Specifications
Ratings
Contact Rating: 30 VDC, 0.1 A (Minimum Appli-
cable Load: 5 VDC, 1 mA)
The above ratings conform to JIS C4505, for testing under the fol-
lowing conditions.
1. Load: Resistive load
2. Mounting conditions: No vibration or shock
3. Ambient temperature: 20
$2_C.
4. Operating frequency: 20 times/min.

Note:
1. The above ratings are for an ambient temperature of 25
°C.
2. The built-in LED lamp has no limiting resistor and so it is necessary to connect an external resistor within the range shown in the
above table. (For details of calculation formulas, refer to page 28.)
3. Refer to the characteristic graphs of VF – IF on page 24.
4. The same LED lamp is used for both yellow illumination and white illumination and so the ratings are the same.
Characteristics

min. (at 500 VDC)
Dielectric strength
1,000 VAC, 50/60 Hz for 1 minute between terminals of same polarity
g
2,000 VAC, 50/60 Hz for 1 minute between terminals of different polarity, and between each
terminal and ground
1,000 VAC, 50/60 Hz for 1 minute between lamp terminals (See note 2.)
Vibration resistance
Malfunction: 10 to 55 Hz, 1.5 mm double amplitude (See note 3.)
Shock resistance
Destruction: 500 m/s2
Malfunction: 150 m/s2 (See note 3.)
Life expectancy
Mechanical:
Momentary operation models: 1,000,000 operations min.
Alternate operation models: 100,000 operations min.
(One operation consists of set and reset operations.)
Electrical: 100,000 operations min.

Note:
1. With alternate operation models, 60 operations/minute max. One operation cycle consists of set and reset operations.
2. The figure for dielectric strength between lamp terminals is for when the LED lamp is not mounted.
3. “Malfunction” in the above table indicates malfunctions of less than 1 ms.
