When you're protecting machinery, the first decision isn't which brand to pick-it's what kind of hazard you need to sense. A moving press brake or sliding table creates a pinch point that should trigger a stop when touched. A guard door or safety gate creates an access point that should interlock until the machine is safe. These two very different jobs are what separate the Industrial Safety Edge Sensor Strip Contact Ribbon Switch and the Pilz (x3) PSEN ma1.4 Magnetic Safety Switch Sensor Sets.
Quick verdict
If your machine needs edge protection that reacts to contact, the Industrial Safety Edge Sensor Strip is the lower-cost pick. If you need to monitor three separate guard doors with coded magnetic switches, the Pilz lot is the more complete package.

Where each product wins
The Industrial Safety Edge Sensor Strip wins on price and on simplicity for single-edge applications. It gives you a pressure-sensitive ribbon switch for $29.96, so it's an easy way to add contact sensing to one hazard point.
The Pilz lot wins when you need coded magnetic interlock monitoring. It includes three complete sensor/actuator sets, which is helpful when you have multiple access points. The mixed actuators give you mounting flexibility: the -50 and -52 variants work with the same PSEN ma1.4 sensors but differ in mounting/orientation, as described in the listing.
The Pilz lot also has the edge for wiring into a control system: the sensors come with attached cables and quick-connect fittings. The ribbon switch is a single sensing element, so it's less about multi-point coverage and more about adding a contact edge to one specific area.
Product notes
Industrial Safety Edge Sensor Strip Contact Ribbon Switch
For one edge hazard, this contact ribbon switch is the straightforward, lower-cost route. The listing positions it as a safety edge sensor strip and contact ribbon switch, which is what you'd use when a machine part has to stop on contact. Priced at $29.96, it's a compact way to add pressure-sensitive protection without a large outlay. The trade-off is that it's a single strip, not a set, and the condition is described as new other, so it isn't presented as a factory-sealed unit. It's a sensible choice when you have one pinch point or edge to protect and you want to spend close to the minimum.
Pilz (x3) PSEN ma1.4 Magnetic Safety Switch Sensor Sets 506301 w/ -50 & (2) -52
This lot takes a more comprehensive approach to machine safety. For a higher price, you get three complete Pilz PSEN ma1.4 coded magnetic safety switch sets. Each set includes a PSEN ma1.4 sensor and one actuator; the lot ships with one -50 and two -52 actuators. The description breaks down the actuator mix clearly: all of them work with the same sensors and perform the same function, with slight mounting/orientation differences. That makes this a flexible package if you're instrumenting several guard doors at once. The sensors come with attached cables and quick-connect fittings, so you don't need to source separate connectors. The condition is new open box, which is a plus if you're looking for a complete lot at a set price. The main limitation is the mixed actuator orientation: if you want all three doors to use identical mounts, you'll have to work around the -50/-52 split. It's also the bigger upfront investment, but the multi-set quantity is what justifies it.
Final choice by use case
If your hazard is a pinch point or moving edge that needs to stop on contact, go with the Industrial Safety Edge Sensor Strip Contact Ribbon Switch. If your priority is monitoring multiple safety gates with coded magnetic interlocks, choose the Pilz PSEN ma1.4 lot. For a single edge, the ribbon switch saves money. For multi-point guard monitoring, the Pilz set's three complete kits and actuator flexibility make it the more useful package.
