These are motion handwheels with a gravity or fixed reaction indicator included, to measure adjustments (angles, shiftings, speed, etc.) on a control dial with graduated circular scale.
The dials measure is given by the two pointers: the red pointer carries out a complete turn at every rotation of the drive shaft, and at the same time, the black pointer makes a rotation fraction. The turns that the black pointer needs to carry out to complete a rotation is the ratio of the indicator.
• Reinforced technopolymer handwheel, transparent polycarbonate cover. Protection IP65. Max. temperature 80°C.
• IP50 and IP80 (gravity reaction) are suitable for horizontal or slightly inclined shafts.
• IF50 and IF80 (fixed reaction) are mounted on shafts with any position.
• The lock pin for the fixed reaction is in zinc-plated steel ø3 mm or threaded M3 (on request).
• Hub with aluminium bushing with bored holes ø8 or ø10 mm, and transversal screw M5 for the fixing to the shaft.
