You will find that the Potter & Brumfield relay has a straightforward footprint that many boards accept easily.
I like how the heavy duty housing protects the coil, even the panel sees bumps and knocks sometimes.
Because it is black, the relay looks uniform when you group several units together in a row.
You will find that the 40ISR model is easy to reference during long projects.
The Hella brand on this relay is a nice touch and shows attention to detail overall.
