The Series 97 is a dual-in-line reed relay with a plastic encapsulated package and mu-metal magnetic shielding. The 97-1-A-24/1 variant has a 24 V coil with 3000 Ω resistance and an integrated flyback diode. It uses a dry switch rated for 10 W at 300 V and 1.2 A maximum current. The package measures 18.8 mm × 9.4 mm × 10.7 mm with 7.62 mm pin spacing. Operating temperature is -20 to +85 °C, with a typical life of 10^8 operations under low-load conditions. Coil polarity must be observed due to the internal diode.
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.
