MICRONOR Offers MR221/MR222 Series UL/cUL-Approved Geared Limit Switches

The MR22X series is often used as either a primary control or back-up safety device to the equipment under control. The standard units feature a heavy duty ½” (12.7mm) OD stainless steel shaft (with #404 Woodruff keys provided) and heavy duty, sealed bearings. The individual cam switch channels (from 2 to 8) are independently programmable over 4-356; while the heavy duty sealed switches (rated 6A-continuous/10A-momentary) offers both NO/NC contacts and field replaceable. COMBICON screw-down wiring blocks provide for ease of hook-up. A cam programming tool (stored internally), Woodruff keys and two built-in ½” NPT conduit hubs/plugs are supplied with each unit.

Product options include: single- (MR221) or dual-ended (MR222) shafts, step-up or step-down gear ratios; and NEMA 6/6X / IP66 rated powder-coated die cast aluminum or stainless steel enclosures. The MR22X series meet UL 508 performance and safety requirements.

Micronor also specializes in custom engineered configurations including application-specific housings as well as integration with other feedback/position sensors (i.e. optical encoders, fiber optic encoders, resolvers, tachometers, potentiometers, selsyns and 4-20mA outputs). For the past 40 years, Micronor has been a demonstrated leader in custom engineered feedback transducers as well as replacements for obsolete and out-of-production position feedback units (by Baumer, BVR, Crouzet, Eucron, Micron, etc.).

Offering a wide range of configuration options, the Micronor standard MR22X series are built-to-order with typical 2-3 week lead times. A typical MR221 unit housed in aluminum housing with 4 cam switch channels and 100:1 gear ratio - is $999 each in small quantities.
