AutomationDirect TRD-GK500-RZD JTEKT Incremental Encoder | 500 PPR | 10-30V DC

Description

The AutomationDirect TRD-GK500-RZD is a heavy-duty incremental (quadrature) rotary encoder in the JTEKT TRD-GK series, manufactured by JTEKT Electronics (formerly Koyo Electronics). It is compatible with motion control systems, PLCs, and servo/stepper drive platforms that accept push-pull quadrature encoder response.

This encoder delivers 500 pulses per revolution via a push-pull (totem pole) output with 3 channels: quadrature A and B outputs 90 degrees out of phase, plus a home/Z index pulse. It operates on 10–30V DC (nominal range 9.7–30.9 VDC) and draws 50 mA max below 16V DC or 70 mA max at 16V DC and above. Output signals have a 2µs max rise/fall time and a maximum response frequency of 100 kHz, yielding a maximum allowable shaft speed of 12,000 RPM at this resolution. The 10mm solid shaft exits axially with an integral 2-meter (6.5 ft) pigtail cable.

The TRD-GK500-RZD features a 78mm diameter body and an IP65 ingress protection rating, providing protection against dust contact and low-pressure water jets from any direction. Mounting brackets for the TRD-GK series are available separately from AutomationDirect. Refer to manufacturer documentation to confirm compatibility with your specific application.

About ACME MRO Solutions

We started ACME MRO Solutions to fix something we kept running into as contractors — plants down, parts slow, surplus listings you couldn't trust. Our goal is simple: get YOU the right component fast, with an honest description, so you can get back to running.

We describe what we see. Used items show signs of use; if a part has visible wear, damage, or a missing component, the condition description will say so. We don't claim anything is tested unless we tested it — and we don't bench-test parts where testing isn't practical or revealing (feed-through modules, breakers, mechanical components). When we do test something, we'll say so explicitly.

If something is our fault, we don't work through it — we make it right. We are proud to serve American manufacturing. Your uptime is our bottom line.
