INTRODUCTION FLYER Power Relay F7 A Latching TE Connectivity presents its first bistable automotive plug-in relay in the maxi class. The power relay F7 A latching is a bistable single-coil version realized with a permanent magnet. It expands the TE bistable relay portfolio with a plug-in version in the maxi class. Bistable relays only need a short pulse of energy applied to the coil to change the switching state. It is not necessary for power to remain applied in order to maintain the switched state. Power con- sumption is very significantly reduced, especially for applications that must remain switched on over a long period of time. Power relay F7 A latching and other bistable relays offer several advantages over monostable (non-latching) variants. The decreased coil power requirement in bistable relays translates to reduced temperature rise. This means at the same ambient temperature a bistable relay can conduct higher continuous current than a monostable relay. If a bistable relay and a monostable relay are carry- ing equal continuous currents, the bistable relay may be used at higher ambient temperature. Additio- nally, the vehicles energy consumption and thus the CO emissions are considerably reduced. 2 Given that relays consume up to 10% of a vehicles electric power, the power relay F7 A latching offers considerable energy saving potential within the vehicle. www.te.com relays.te.com APPLICATIONS Power Relay F7 A Latching Cross carline, e.g. - Power outlet switch off - Start-stop - Energy management CONTACT DATA Contact arrangement: 1 form A (NO) contact Rated voltage: 12VDC Limiting continuous current: 80A at 23C, 60A at 85C, 35A at 125C Limiting making/breaking current: 300/70A Limiting short-time current overload current, ISO 8820-3: 1.35 x 50A, 1800s 2.00 x 50A, 5s 3.50 x 50A, 0.5s 6.00 x 50A, 0.1s Contact material: silver based Set/reset time: 2/1ms 7 Mechanical endurance: >1x10 operations KEY FEATURES COIL DATA Magnetically latched, ISO plug-in Magnetic system: bistable, single coil system relay Rated coil voltage/power: 12VDC One coil with set and reset function Max. coil temperature: 155C Pin assignment similar to ISO 7588 Polarity for set/reset energization: - pin 2, + pin 1/- pin 1, + pin 2 part 1 INSULATION DATA 60A continuous current at 85C Initial dielectric strength Customized versions available (color, - between open contacts / contact and coil / adjacent contacts: 500Vrms parallel or serial components etc.) Mini version (40A with 6.3mm OTHER DATA terminals) available on request Category of environmental protection, IEC 61810: RT1 dustproof Degree of protection, IEC 60529: IP54 dustproof Terminal type: Plug-in, quick connect DIMENSIONS AND TERMINAL ASSIGNMENT Dimensions Terminal assignment 1 form A, NO Latching MORE INFORMATION Tyco Electronics AMP GmbH a TE Connectivity Ltd. company TE Relay Products AMPrestr. 12-14 64625 Bensheim / Germany Phone: +49-(0)6251-133-0 Fax: +49-(0)6251-133-1600 View of the terminals (bottom view) www.te.com relays.te.com
