When you are choosing parts for an industrial control panel, the first question is not which brand is better; it is which component actually does the job. In relays, contactors, and industrial switches, you will often compare a timing component against a position-sensing component, and that is exactly what this head-to-head does. The USED AGASTAT INDUSTRIAL ELECTROPNEUMATIC TIME DELAY RELAY E7012PC002 is listed at $226.00, while the Square D 9007-CO3 Industrial Basic Snap Action Limit Switch 10A 600VAC is listed at $52.89. The price comparison puts the Square D 77% below the AGASTAT, but that gap only matters if the switch can handle the task the relay would have performed. The AGASTAT is made for delayed switching; the Square D is made for detecting contact.
Quick verdict: Choose the AGASTAT E7012PC002 when your sequence needs a time delay between input and output. Choose the Square D 9007-CO3 when your machine needs a limit switch to sense physical position. These two are not interchangeable, so the right choice starts with the required function, not the sticker price.
| Product | Listed Price | Relative Price | Core Function |
|---|---|---|---|
| AGASTAT E7012PC002 Time Delay Relay | $226.00 | Time delay relay | |
| Square D 9007-CO3 Limit Switch | $52.89 | Snap action limit switch |
Where each product wins
The AGASTAT relay wins when you need a dedicated timing function. It is the only time-delay component in this comparison, and that role makes it the more specialized option of the two. The higher price is easier to justify when the control sequence depends on that delay.
The Square D limit switch wins for straightforward position sensing. It brings a 10A rating at 600VAC, a DPDT-DB contact arrangement, and AWG 22 to AWG 14 wire compatibility, which gives a panel builder concrete electrical specs. It is also the lower-priced option, so it keeps the cost down when all you need is a mechanical switch that reacts to contact.
USED AGASTAT INDUSTRIAL ELECTROPNEUMATIC TIME DELAY RELAY E7012PC002
If your circuit needs a deliberate pause before the next action, the AGASTAT E7012PC002 is the relay to plan around. Its time-delay function is the reason to choose it: a standard limit switch cannot insert that delay into a sequence. The part number E7012PC002 gives you a specific AGASTAT unit to reference, and the used condition is the main trade-off, since this is a pre-owned component rather than a new one. The higher price also makes it a more deliberate purchase, so reserve this relay for projects where the timing role is clear.
Square D 9007-CO3 Industrial Basic Snap Action Limit Switch 10A 600VAC
The Square D 9007-CO3 is a straightforward snap-action limit switch with a brown housing and black plunger. The DPDT-DB contact configuration and the 10A/600VAC rating define its switching capability, and the AWG 22 to AWG 14 wire range helps you plan the connection. Choose it when a moving part needs to physically actuate a switch. The limitation is scope: this is a position-sensing device, not a timing relay, so it will not produce a time delay. It is also listed as new open-box, meaning the packaging has been opened even though the switch itself is new.
Final choice by use case
For a control circuit that has to react to mechanical movement, the Square D 9007-CO3 is the lower-priced, clearly specified limit switch to pick. For a control sequence that needs a timed pause between events, the AGASTAT E7012PC002 time delay relay is the specialized component to use. Let the machine's job decide, and the price spread will make sense.
