selection: basic, split contact, maintained contact,

and adjustable contact gap types.

A series of standard models for minute loads is

available.

A series of molded terminal-type models incorpo-

rating safety terminal protection cover is available.

Including models that meet the quality require-

ments of the RCJ under license number RCJ-17-4.

Ordering Information

Configuration

Basic Models

General-purpose

A variety of actuators is available for a wide range of application.

The contact mechanism of models for minute loads is a crossbar

type with gold-alloy contacts, which ensures highly reliable opera-

tions for minute loads.

Contact Gap:

H: 0.25 mm (high-sensitivity, microvoltage current load)

G: 0.5 mm (standard)]

E: 1.8 mm (high-capacity)

Contact Form

Movable contact

that the switch is resistant to humidity, oil, and dust. The degree of

protection conforms to JIS C0920 drip-proof II.

The electric insulation of the molded terminals is ensured because

the terminal part is fixed with epoxy resin. The actuator and termi-

nals are both sealed and thus resist water, oil, or dust. The lead

wires can be stretched in either direction. Refer to page 43 for de-

tails.

Note:

The Z-15GM is a reversible model and the NO and

NC positions are reversed.

Drip-proof Models

There is no difference in basic configuration and switching mecha-

nism between drip-proof models and standard models, and a vari-

ety of actuators can be used with drip-proof models. Drip-proof

models use weather-resistive chloroprene rubber.

Without Terminal Cover

The pin plunger is sealed from the other switch mechanisms by a

resilient rubber, and the case and cover are sealed by adhesive so

With Terminal Cover

The high sealing capability (drip-proof) and the terminal protection

allows switching operations under poor environment with water and

dust, like limit switches. Furthermore, these switches are inexpen-

sive.

The easy-to-remove terminal protection cover allows the easy

maintenance of the wires.

By changing the terminal protection cover position, the cable can be

stretched in the left or right direction.

The width of this model is the same as that of the conventional Z

model. Therefore this model can be mounted under the same condi-

tions.
