SICK RZT7-03ZRS-KP0 cylinder reed switch
A common problem with cylinder sensors is selection: one line may have T-slot, profile and round cylinders, even SMC CDQ2 types, and if one sensor cannot fit them all, several spare types must be stocked. The SICK RZT7-03ZRS-KP0 fits five cylinder slot types (T-slot, profile, tie-rod, round and dovetail) with one model and also fits SMC CDQ2 / ECDQ2 cylinders. It uses reed switch technology, is rated IP65 / IP67, runs on a wide 5–30 V AC/DC 3-wire supply and has an LED status indicator.

Key features
- Five slot types, one model: one part number covers T-slot, profile, tie-rod, round and dovetail cylinders, reducing the number of spare-part types.
- SMC CDQ2 / ECDQ2 compatible: direct replacement for users of these SMC cylinders.
- IP65 / IP67: withstands water jets and temporary immersion for washdown and wet lines.
- PUR drag-chain cable: withstands repeated bending in moving cable chains.
- LED status indicator: visual confirmation for quick troubleshooting.
- Reed switch sensitivity: typ. 3 mT with ≤0.1 mT repeatability for stable cylinder position signals.
Applications
- Stroke detection on T-slot / round cylinders
- Replacement on SMC CDQ2 series cylinders
- Moving drag-chain installations
- Pneumatic systems in washdown environments
- Pneumatic control circuits on automated equipment
- Standardizing maintenance spares
