High quality brand new elevator controller elevator door micro switch wholesale price elevator accessories micro switch travel switch limit switch Z15G-03B

Contact configuration: 1 NO/1 NC (i.e., one normally open contact and one normally closed contact), contact material: silver alloy, SPDT (single-pole, double-throw) type.
Electrical parameters: Insulation resistance: 100 MΩ at 500 VDC, maximum contact resistance: 50 mΩ, dielectric strength: 2000 VAC for 1 minute. Rated voltage: 15 A (10 A) for non-inductive loads and 1.5 A for inductive loads at 125 VAC; 15 A (10 A) for non-inductive loads and 1.25 A for inductive loads at 250 VAC.
Mechanical parameters: Plastic (phenolic) housing, dimensions: 49.2 mm × 24.2 mm × 17.45 mm. Vibration resistance: 10-55 Hz (1.5 mm amplitude), maximum shock resistance: 100 g (maximum 30 g for malfunction). The operating temperature range is -25°C to +80°C, the storage temperature is -30°C to +80°C, and the humidity is 35%-85% RH (at -5°C to +40°C). The operating speed is 0.1mm/s to 0.5m/s, with a maximum electrical operating frequency of 20 cycles/minute and a maximum mechanical operating frequency of 240 cycles/minute. The mechanical lifespan is at least 20 million cycles, and the electrical lifespan is at least 500,000 cycles.

Load Matching: Do not exceed the rated electrical parameters (e.g., maximum 15A non-inductive load at 250VAC). If controlling high-power devices (e.g., motors over 5kW), use a contactor to prevent burnout of the switch contacts due to overload.

Regular Maintenance: Check every 3-6 months:

Contacts for signs of burnout (if contact resistance is excessive, the switch should be replaced);

Button tips for wear (wear may cause insensitive triggering);

Loose terminals for loose connections (loose connections may cause poor contact and equipment malfunction).

Safety Protection: If used in high-voltage circuits (e.g., 380V motor control), a fuse or circuit breaker must be connected in series with the switch to prevent short-circuit hazards.
