When you're choosing between sensors for an automation project, the first question is whether you need a general position/motion sensor or a dedicated safety component. That's exactly the fork in the road here. The Honeywell C0401196 is a 10K Ohm resistive and optical position sensor aimed at general motion sensing, while the Schmersal BNS 33-12ZG is a magnetic safety sensor built for machine safety control. Both are new, but they are not interchangeable; your decision should start with the application.
Quick Verdict
The Honeywell C0401196 is the general-purpose option, combining resistive and optical sensing for position and motion feedback. The Schmersal BNS 33-12ZG is the specialist, built for machine safety control. If your project needs basic position monitoring, the Honeywell gives you the sensing modes you need. If the sensor will be part of a safety circuit or guard monitor, the Schmersal is the one designed for that role.

Where Each Wins
- Honeywell C0401196 wins on sensing versatility. It pairs a 10K Ohm resistive element with optical sensing, and its listed attributes include a 1-10 V coil voltage, AC current below 1 A, blue housing, and app-controlled operation. That makes it a flexible building block for a motion feedback loop.
- Schmersal BNS 33-12ZG wins on application fit for safety. It is explicitly a magnetic safety sensor for machine safety control, so in a machine guarding or interlock context, this is the product aimed at that responsibility.
Product Notes
Honeywell C0401196 Industrial Motion & Position Sensor
This Honeywell sensor is the more approachable pick when you're outfitting a motion or position feedback loop. The 10K Ohm resistive element can be paired with optical sensing, giving you two sensing principles in one package. Attributes include a blue finish, 1-10 V coil voltage, AC current rated below 1 A, and app-controlled functionality. For many industrial circuits, that's a practical specification set, especially for low-power AC applications. The limitation is that it's a general-purpose motion and position component, not a machine safety control device. If your application calls for a dedicated safety sensor, this one's role is different. It shines for projects where price is a major factor and basic position monitoring is the goal.
Schmersal BNS 33-12ZG Magnetic Safety Sensor
The Schmersal BNS 33-12ZG comes in as the more specialized option. It is identified as a magnetic safety sensor for machine safety control, which makes it the component you'd reach for when a guard door, interlock, or safety circuit needs a magnetic sensing element. It's a new unit, and the ID179748 part number helps lock down the reference. The trade-off is the larger share of the price spread: you're paying more for a narrower function. For a general position feedback task, it would be overkill. If your control system is built around Schmersal safety sensors, this BNS 33-12ZG fits naturally; otherwise, reserve it for applications that truly need a magnetic safety sensor.
Final Choice by Use Case
- For position and motion sensing when price matters most: Choose the Honeywell C0401196. It gives you both resistive and optical sensing in one unit at a price that is 74% lower than the Schmersal.
- For machine safety control and interlock-style tasks: Choose the Schmersal BNS 33-12ZG. Its magnetic safety sensor design is built for the safety side of automation, and that's worth the higher price when the job demands it.
