DESCRIPTION

The Ser ies J255/255 is a n industry- standard ,half­ size, latchingcrystalcan relay.It has a wide range of sw itchingcapabilities ranging from low levelto 2 amps. The Series J255/255 latching relay configuration is double-p oledouble-th row (DPDT), so the relay offers excellentsw itching densityand versatility. Teledyne R elays'SeriesJ255/255 offers:

  • Allw eldedconstruction
  • Wireleads,gold-platedorsolder-coa ted
  • Matched seal for superior hermeticity
  • Gold-pl ated contactassembly
  • Mo dernizedassem blyprocess
  • Advanced cleaning techniqu es The 256, 257 and 258 variationsof the 255 feature different schematics. © 2007 TELED YNE RE LAYS (800) 284-7007 · w ww .teledynerelays.com J255 Page 1 J255\\042007'01

Contact chatter shall not exceed 0 μs maximum for closed contacts, and μs maximum closure for open contacts. Vibration (random): MIL-STD-202, method 24, t est condition IG. Contact chatter shall not exceed 0 μs maximum for closed contacts, and μs maximum closure for open contacts (applicable to qualification and group C testing only). Shock (half-sine pulse): MIL-STD-202, method 23, test condition C (00 g’s). Contact chatter shall not exceed 0 μs maximum for closed contacts, and μ s maximum closure for open contacts. Dimensions are in inches. Metric equivalents in parentheses for reference only. unless otherwise specified, tolerance is ±.0 0 (0.25mm). Indicated terminal is marked with a contrasting bead. unless otherwise specified, relays will be supplied with either gold-plated or solder- coated leads. The slash and characters appearing after the slash are not marked on the relay. When latching relays are installed in equipment, the latch and reset coils should not be pulsed simultaneously. Each relay possesses high-level and low- level capabilities. However, relays previously te sted or used above 0 mA resistive at

6 Vdc maximum or peak ac open circuits not

recommended for subsequent use in low-level applications. Relays may be subjected to 260°C ( minute) peak solder reflow temperature. For hi-rel applications, contact factory at (800) 284-7007. . The suffix letter L and M to designate the applicable failure rate level shall be added to the applicable listed dash number. Failure rate le vel (percent per 0,000 cycles): L = 3.0; M = .0. 2.
