PCB relays: Songle/SANYOU SRD, Omron G5V, G2RL, G6K, Finder 40, Schrack RT
What are the dimensions of the SRD-05VDC-SL-C relay? · Standard part · basis: KiCad 3D models drawn from manufacturer datasheets (SANYOU SRD = the common Songle SRD-xxVDC blue relay)
- sizes
- 14 in table
Notes
- SRD-05VDC-SL-C (the Arduino module relay): 19.0 × 15.5 × 15.3 mm, 5 pins, 10 A contacts. Pin pattern: coil pins 6.0 mm apart on one end, contacts spread 12.0 mm.
- Omron G5V-1 (signal, 12.5 × 7.5 × 10 mm) and G5V-2 (DPDT, 20.5 × 10 × 11.5 mm) are the small ones; G2RL (29 × 12.7 × 15.7 mm) and Finder 40.52 (29 × 12.5 × 25 mm) are 8–16 A.
- Leave 2 mm around a relay in a printed enclosure; mains relays need creepage: 4 mm from contact pins to any slot.
