RI-01C Series Dry Reed Switch

*

The Contact Resistance is measured using the Kelvin Method next to the glass body.

Vibration

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.

Mechanical Strength

The robustness of the terminations is tested in accor-

dance with “IEC 68-2-21”, test Ua

Operating and Storage Temperature

Operating ambient temperature; min: -55°C; max:

+125°C. Storage temperature; min: -55°C; max:

+125°C. Note: Temperature excursions up to 150°C

may be permissible. For more information contact your

nearest Coto Technology sales office.

Soldering

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.

Welding

The leads can be welded

Mounting

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.
