RI-60 Series
RI-60 S
ERIES
Ultra-miniature 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.

Contact arrangement is normally open; lead finish is
tinned; net mass is approximately 0.09 g; and can be
mounted in any position.
S
HOCK
The switches are tested in accordance with “IEC
68-2-
27”,
test Ea (peak acceleration 100 G, half sinewave;
duration 11 ms). Such a shock will not cause an open
switch (no magnetic field present) to close.

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 Ta, method 3: solder globule temperature 235°C;
ageing 1b: 4 hours steam.
W
ELDING
The leads can be welded.
M
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.
