NoTES:
. Vibration (sinusoidal): MIL-STD-202, method
204, test condition D (except frequency shall
be 0 to 2,500 Hz). 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, test 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).
2. 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 μs
maximum closure for open contacts.
3. Dimensions are in inches. Metric equivalents
in parentheses for reference only.
4. unless otherwise specified, tolerance is ±.00
(0.25mm).
5. Indicated terminal is marked with a
contrasting bead.
6. 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.
7. When latching relays are installed in
equipment, the latch and reset coils should
not be pulsed simultaneously.
8. Each relay possesses high-level and low-
level capabilities. However, relays previously
tested or used above 0 mA resistive at
6 Vdc maximum or peak ac open circuits not
recommended for subsequent use in low-level
applications.
9. Relays may be subjected to 260°C ( minute)
peak solder reflow temperature.
0. 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
level (percent per 0,000 cycles): L = 3.0;
M = .0.
