Quick Verdict
If your application involves monitoring machine guards, safety gates, or doors in an industrial automation environment, the Pilz PSEN ma1.4 lot is the purpose-built choice. It arrives with three sensors, one -50 actuator, two -52 actuators, and M8 quick-connect cabling. If your task is manual control input such as a knob dial with a push switch, the dual axis rotary encoder delivers that function at a listed price of $29.99.
At a Glance
| Detail | Pilz PSEN ma1.4 set | Dual Axis Rotary Encoder |
|---|---|---|
| Listed price | $250.00 | $29.99 |
| Function | Magnetic safety sensors with coded actuators for guard monitoring | Dual axis rotary encoder with integrated knob switch |
| What's included | 3 sensors, 1 -50 actuator, 2 -52 actuators | Optional 2/4/6/10-piece quantity |
| Notable spec | M8 quick-connect cable | 30 positioning number, 15 pulse, 8mm base height |
Where Each Product Wins
Choose the Pilz PSEN ma1.4 set if your priority is a safety interlock for machine guards. The three-sensor lot and two actuator variants are built for reliable position monitoring, and the M8 quick-connect fittings align with industrial cabling.
Choose the dual axis rotary encoder if you need a compact, low-cost manual control. The integrated knob switch, dual-axis rotation, and 30-position/15-pulse output give you a straightforward way to add operator input. The $220.01 price gap between the two makes the encoder a much lighter upfront investment.
Product Notes
Pilz PSEN ma1.4 Magnetic Safety Switch Sensor Set (3-Pack)
This lot of three Pilz PSEN ma1.4 magnetic safety switch sets is listed at $250.00 and includes three PSEN ma1.4-10mm sensors, one -50 actuator, and two -52 actuators. Because the actuators have slight mounting and orientation differences, you gain flexibility when installing them across multiple guard doors or gates. The sensors come with attached cables terminating in M8 quick-connect fittings, so you can run them into a control cabinet without a separate connector search. The main limitation is price: $250.00 is a serious outlay when you are only stocking spare parts. Additionally, the condition is listed as new open box, so the original boxes may be opened even though the components are unused.
Dual Axis Rotary Encoder With Switch (30 Positioning Number, 15 Pulse)
At $29.99, this rotary encoder is a low-cost way to add operator input to a panel or bench setup. The listing lets you choose 2, 4, 6, or 10 pieces, which makes it practical for projects that need several encoders or a few spares. It combines dual-axis rotation with an integrated knob switch, so one component handles both turning and pressing. The 30-position, 15-pulse output is suitable for menu navigation, volume control, or position adjustment, and the metal body with green and silver finish gives it a solid feel. The limitation is batch variability: the listing warns that text labeling may not match the images, colors can differ, and manual measurement tolerances of 0.5-1cm can apply. So it is better for prototyping and non-critical builds than for installations that require exact visual or dimensional consistency.
Final Choice by Use Case
- Industrial guard interlock and machine safety: Go with the Pilz PSEN ma1.4 set. The three sensors, mixed actuators, and M8 cabling fit a safety monitoring system, and the $250.00 price reflects a purpose-built lot.
- Control panel dial, encoder knob, or DIY input: Go with the dual axis rotary encoder. At $29.99, you get rotation and push-button control, plus the option to buy more pieces. Just account for possible batch variation.
- Mixed automated setup: Use the Pilz sensors for guard doors and the rotary encoder for operator-facing controls. They serve different points in the same machine.
