna, mounting hardware, and a 3-foot lead). Neither sensor wins broadly; the right choice is the one that captures the signal your application needs.
Cost and fit at a glance
| Sensor | Price | Condition | Primary Role | Power / Signal |
|---|---|---|---|---|
| Honeywell C0401196 | $39.99 | New | Motion and position sensing (10K Ohm resistive & optical) | AC, 1-10 V coil voltage, under 1 A |
| Monnit MNS2-9-IN-TS-ST-L03 | $100.00 | New - Open box | Wireless temperature sensing with 3-foot lead | 900 MHz wireless; 3V industrial battery included |
Where Honeywell C0401196 wins
The Honeywell C0401196 wins for any job centered on motion or position. Its list price is $39.99, well below the Monnit's $100.00, and it is marked new. The 10K Ohm resistive and optical design gives two sensing paths in one unit, and the AC rating with 1-10 V coil voltage and under 1 A draw fits a conventional hardwired control loop. If your machine safety setup already uses wired sensors and you don't need wireless data, this is the simpler and less expensive pick.
Where Monnit MNS2-9-IN-TS-ST-L03 wins
The Monnit MNS2-9-IN-TS-ST-L03 wins when temperature is the variable to track. It communicates over 900 MHz, so it works as a remote monitoring node, and the included 3-foot lead positions the probe a short distance from the transmitter. The kit contains mounting hardware, a pre-installed 3V industrial battery, and an SMA antenna, so it is essentially a complete package for a Monnit system. At $100.00, it costs more than the Honeywell, but it provides a different capability: wireless temperature visibility.
Product notes
Honeywell C0401196
At $39.99, the Honeywell C0401196 is the lower-priced option and the only one here that handles motion and position detection. The title calls out 10K Ohm resistive and optical sensing, so you get two sensing approaches in a single blue unit. It is rated for AC operation with a 1-10 V coil voltage and under 1 A current draw, which points to a straightforward hardwired control signal. It is listed as new, which is a plus for controlled installations. The main limitation is that it doesn't measure temperature and it has no wireless output, so remote monitoring isn't possible with this unit. The extra "App-Controlled" feature is hard to reconcile with a wired industrial sensor, so it shouldn't drive the buying decision. For a position sensor that works with conventional wiring, this Honeywell delivers at a favorable price.
Monnit MNS2-9-IN-TS-ST-L03
The Monnit MNS2-9-IN-TS-ST-L03 is the wireless temperature specialist, priced at $100.00. It operates on 900 MHz and has a 3-foot lead for the temperature probe. The package includes mounting hardware, a pre-installed 3V industrial battery, and an SMA antenna, so you have everything needed to deploy the node. The condition is New - Open box, which means the packaging may not be factory sealed, but the sensor is described as new and industrial rated. Its limitation is scope: it is a temperature sensor, not a position or motion sensor, and it is built for use with a Monnit system. If your monitoring network isn't Monnit-based, this unit won't be useful. For a Monnit wireless temperature deployment, though, it is the complete package.
Final choice by use case
If you need to sense motion or position on a machine or process line, pick the Honeywell C0401196. It costs $39.99, is new, and uses 10K Ohm resistive and optical sensing with a wired AC signal. If you need to monitor temperature remotely on a Monnit wireless network, pick the Monnit MNS2-9-IN-TS-ST-L03. It costs $100.00 and includes the battery, antenna, mounting hardware, and 3-foot lead; the open-box condition is the only tradeoff to weigh. Match the sensor to the variable you must measure, and the decision is clear.
