Limit switch



HS1 en hinban


・Contactless circuit

  Suoerior reliability and long functional life compared to mechanical contact switches, durable more than 20 million operations.

・Shielded structure

  Immune to hostile environments, available under such conditions as pouring water/oil.

・Stable operation

  Because such parts susceptible to common troubles as hinges and sliding parts, are not exposed, stable operation can be assured.

・High sensibility

  The accuracy of the repeatability of operating points is ±0.02mm.
