Metal Package SIL Series 108 switch ratings - The contact ratings for each switch type are shown below: Switch No Switch form 1 A 2 A 10 W 0.5 A 1.2 A 200 10E9 0.5 ms 0.2 ms Low level 3 C 3 W 0.25 A 1.2 A 200 10E7 1.0 ms 0.5 ms Change over Switch no.2 is particularly good for switching low currents and/or voltages. It is the ideal switch for A.T.E. systems where cold switching techniques are often used. Where higher power levels are involved, switch no.1 is more suitable.

For example, for an ‘end of life’ contact resistance specification of 1 Ω, switching low loads (10 V at 10 mA resistive) or when ‘cold’ switching, typical life is approx 1 x 10 9 ops. At the maximum load (resistive), typical life is 1 x 10 7 ops. In the event of abusive conditions, e.g. high currents due to capacitive inrushes, this figure reduces considerably. Pickering will be pleased to perform life testing with any particular load condition. Note 2 Capacitance across open switch The capacitance across the open switch was measured with other connections guarded. Note 3 Capacitance values The value will depend upon on the mode of connection/guarding of unused terminals. Please contact technical sales for details.

Note: The upper temperature limit can be extended to +125 °C if the coil drive voltage is increased to accommodate the resistance/temperature coefficient of the copper coil winding. This is approximately 0.4% per °C. This means that at 125 °C the coil drive voltage will need to be increased by approximately 40 x 0.4 =16% to maintain the required magnetic drive level.

Metal Package SIL Pickering Series 107 Mini-SIL ® SIL/SIP Reed Re lays Up to 20 Watts switching Stacking on 0.2 inches pitch Features • SoftCenter ® construction (see adjacent diagram) • Highest quality instrumentation grade switches • Encapsulated in patented mu-metal can • Insulation resistance greater than 10 12 Ω for Form A devices • Dry and mercury wetted switches available • Wide range of switch configurations - 1 Form A, 1 Form B, 2 Form A, 1 Form C, and 2 Form C, see adjacent column • For R.F. or high speed digital applications, 50 ohms coaxial devices are available in the same package style, see Series 102M • 3, 5, 12 or 24 Volt coils with or without internal diode • 100% tested for dynamic contact resistance for guaranteed performance The Series 107 Mini-SIL range of reed relays are intended for stacking on 0.2 inches (5.08mm) pitch. 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, see adjacent column. 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. A Pickering Series 107 reed relay has an interaction figure of approximately 1 percent. Switch Ratings - Dry switches • Single or Double pole Form A (Energize to Make) relays. Up to 1 Amp switching at 20 Watts • Single pole Form B (Energize to Break) relays. Up to 1 Amp switching at 20 Watts • Single or Double pole Form C (Change-over) relays. 0.25 Amps switching at 3 Watts Switch Ratings - Mercury Wetted Switches • Single or Double pole Form A (Energize to Make) relays. 2 Amp switching at 50 Watts • Single pole, Non Position Sensitive, Form A (Energize to Make) relays. 2 Amp switching at 50 Watts Typical Pickering SoftCenter ® Construction TYPICAL PICKERING CONSTRUCTION Internal mu-metal magnetic screen Bobbinless self supporting coil to maximise magnetic drive Encapsulation Shell Soft inner encapsulation material to protect reed switch Hard outer encapsulation material Reed switch Diode TYPICAL COMPETITOR’S CONSTRUCTION Very hard moulding material No mu-metal magnetic screen High magnetic interaction with adjacent relays Coil winding Coil supporting bobbin, wastes space and reduces magnetic drive pickering email: sales@pickeringrelay.com pickeringrelay.com 33 107/08/16
