FEATURES

• SoftCenter™ construction (see opposite)
• Highest quality instrumentation grade switches
• Encapsulated in patented mu-metal can
• Insulation resistance greater than 1012 ohms for Form A devices
• Dry and mercury wetted switches available
• Wide range of switch confi gurations - 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 and 24 volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance

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.

Both dry and mercury wetted switches are available in a wide range of confi gurations, 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).

Pickering Electronics - A Brief History

Pickering Electronics was formed in January 1968, with the aim to design and manufacture high quality reed relays, intended principally for use in Instrumentation and Test equipment.

Today, Pickering's Single-in-Line (SIL) range is by far the most developed in the relay industry with relays 25% the size of many of their competitors. The small SIL relays are sold in high volumes to large ATE companies throughout the world.

Pickering relays have many advantages over the more usual 'Hard Moulded' construction. They are constructed using SoftCenter TM technology which greatly reduces stress on the delicate glass reed switch capsule for maximum life and performance. Mu-metal magnetic screening allows high packing density without the risk of problems due to magnetic interaction between relays. Pickering Electronics is an ISO 9001 certified company.

Due to the unique nature of our relays, much of our production machinery is designed and manufactured by our engineering staff. Above is part of the production equipment used in the manufacture of our popular Series 109P Single-in-Line relay. This is the finishing stage in the production of the popular Series 109P relay. The relay enters this stage from the right. The unwanted part of the leadframe (the salvage bar) is removed leaving the connection pins of the relay at the finished length. The relay is then removed from the salvage plastic part and moves on to have the part number and Pickering name printed on the top face. After this, the relay passes an ink jet print head which applies the date code to the side of the relay. The finished part exits this stage and is passed to our Test Department for thermal cycling and Final Test. We do not sample test. All Pickering relays are tested for every operating parameter.
