The Pickering Series 97 is a dual-in-line reed relay designed for switching up to 10 watts in dry configurations and 50 watts in mercury wetted versions, with pin-compatible options for both types. The 97-1-A-5/1D variant is a 1 Form A (energize to make) dry reed relay with a 5 V coil, 500 Ω coil resistance, and a maximum contact current of 1.2 A at 200 V. It is encapsulated in a plastic package with a mu-metal magnetic screen and epoxy resin housing, which protects the glass-to-metal seals from manufacturing stresses. The relay supports 108 switching operations at low loads and has a standard operating temperature range of -20 to +85 °C. The pin configuration follows a standard 14-pin DIL layout with pin identification marked for polarity-sensitive operation when a diode is fitted.
The Series 97 is a range of reed relays with pins in the popular Dual-in-Line format.
Being encapsulated in a plastic package using a very high resistivity epoxy resin gives the device several advantages over the more usual moulded construction. The reed switches are not subjected to the high temperatures and pressures of the transfer moulding process with the inherent risk of damage to the sensitive glass to metal seals. The construction incorporates a mu-metal wrap around the operating coil to eliminate magnetic interaction problems. Higher drive levels are achieved, allowing a full range of switching configurations including 1 or 2 Form A (energize to make), Form C (change-over) and Form B (energize to break) in both dry and mercury wetted types.
If higher coil resistance levels are required, please look at our Series 98 DIL relays which may be driven directly from 74HC or 74HCT CMOS logic.
