When you're shopping for sensors encoders and machine safety components, a stop motion detector needs to do one thing clearly: sense when motion stops and support machine interlocking. The challenge is finding a unit that's ready to wire, fits your physical space, and comes with an acceptable condition for its price.
Quick verdict
The Allen Bradley CU2 prewired stop motion detector with a 3-way interlock release is a used, US-made unit priced at USD 185.52. It brings together a prewired design, a three-way interlock release, and a footprint of 25 inches wide by 8 inches high. For someone who needs a replacement stop motion detector and is comfortable with a pre-owned component, this is a solid candidate to evaluate.
Who it suits
- Machine maintenance teams working with stop motion detection and interlock release mechanisms.
- Buyers who want a prewired unit to minimize wiring steps.
- Anyone specifically looking for a used Allen Bradley CU2 or a US-manufactured safety component.
Notable features
The prewired label is the most useful detail. Instead of buying a bare detector and assembling cables separately, this unit arrives as a stop motion detector with a 3-way interlock release already in place. The physical size-25 inches by 8 inches-gives a clear idea of the mounting envelope. The price of USD 185.52 is set for this used unit, and the country of manufacture is the United States.
Meaningful trade-offs
The used condition is the main trade-off. For a safety-related component, pre-owned status raises questions about wear and handling, and your comfort level with that is central to the decision. If a new or recertified unit is required for your process, this pre-owned option may not be suitable.
Prewired Stop Motion Detector Safety Machine with 3-Way Interlock Release
This is the product at the center of this guide. Choose it if you want a prewired stop motion detector with a three-way interlock release and you accept the used condition as part of the trade-off. The main limitation is that it is a pre-owned unit, so your confidence in a previously installed safety device becomes the determining factor.
Bottom line
If your machine setup needs a prewired stop motion detector with a 3-way interlock release, and your space can accommodate a 25-inch by 8-inch footprint, the Allen Bradley CU2 at USD 185.52 is worth a close look. Just confirm that a used US-made safety component meets your requirements before moving forward.
