For the toughest environments, call on NorthStar heavy-duty encoders. Formerly known as Lakeshore Encoders, NorthStar manufactures innovative and reliable products for measuring speed and position in extreme manufacturing environments.
These heavy-duty, mill-duty magneto-resistive incremental encoders; compact and washdown resistant, harsh-duty optical incremental encoders; and pulse tachs are designed to provide rugged, high-performance signals in the harshest situations.
NorthStar Encoder Overview
Industry Applications
Steel Mills - RIM Tach® 8500 NexGen Encoder
Compact and bearingless, the RIM8500 NexGen mounts to any 180 C Face motor. The Stainless steel and cast iron construction make it a perfect fit for the harsh conditions in a steel mill. Sensor modules are removable on the fly allowing for quick replacement and require no gapping.

NexGen RIM Tach RT8
NexGen 8.5″ 180 C-Face motor tach is easy to install with wider air gap, high power line driver and improved wheel design. Up to 2,400 PPR.

NexGen RIM Tach RT6
NexGen 56 C-Face or foot mount shafted encoder with wider air gap, built in diagnostic LED and high-power line driver. Up to 2,400 PPR.

NexGen RIM Tach RT1
NexGen 12.5″ 250 C-Face mount motor tach with wide air gap for easy installation, high power line driver and ESD protection. Up to 2,400 PPR.

HT55 Large Bore Magnetic Encoder
Hollow-shaft magnetic encoder with max bore size 2.875″. Designed for easy installation with tough construction. Resolution up to 4,096 PPR.

HT85 Large Bore Magnetic Encoder
Hollow-shaft magnetic encoder with max bore size 4.5″. Designed for easy mounting and to survive tough environments. Resolution up to 2,400 PPR.
Oil & Gas - HSD37 Harsh Duty Optical Encoder
For the corrosive oil and gas environment, our encoders offer to oilfield equipment manufacturers and end users enhanced sealing, industry certifications and an overall improved solution.
Reliable Encoders for the Oil and Gas Industry
Certified Encoders For Oil & Gas
As one of the most potentially volatile industries, the oil & gas industry requires reliable encoders that meet industry standards.
With ATEX Zone 0 and Zone 1, NEC Class I Div II, CE and CSA certifications, Dynapar’s NorthStar encoders offer advanced sensing technology and reliable solutions for Oil & Gas. Certified for use at -50• to 100• C, they are independently tested at up to 400G shock and 20G vibration. These unique encoders provide reliable output signal up to 1000 feet with high current driver and offer the industry’s toughest optical engine with unbreakable disc.
For the corrosive oil and gas environment, our encoders offer to oilfield equipment manufacturers and end users enhanced sealing, industry certifications and an overall improved solution. They are used in drill motors, top drives, rotary tables, mud pumps, pipe handling, production equipment and more.
Recommended Solutions

DWD38 – Drawworks Applications
The DWD38 encoder is designed exclusively for drawworks applications on an oil rig. The NorthStar DWD38 is certified as an ATEX Zone 0 Intrinsically Safe encoder. The DWD38 has a temperature range of -40 to 100°C with a 400g shock rating making it ideal for the tough environment of the oil rig.

EN42 – Drilling Motor Applications
The EN42 is ATEX certified for use in Zone 1 on the oil rig. A barrier is normally required for a Zone 1 application which can add additional cost to the solution. The EN42 encapsulated electronics eliminate the need for a barrier and with an industry leading -50 to 100°C temperature range, it is ideal for Zone 1

EN44 – Drilling Motor Applications
The EN44 is ATEX certified for use in Zone 1 on the oil rig. A barrier is normally required for a Zone 1 application which can add additional cost to the solution. The EN44 isolated coupling compensates for motor shaft run out and endplay and the encapsulated electronics remove the need for a barrier.
