This GPS reed magnetic switch works well for many projects. It has both normally open (NO) and normally closed (NC) contacts in one unit. This three-wire setup makes it a flexible sensor. It can replace the PS-3150 switch directly. Features and Benefits
- Dual NO/NC Contacts - It gives you both a normally open and a normally closed circuit path. You can choose the logic your project needs.
- Three-Wire Configuration - The common, NO, and NC wires are clearly marked. This makes it easy to wire for either function.
- Flanged Mounting Case - The housing has two mounting tabs with screw holes. This helps you attach it securely to any flat surface.
- Encapsulated Switch Body - The reed switch itself is sealed inside the plastic housing. This protects it from bumps and environmental factors. Applications
- Security Systems - It works with alarm panels that need either normally open or normally closed sensors for doors and windows.
- Cabinet and Closet Lighting - Wire the normally closed contact to turn on an LED strip when a door opens. It turns off when the door closes.
- Industrial Process Control - Use it to see if parts are on a production line. It gives feedback to a control system.
What It Is
This is a Reed Switch, a type of magnetic control proximity sensor. It measures 23x14mm and is sold in a pack of five pieces. It functions as a replacement for the PS-3150. Proximity sensors detect the presence or absence of objects without physical contact. This particular reed switch operates with a maximum switching voltage of 200V and can handle a maximum switching current of 0.5A. The contact rating is 10W maximum.
Key Uses & Applications
Reed switches like this are used in a variety of industrial sensor applications where non-contact detection is required. Their small dimensions, 23x14mm, make them suitable for integration into compact electronics modules. They are often employed in security systems for door or window contacts, position sensing in machinery, or as limit switches. The Normally Open/Closed (NO/NC) switching action provides flexibility for different circuit designs, allowing for activation or deactivation upon magnetic field detection.
How to Choose
When selecting a reed switch, consider the required switching voltage (this model handles up to 200V) and switching current (up to 0.5A). The contact rating of 10W maximum is also important for compatibility with your circuit. For replacements, ensure the dimensions, 23x14mm, and the replacement for PS-3150 match your existing unit. To test a proximity sensor like this, you can use a multimeter to check for continuity changes across its terminals when a magnetic field is introduced and removed.

Quantity: 5 pieces. Replacement For: PS-3150. Sensor Type: Proximity Induction Sensor. Switching Action: Normally Open (NO) / Normally Closed (NC). Theory: Current Sensor. Type: Magnetic Sensor. Q: Can this GPS-23 switch be wired as either Normally Open or Normally Closed? A: Yes, it's a 3-wire switch with terminals for Common (COM), Normally Open (NO), and Normally Closed (NC). This gives you the flexibility to wire it for either configuration depending on what your circuit needs.. Q: What are the physical dimensions of this reed switch? A: The main body of the switch measures 23mm long by 14mm wide. It includes a mounting hole sized for an M3 screw, which makes it simple to attach to a panel or enclosure.. Q: Is this a suitable replacement for a PS-3150 sensor? A: Yes, the GPS-23 is designed to be a functional substitute for the PS-3150. It offers very similar electrical characteristics and physical dimensions for use in security systems and other proximity sensing jobs.. Q: Does this package include the magnet needed to activate the switch? A: No, this listing is for a 5-pack of the GPS-23 switches only. You will need to source a separate magnet to use with them.. Q: What kind of quality control do these switches go through? A: Each batch of switches is sample-tested to make sure they function correctly and meet their stated electrical specifications.
