Miniature 6 A power relay has high sensitivity

19 May 2004 Switches, Relays & Keypads Integrated Solutions

Fujitsu Components' miniature 6A-class power relay with high-sensitivity properties for industrial and programmable logic controller applications, has a 170 mW nominal coil power and a contact rating of 250 V a.c. The FTR-LY relay is designed with a minimum of piece parts and a coil terminal over-moulding to achieve compact configuration and high reliability.

As a result, the FTR-LY is 58% of the volume of the company's 8 A, 220 mW relay, the JS. The FTR-LY also has a 27,8 x 4,9 mm footprint that occupies less than half the JS's mounting space.

The FTR-LY features a minimum of 8 mm creepage and clearance distance from coil to contact, which provides high-insulation properties. The use of cadmium-free materials also meets the requirements of many environmental programs. A lead-free version of the relay is also available. It has a mechanical life of 10 million operations at 250 V a.c., 6 A resistive load (NO). Other specifications include a 1000 V dielectric strength between open contacts/4000 V between coil and contacts, 6000 V surge strength, and an operating temperature range of -40 to +85°C.
