The Series 107 Mini-SIL range of reed relays are intended for stacking on 0.2 inches (5.08mm) pitch.
Single or double pole Form C (changeover) reed relays switching 0.25 Amps at 3 Watts
Their small size, superb contact resistance stability and ultra high insulation resistance, make these relays an ideal choice for high quality instrumentation.
The mu-metal case ensures virtually total magnetic screening, see explanation below.
Both dry and mercury wetted switches are available in a wide range of configurations.
If even greater packing density is required, smaller devices are available in other Pickering SIL ranges (except for two pole changeover types).
Magnetic Interaction - An explanation
Magnetic interaction between relays is normally expressed as a percentage increase in the voltage required to operate the relay, due to the extraneous fields from adjacent relay coils.
An unscreened SIL relay of this size would have an interaction figure of around 30 percent, i.e. the voltage required to operate it will increase by this amount when relays alongside are operated also. It may prove impossible to use such a relay at its nominal coil voltage in high density applications.
