RI-07 Series

RI-07 S

ERIES

Pico dry-reed switch hermetically sealed in a gas-filled glass envelope.
Single-pole, single-throw (SPST) type, having normally open contacts,
and containing two magnetically actuated reeds.

The switch is of the double-ended type and may be actuated by an
electromagnet, a permanent magnet or a combination of both.

The device is intended for use in relays, sensors, pulse counters or
similar devices.

RI-07 Series

ECHANICAL

ATA

Contact arrangement is normally open; lead finish is tinned;
net mass is approximately 0.10 g; and can be mounted in any
position.

HOCK

The switches are tested in accordance with "IEC 68-2-27", test
Ea (peak acceleration 150 G, half sinewave; duration 11 ms).
Such a shock will not cause an open switch (no magnetic field
present) to close, nor a switch kept closed by an 80 AT coil to
open.

IBRA

IBRATION

TION

The switches are tested in accordance with "IEC 68-2-6", test
Fc (acceleration 10 G; below cross-over frequency 57 to 62
Hz; amplitude 0.75 mm; frequency range 10 to 2000 Hz,
duration 90 minutes). Such a vibration will not cause an open
switch (no magnetic field present) to close, nor a switch kept
closed by an 80 AT coil to open.

ECHANICAL

TRENGTH

The robustness of the terminations is tested in accordance with
"IEC 68-2-21", test Ua

(load 10 N).

OLDERING

The switch can withstand soldering heat in accordance with
"IEC 68-2-20", test Tb, method 1B: solder bath at 350 �10� C
for 3.5 �0.5 s.
Solderability is tested in accordance with "IEC 68-2-20" test

ELDING

The leads can be welded

OUNTING

The leads should not be bent closer than 1 mm to the glass-to-
metal seals. Stress on the seals should be avoided. Care must
be taken to prevent stray magnetic fields from influencing the
operating and measuring conditions.
