ORDERING INFORMATION

1a1b/2a 8A polarized power relays ST RELAYS VDE

FEATURES

  1. Even with small form factor, sensitive enough for direct IC- driving The dimensions of this high-density 4- gap balanced armature are 31 mm × 14 mm × 11 mm 1.220 inch × .551 inch × .433 inch. Despite this small size, high sensitivity is achieved by a mechanism that incorporates high- efficiency polarized magnetic circuits along with our exclusive spring alignment method. With an minimum operating power of about 150 mW, nominal operating power of 240 mW, this relay can be directly driven by transistor or chip controllers. RoHS compliant 2. High switching capability High contact pressure, low contact bounce, and forced separation structure that radically improves resistance to contact welding (1 Form A 1 Form B type equivalent to TV-3). Strong against lamp inductive loads, maximum switching capacity has reached 3,040 VA (8A 380V AC). 3. High breakdown voltage – Optimal for control in 250 V power circuits High breakdown voltage has been achieved. Between contacts and coil of 3,750 Vrms; Surge breakdown voltage between coil and contact of 6,000 V, and between open contacts of 1,200 Vrms mean that these relays are suitable even for 250 V power circuit control. 4. Improved stability Conforms to all types of safety standards. Insulating distance of more than 3 mm secured. Complies with Japan Electrical Appliance and Material Safety Law requirements for operating

200 V power supply circuits, and

conforms with UL, CSA and VDE standards. 5. Latching types available In addition to single side stable types, convenient 2 coil latching types with memory functions are also available. Moreover, we offer 2 Form A specifications which, with double pole switching for applications such as 250 V power circuit switching, can enable safer designs. 6. Automatic cleaning possible The sealed design means that these relays can undergo immersion in automatic washing systems and are suitable for automatic soldering. Even in difficult environments, the contacts remain reliable. 7. Easy to design PC board patterns Features 4/10 dual-in-line terminals. Because the lead spacing has a pitch greater than 7.54 mm .297 inch, designers can make easy adjustments with the width of the land size. This, along with the large insulation distance, simplifies the drawing of PC board patterns. 8. To improve soldering efficiency, preapplication of solder to the terminals is recommended. 9. Sockets are available.

(Deenergized condition) (Reset condition) CAD Data 1. PC board patterns for 2 coil latching types When applying relays in power supply operation circuits for finished products regulated by the Electrical Appliance and Material Safety Law, use the pattern shown below. 2. Soldering should be done under the following conditions: 250°C 482°F within 10s 300°C 572°F within 5s 350°C 662°F within 3s 2) For automatic cleaning, the boiling method is recommended. Avoid ultrasonic cleaning which subjects the relays to high frequency vibrations, which may cause the contacts to stick. It is recommended that a fluorinated hydrocarbon or other alcoholic solvents be used. 3. When using, please be aware that the a contact and b contact sides of 1 Form A and 1 Form B types may go on simultaneously at operate time and release time. 1Terminal No. 2 3 4
