Description
The NEMICON HES Series are high-quality Japanese-made incremental rotary encoders designed for precise position and speed feedback in servo systems, CNC machines, robotics, and industrial automation. Models such as HES-0512-2MHC, HES-06-2MHC, HES-06-2MHT, and HES-06-2MD feature a compact 50mm or 38mm housing with hollow shaft (through-hole) or solid shaft options, 512 to 2500 PPR resolution, and differential line driver (or open collector) outputs compatible with major servo drives and PLC high-speed counters.
Key Features
- Resolution Options: 100 to 2500 PPR (HES-0512 = 512 PPR standard)
- Shaft Type: Hollow shaft (through-bore) or solid shaft — HES-06 typically ø6mm solid shaft; HES-05xx = ø8mm hollow or solid per sub-code
- Output Circuit: Line Driver (26C31 / AM26LS31, differential RS-422) or Open Collector (OC) — “2MHC/2MHT” usually = Line Driver, “2MD” = Open Collector NPN/PNP
- Supply Voltage: 5V DC (Line Driver) or 5-12V/24V DC (OC versions — confirm by suffix)
- Protection: IP50–IP65 (depending on cable/outlet option)
- Connector / Cable: Radial or axial cable outlet (M12 or pre-wired)
- Country of Origin: Japan (NEMICON / Nemicon = brand of Japan)
