Miniature relays

November 2003 Operator Interfaces, Switches & Relays

The small dimensions of the new Erni dual-in-line relay permits compact arrangement of relays on PC boards. The relay may be soldered directly onto the PCB or mounted in a 16 pin DIP socket. Because of the plastic sealed construction (100% dustproof and watertight) they are suitable for automatic soldering.

REL 07 relays are fitted with two form C changeover contacts. Because of the construction and contacts plated with 10 microns of gold, the contact resistance remains stable during their entire life. The bifurcated contacts allow switching of low signals of 50 µA/100 mV up to medium loads of 2 A/250 V a.c./220 V d.c. with a maximum switching load of 125 VA/50 W.

They are suitable for switching and control functions within the entire low current range such as process control, measuring techniques, telecommunications and Hi-Fi audio applications. Coil voltages of 5, 6, 12, 24 or 48 V d.c. are available. Contact life expectancy is 107 switchings maximum.
