Automation Controls Catalog 1a1b/2a 8A polarized power ST RELAYS relays 2. High switching capability 6. Automatic cleaning possible High contact pressure, low contact The sealed design means that these bounce, and forced separation relays can undergo immersion in structure that radically improves automatic washing systems and are resistance to contact welding suitable for automatic soldering. Even (1 Form A 1 Form B type equivalent to in difficult environments, the contacts TV-3). Strong against lamp inductive remain reliable. loads, maximum switching capacity 7. Easy to design PC board patterns has reached 3,040 VA (8A 380V AC). Features 4/10 dual-in-line terminals. 3. High breakdown voltage Optimal Because the lead spacing has a pitch for control in 250 V power circuits greater than 7.54 mm .297 inch, High breakdown voltage has been designers can make easy adjustments achieved. Between contacts and coil of with the width of the land size. This, Protective construction: Sealed type 3,750 Vrms Surge breakdown voltage along with the large insulation between coil and contact of 6,000 V, distance, simplifies the drawing of PC and between open contacts of 1,200 board patterns. Vrms mean that these relays are 8. To improve soldering efficiency, 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 FEATURES Conforms to all types of safety are available 1. Even with small form factor, standards sensitive enough for direct Insulating distance of more than 3 mm ICdriving .118 inch secured. Complies with The dimensions of this high-density 4- Japan Electrical Appliance and gap balanced armature are 31 mm Material Safety Law requirements for 14 mm11 mm 1.220 inch.551 inch operating 200 V power supply circuits, .433 inch. Despite this small size, and conforms with UL, CSA and VDE high sensitivity is achieved by a standards. mechanism that incorporates 5. Latching types available highefficiency polarized magnetic In addition to single side stable types, circuits along with our exclusive spring convenient 2 coil latching types with alignment method. With an minimum memory functions are also available. operating power of about 150 mW, Moreover, we offer 2 Form A nominal operating power of 240 mW, specifications which, with double pole this relay can be directly driven by switching for applications such as 250 transistor or chip controllers. V power circuit switching, can enable safer designs.
