CHARACTERISTICS
SIL Series
Single-In-Line Reed Relays reduce the required
space to a minimum. Requiring only half the PCB
area of the DIP or DIL series, the SIL relays offer all
the advantages of Reed Technology.
• High resistance coils of up to 2000 Ω at 12 VDC
• Breakdown voltage coil / contact of up to 4.25 kVDC
• Contact form 1A, 1B or 1C
