Wiring
Circuit Connection Example
• Direct opening contacts used for safety circuit inputs are indicated
with the
mark. Terminals 12-41 and terminals 22-51 have direct
opening contacts.
• Connect the indicators in parallel to the auxiliary circuits or
terminals E1 and E2. Do not connect the indicators in parallel with
the direct opening contact. If the indicators are broken, a short-
circuit current may flow, causing equipment to malfunction.
• Do not switch circuits for two or more standard loads at the same
time. Doing so may adversely affect insulation performance.
• The 24-VDC solenoid terminals have polarity (E1: +, E2:
−
).
Confirm the polarity before wiring.
• The contact ON/OFF timing for Switches is not synchronized.
Confirm performance before application.
Wiring
• Do not wire the Switch while power is being supplied. Doing so may
result in electric shock.
• Do not let particles, such as small pieces of lead wire, enter the
switch body when wiring.
• Make sure that the wiring does not hide the LED indicator when
wiring E1/E2 or 01/02.
• When connecting to the terminals via insulating tube and M3.5
crimp terminals, arrange the crimp terminals so that they do not
rise up onto the case or the cover.
• Applicable lead wire size: AWG22 to AWG18 (0.3 to 0.75 mm
2
).
Use lead wires of an appropriate length. Not doing so may result in
excess length causing the cover to rise and not fit properly.
• Do not pull on the lead wires with excessive force. Doing so may
disconnect them.
• Do not push crimp terminals into gaps in the case interior. Doing so
may cause damage or deformation of the case.
Recommended Crimp Terminals
Processing the Conduit Opening
• Connect a recommended connector to the opening of the conduit
and tighten the connector to the proper torque. The case may be
damaged if excessive tightening torque is applied.
• When using a 1/2-14NPT conduit, wind sealing tape around the
conduit end of the connector so that the enclosure will conform to
IP67.
• Make sure that the outer diameter of the cable connected to the
connector is correct.
• Attach a conduit cap to the unused conduit opening when wiring
and tighten it to a suitable torque. The conduit cap is provided with
the Switch.
Recommended Connectors
Use a connector with a screw section not exceeding 9 mm.
Otherwise, the screws will protrude into the case interior. The
connectors given in the following table have connectors with screw
sections not exceeding 9 mm. Use the following connectors to
ensure conformance to IP67.
Use LAPP connectors together with Seal Packing (JPK-16, GP-13.5,
or GPM20), and tighten to the applicable torque. Seal Packing is sold
separately.

• For a 1/2-14NPT conduit, use the above connector after attaching
the provided Adaptor to the Switch and wrapping it with sealing
tape.
Operating Environment
• The Switch is intended for indoor use only.
Do not use the Switch outdoors. Doing so may cause the Switch to
malfunction.
• Do not use the Switch where corrosive gases (e.g., H
2
S, SO
2
, NH
3
,
HNO
3
, or Cl
2
) are present or in locations subject to high
temperature and humidity. Doing so may result in damage to the
Switch caused by contact failure or corrosion.
• Do not use the Switch in the following locations.
• Locations subject to severe temperature changes.
• Locations subject to high humidity or condensation.
• Locations subject to severe vibration.
• Locations where the interior of the Protective Door may come
into direct contact with cutting chips, metal filings, oil, or
chemicals.
• Locations where the Switch may come into contact with thinner
or detergents.
• Locations where explosive or flammable gases are present.
Maintenance and Repairs
The user must not maintain or repair equipment incorporating the
Switch. Contact the manufacturer of the equipment for any
maintenance or repairs required.
Storage
Do not store the Switch where corrosive gases (e.g., H
2
S, SO
2
, NH
3
,
HNO
3
, or Cl
2
) or dust is present, or in locations subject to high
temperature or high humidity.
