Automation Controls Catalog 1a1b/2a 8A polarized power ST RELAYS relays 6. Automatic cleaning possible 2. High switching capability The sealed design means that these High contact pressure, low contact relays can undergo immersion in bounce, and forced separation automatic washing systems and are structure that radically improves suitable for automatic soldering. Even resistance to contact welding in difcult environments, the contacts (1 Form A 1 Form B type equivalent to remain reliable. TV-3). Strong against lamp inductive 7. Easy to design PC board patterns loads, maximum switching capacity Features 4/10 dual-in-line terminals. has reached 3,040 VA (8A 380V AC). Because the lead spacing has a pitch 3. High breakdown voltage Optimal greater than 7.54 mm .297 inch, for control in 250 V power circuits designers can make easy adjustments High breakdown voltage has been RoHS compliant achieved. Between contacts and coil of with the width of the land size. This, 3,750 Vrms Surge breakdown voltage along with the large insulation between coil and contact of 6,000 V, distance, simplies the drawing of PC Protective construction: Sealed type and between open contacts of 1,200 board patterns. Vrms mean that these relays are 8. To improve soldering efciency, suitable even for 250 V power circuit preapplication of solder to the control. terminals is recommended 4. Improved stability 9. Sockets for PC board and soldering Conforms to all types of safety are available FEATURES standards Insulating distance of more than 3 mm 1. Even with small form factor, .118 inch secured. Complies with sensitive enough for direct IC- Japan Electrical Appliance and driving Material Safety Law requirements for The dimensions of this high-density 4- operating 200 V power supply circuits, gap balanced armature are 31 mm and conforms with UL, CSA and VDE 14 mm 11 mm 1.220 inch .551 inch standards433 inch. Despite this small size, 5. Latching types available high sensitivity is achieved by a In addition to single side stable types, mechanism that incorporates high- convenient 2 coil latching types with efciency polarized magnetic circuits memory functions are also available. along with our exclusive spring Moreover, we offer 2 Form A alignment method. With an minimum operating power of about 150 mW, specications which, with double pole nominal operating power of 240 mW, switching for applications such as 250 this relay can be directly driven by V power circuit switching, can enable transistor or chip controllers. safer designs.
