Notes

Wiring

Contact protection box internal circuit

Contact protection box internal circuit

  1. * 1Do not apply pulling force to the power cord. It may cause damage.
  2. * 2Wiring precautions for ZSM1-121: When ZSM1-121 is connected in series, a voltage drop occurs due to the internal resistance of the light emitting diode. The voltage drop is approx. 2 V per switch. After checking the minimum drive voltage on the drive side, use within the range possible.
  3. * 3Since it does not have a built-in contact protection circuit, use the contact protection box (CD-P11) with an inductive load or a lead wire of 5 m or longer.
  4. * 4Contact protection box / connection method: To connect the switch body to the contact protection box, connect the lead wire on the side labeled SWITCH on the contact protection box and the lead wire from the switch body. Also, keep the lead wire length between the switch body and the contact protection box within 1 m, and set it as close as possible.

Mounting/Piping

The main body must not be turned with a wrench

The main body must not be turned with a wrench

  1. * 1When handling the product, always hold it by the body and do not apply pulling force to the power cord.
  2. * 2When handling, do not drop or hit. It may cause damage.
  3. * 3When mounting on the pipe, apply a wrench to the fitting and screw in. Turning the main body with a wrench may cause damage.
  4. * 4The mounting direction can be horizontal or vertical.

Pressure source

  1. * 1When used as a suction confirmation switch, do not suck in water. It may cause malfunction or damage
  2. * 2Operating fluids are dedicated for air and inert gas. Corrosive fluid cannot be used.
  • *See the SMC catalog for information other than that detailed above.
