Rotary limit switch 'OSCAR': reliable & flexible, configured with gear ratio 1 : 50 and a second output ratio 1 : 1 and 4 switches. Protection class: IP67/IP69K
- Controlling/measuring the movement of industrial machines
- Controlling/measuring or the position of the nacelle or pitch angle of wind turbines.
The OSCAR limit switch offers the flexibility of 2 different outputs with different revolution ratios and the possibility of installing different movement detection devices.
Features OSCAR rotary limit switch
- The OSCAR rotary limit switch consists of a gear motor that transfers movement to the cams and the other movement detection devices through a primary input reduction stage (worm gear and helical toothed gear) and one or more secondary output stages.
- Cams can be accurately adjusted by means of screws.
- Positive opening NC contacts for safety functions.
- Mechanical life switches: up to 10 million operations.
- OSCAR rotary limit switches are classified IP66, IP67 and IP69K.
- NEMA protection degree: Oscar is classified Type 4X*.
- Extreme temperature resistance: -53℃ to +80℃.
- It features transmission and gear driving shafts made of stainless steel AISI 430F or AISI 303, worm gear transmission shaft rotating on ball bearings, self-lubricating technopolymer gears and driving bushes, technopolymer base and cover.
- All materials and components used are wear resistant and guarantee protection of the unit against water and dust.

!! The OSCAR models in our webshop are standard models with revolution ratios between 1:1 and 1:1550. Are you in need of a customized FOX limit switch? Please, contact one of our sales engineers !!
- Revolution ratios for our webshop models from 1:1 to 1:450, achieved by combining different secondary output stages.
- Each of the two outputs can be set to a different revolution ratio to enable diversified control of the machine when special requirements need to be met.
- Snap action switches with 1NO+1NC change-over contacts or slow action switches with 1 NC contact.
- It can be equipped with 2 cam sets (with up to 10 switches), potentiometers and encoders (alone or on top of cam sets with up to 2 switches) and Yankee absolute encoders (on top of cam sets with up to 3 switches).
- XL version featuring cover rise available with 2 cam sets (with up to 12 switches), potentiometers and encoders (alone or on top of cam sets with up to 5 switches) and Yankee absolute encoders (on top of cam sets with up to 6 switches).
- Dedicated cable clamps or connectors.
- Available with anti-moisture plug fitted to the base by means of a lock nut, to improve transpiration for the limit switch whilst maintaining protection against water
- Available with flanges, pinions and couplings.
- Plates with universal adapter to replace existing systems.
Increased safety system “Lima”
- Lima is designed to be integrated in equipment complying with the standard ISO 13849 on control system safety rules.
- Lima can be connected to a control unit or to a PLC to control the rotation of the limit switch shaft (and thus of the equipment connected to it).
- Lima has two separate detection systems, without direct contact, using different technologies to ensure control redundancy.
- Lima allows two detection systems to be wired by using two separate cables, through a 8-pin terminal board.
- Sensor connection: self-lifting screw terminal board
- 8 PIN (4 for each sensor).
