BCGOH38B Semi-Hollow Shaft Incremental Rotary Encoder Ø38mm

What makes the BCGOH38B incremental rotary encoder different?

The BCGOH38B features a compact 38mm magnetic or photoelectric sensing design with a semi-hollow shaft, available in Ø8mm standard and Ø6mm optional configurations. Its side cable outlet with a metal protective sleeve provides flexible installation, while multiple resolution and output options make it suitable for industrial position and speed measurement applications.

What are the main specifications of the BCGOH38B?

The BCGOH38B features a 38mm housing diameter and semi-hollow shaft design, with Ø8mm standard and Ø6mm optional shaft sizes. It supports magnetic or photoelectric sensing, side cable outlet, multiple resolutions from 10 to 10,000 PPR, five output configurations, and several incremental signal options.

Is the BCGOH38B a magnetic or photoelectric encoder?

The BCGOH38B is available in magnetic (0 code) and photoelectric (L code) versions. The operating principle is selected according to the model configuration. Both versions are designed to provide rotational position and speed feedback for industrial machinery and automation systems.

What shaft options are available?

The BCGOH38B uses a semi-hollow shaft design (H code). The standard shaft diameter is Ø8mm, with Ø6mm available as an optional configuration. Please confirm the shaft dimensions and mechanical connection requirements before ordering to ensure compatibility with your equipment.

What cable outlet options does the BCGOH38B offer?

The BCGOH38B offers two cable outlet configurations: B — Side Outlet with Metal Protective Sleeve and D — Rear Outlet with Metal Protective Sleeve. The B configuration is suitable for side cable routing, while the D configuration accommodates rear cable routing. Please confirm the required outlet direction before ordering.

What protection rating does the BCGOH38B have?

The BCGOH38B features a metal protective sleeve at the cable outlet to help protect the cable connection. Its industrial construction is designed for rotary position and speed feedback applications. The exact IP protection rating is not specified in the available product data. Please contact BOCHEN to confirm protection requirements for your application.

What resolution options are available?

Available resolutions include 10, 20, 50, 60, 100, 200, 360, 400, 500, 600, 800, 1000, 1024, 1200, 2000, 2048, 2500, 3000, 3600, 5000, and up to 10,000 PPR, depending on the selected configuration. Choose the appropriate resolution according to your speed measurement, positioning requirements, and controller specifications.

What output forms does the BCGOH38B support?

The BCGOH38B supports five output configurations: C — Open Collector Output, F — Complementary Output, T — Push-Pull Output, L — 5V Drive Output, and A — 24V Drive Output. Select the appropriate output according to your controller's electrical interface and operating requirements.

What output signals can I choose?

Available signal configurations include Phase A, Phase AB, Phase ABZ, A/A? and B/B? complementary signals, and A/A?, B/B? and Z/Z? complementary signals. These correspond to signal codes 1, 2, 3, 4, and 6 respectively. Select the signal configuration according to your measurement and control requirements, ensuring compatibility with your receiving device.

Can the BCGOH38B provide both pulse and analog outputs?

The BCGOH38B is an incremental pulse encoder supporting A, AB, ABZ, and complementary signal configurations. Analog output options such as 4–20mA, 0–5V, and 0–10V are not listed in its standard specifications. Please select the appropriate pulse output configuration for your control system.

What is the standard cable length?

The standard cable length is 2 meters. Other cable lengths are available upon request. Please specify your required cable length when requesting a quotation or placing an order.

Is the BCGOH38B suitable for industrial automation equipment?

Yes. Its 38mm housing, semi-hollow shaft design, and flexible output configurations make it suitable for industrial equipment requiring reliable rotational feedback. Typical applications include textile machinery, CNC machines, motor speed control, warehousing and conveyor systems, packaging machinery, printing machinery, glass industry equipment, elevators, and industrial automation systems.

Can the BCGOH38B replace a 40mm rotary encoder?

The BCGOH38B has a 38mm housing diameter, while a 40mm encoder has a different nominal housing size. They should not be considered direct replacements without checking mechanical dimensions, mounting positions, shaft diameter, electrical connections, resolution, and output signals. BOCHEN can help evaluate compatibility based on your existing encoder model or technical drawing.

Can BOCHEN provide samples for testing?

Yes. Samples can be discussed for customers who need to evaluate mechanical installation, electrical connections, signal output, and equipment compatibility before bulk purchasing. Please contact our sales team with your required specifications.

Does BOCHEN support OEM/ODM and customized orders?

Yes. BOCHEN supports OEM/ODM projects, specification customization, and factory-direct supply. Customers can select the operating principle, shaft diameter, resolution, output form, output signal, cable outlet direction, and cable length according to their application requirements.

Can I place a small-batch order?

Yes. BOCHEN supports small-batch orders and bulk production. Order quantities and lead times depend on the selected configuration and production requirements. Contact our team to discuss your project.

Which countries does BOCHEN serve?

BOCHEN supplies industrial components to customers in 150+ countries worldwide, serving distributors, OEMs, equipment manufacturers, and industrial automation customers.

What information should I provide when requesting a quotation?

Please provide your existing encoder model, operating principle, shaft diameter, required resolution (PPR), output form, output signal, cable outlet direction, cable length, and order quantity. A datasheet, product photo, or equipment drawing can also help our engineers recommend a suitable configuration.
