WARNING

PERSONAL INJURY

•  Where possible, install these switches with the conduit 

opening pointed down to drain moisture away from switch.

•  Do not install switch at the low point of a conduit run.
•  Install a fitting into the conduit opening that provides 

strain relief to the wires/cable, as well as sealing against 
contaminants found in the application.

•  In applications where fluids or moisture may be present, 

seal the fitting threads with a product such as Teflon tape 
or pipe dope.

Failure to comply with these instructions could result in 
death or serious injury.

4.  Position the large diameter end of the actuator spring 

over the actuator. Place retaining screws through gasket 
material and position head over screw holes in desired 
position.

5.  Securely tighten the screws to 0,2 N m [1.7 in lb] of torque.

POSITIONING LEVER

The lever on rotary actuated units is adjustable to any of the 
segmented positions 360° around the shaft; however, the 
degree of rotation is dependant on head position and direction 
of roller.

1.  Loosen the lever retaining screw with a Phillips head 

screwdriver.

2.  Remove lever.
3.  Reposition lever to desired location.

1.  Loosen the lever’s adjustment screw using a Phillips head 

screwdriver.

2.  Adjust to desired length.
3.  Securely tighten adjustment screw to 1.0 N m [8.85 in lb] of 

torque.

OP ROLLER PLUNGER

Switches with top roller plunger must be mounted with plunger 
in desired position. Actuating device must not exceed over 
travel distance. 

WIRING

2.  Contact block area by terminal screw is labeled for NO 

(Normally Open) and NC (Normally Closed) contacts.

3.  Connect stranded wire (0,75 mm² - 2,5 mm², 18 AWG-14 

AWG) or solid wire (0,75 mm² - 1,5 mm², 18 AWG-16 AWG) 
to desired connector terminals. Use 90 °C [194 °F] rated 
wire when ambient temperature is to exceed 75 °C [158 °F]:

 

• 

Torque switch terminal screws to  0,8 N m to 1,0 N m  

 

[7.1 in lb to 8.9 in lb]

4.  Securely tighten cover screw to 0,5 N m [4.4 in lb] of torque.
