The Series 97 is a range of dual-in-line reed relays encapsulated in a plastic package with an internal mu-metal magnetic screen to prevent magnetic interference. The relays use a high-resistivity epoxy resin construction that protects the glass-to-metal seals from damage during manufacturing. Available in 1 Form A, 1 Form B, 2 Form A, or 1 Form C configurations, they support both dry and mercury-wetted switches with identical pinouts. The dry switch variants switch up to 10 watts at 200 or 300 volts, while mercury-wetted forms switch up to 50 watts at 500 volts. Coil voltages are 5, 12, or 24 volts, and internal diodes are optional. The package measures 18.8 mm length by 9.4 mm width. The operating temperature range is -20 to +85 °C, extendable to +125 °C with increased drive voltage. Mercury-wetted relays must be mounted vertically with pin 1 uppermost.
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.
