Oscar Rotary limit switches

Features

• It 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.
• Accurate adjustment of cams by means of screws.
• Positive opening NC contacts for safety functions.
• Mechanical life of switches: up to 10 million operations.
• IP protection degree: Oscar is classified IP 65 / IP 66 / IP 67 / IP 69K.
• NEMA protection degree: Oscar is classified Type 4X (cULus marked versions).
• Extreme temperature resistance: -53°C to +80°C.
• 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.

Options

• Revolution ratios from 1:1 to 1:1550, 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 3 switches), Egon 36-AL absolute 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 4 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), Egon 36-AL absolute encoders (alone or on top of cam sets with up to 4 switches) and Yankee absolute encoders (on top of cam sets with up to 6 switches).
• Dedicated cable glands 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 equipments 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 equipments 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.
• 8 PIN (4 for each sensor).

Certifications

• CE marking, cULus* marking.
• Complying with accident prevention regulation BGV C 1 (only for Germany).
• HALT TEST (Highly Accelerated Life Test) passed, simulating.

* Not available on all versions.
