MFS Series Reed Relay
The MFS Series is an ultra-high-density reed relay engineered for compact PCB layouts and precision switching in space-constrained environments. With a vertical square form factor measuring just 4.35 × 4.35 mm, it offers the smallest footprint in its class, enabling up to 500 relays on an 8” board and 1,000 relays on a 12” board. This makes the MFS Series ideal for IC testing, automated test equipment (ATE), and high-density signal routing.
Available in SPST-NO (Form A) contact configuration, the MFS Series supports coil voltages of 5 VDC and 12 VDC, and is rated for up to 5 W, 50 VDC, and 0.2 A. Through-hole vertical mounting ensures secure integration, while optional diode protection, single or double shielding, and relay sockets enhance performance, isolation, and ease of maintenance.
