High-level accuracy gives firm detection for position
fixing, etc., by using perpendicular movement.
Operating range can be widened by mounting
accessory actuators like cams, dogs, cylinders, etc.
High-level detection for position fixing.
The stroke in the direction of revolution is large at
between 45° and 90° and the lever angle can be set
at will to within 360° for easy use. Wide angle type
(large O.T.) available. Can be used for wide-range
position fixing.
Lever length can be altered to allow rough operation
detection using the roller lever characteristics.
Wide range of operations, and convenient for
uneven mountings. Lightest operation among the
revolving operation type of limit switches. Rod length
is adjustable, and bending is also easy.
If operated up to 55° position, revolves automatically
to retain 90° position. Two dog operation enables
recovery operation through single dog, or for any-
thing that has caused the roller position to slip.
Excluding the thread direction, direction can be
adjusted up to 360°. Operating power is the lowest
of the limit switches, and is effective in detecting
when direction and conditions are uneven. In order
to absorb the movements after operation in the actu-
ator part, work slippage tolerances are also large.
Using a low speed, low torque cam, the lever can
assume various shapes suited to the operation. The
lever is very sturdy.
Suited to high speed cams through the attachment
of a hinge roller lever.
Operation is possible with both hinge lever type and
one way operation, but the roller will break if operat-
ed in the opposite direction, rendering the unit inop-
erable. Can be used to prevent opposite direction
movement.
The roller position can be changed.
