tive and low-temperature models.)

Lead wires are attached.

The case cover and conduit section are

molded from epoxy resin to improve seal-

(See

note 3.)

WLj-140

WLj-141

Lead wires are attached.

The case is filled with epoxy resin, to en-

sure high sealing performance.

The Head opening is protected from cut-

ting powder. (WLj-141)

Only WLG2, WLCA2, and WLGCA2 can

be fabricated. (WLj-141 models.)

Anti-

coolant

WLj-RP60

Lead wires are attached.

The case is filled with epoxy resin, to en-

sure high sealing performance. To im-

prove the anti-coolant properties (water-

soluble coolant), rubber with high chemi-

cal-resistance has been used.

Spatter-preven-

tion

WLj-S

Yes

To improve spatter prevention during

welding, a heat-resistant resin is used,

and screws and rollers are all made from

stainless steel.

Heat-resistive

WLj-TH

Yes (Cannot be used with airtight, her-

metic, low-temperature, corrosion-

proof, or lamp-equipped models.)

To improve heat resistance, silicone rub-

ber is used for rubber parts and for the

built-in switch.

The operating temperature range is +5_C

to 120_C.

29

Low-temperature

WLj-TC

Yes (Cannot be used with airtight, her-

metic, heat-resistive, corrosion-proof,

or lamp-equipped models.)

To improve low temperature resistance,

silicone rubber is used.

The operating temperature range is

--40_Cto40_C.

Corrosion-proof

(See note 4.)

WLj-RP

Yes (Cannot be used with lamp-

equipped models.)

Diecast parts such as the switch box are

made of corrosion-proof aluminum. Rub-

ber-sealing parts are made of fluorine

rubber and exposed nuts and screws are

made of stainless steel. These all aid in

resisting oil, chemicals and adverse

weather conditions.

(See note

Yes

(See note

6.)

---

Rotary shafts are made of unquenched

(i.e., untreated) stainless steel to improve

corrosion resistance. Exposed nuts and

screws are made of stainless steel and

rubber sealing parts of silicone rubber.

These factors all combine to create a

product which is resistant to temperature

changes and adverse weather condi-

tions.

Lamp-equipped

Possible to set to one-side operation on either side.

Pretravel (PT) is 5_.

3. When ordering, add the suffix for the environment-resistant model or indicator specifications required according to the operating

environment and purpose.
