NICE / APOLLO A2072, SMART SPEED SENSOR, INDUCTIVE, 8'' LEAD FOR 816 ACTUATOR
The Nice Apollo A2072 is a smart speed sensor used on compatible Apollo actuator assemblies, commonly referenced for 416 and 816 style actuators and also described in some listings for 816 / 816X arms. The speed sensor provides movement feedback so the control system can monitor actuator travel more accurately. If this sensor or its lead is damaged, the operator may show abnormal movement behavior, inconsistent slow-down, control faults, or symptoms that look like a limit or board problem. A2072 is not the same part as a magnetic limit switch and should not be ordered solely because the gate fails to stop at the correct position. Before replacing it, check the actuator model, sensor location, lead length, connector, board diagnostics, and whether the harness or limit assembly has also been damaged.
Compatible With
- Nice Apollo 416 actuator applications where A2072 is specified
- Nice Apollo 416X actuator applications when the SMART sensor setup matches
- Nice Apollo 816 actuator applications where A2072 is specified
- Nice Apollo 816X actuator applications when the SMART sensor setup matches
- Apollo 1500 / 1550 / 1600 / 1650 family systems using compatible 416 or 816 actuator arms
- Verify by parts diagram for SMART sensor and lead configuration

Technician Note
For Apollo actuator parts, do not order by appearance only. Small differences in actuator generation, cable length, SMART feedback, limit style, connector layout, or internal hardware can make similar parts non-interchangeable. Compare the original part number, actuator model label, and exploded parts diagram before replacing the component.
Before Ordering Checklist
- Confirm the actuator model and operator series on the installed gate system.
- Match the original part number or the manufacturer parts diagram whenever possible.
- Check whether the repair involves a standard 816 actuator, 816X SMART actuator, 416 actuator, or another Apollo arm.
- Inspect related wear parts before replacing only one component.
- For electrical parts, disconnect power and have unsafe wiring or high-current diagnosis handled by a qualified gate technician.
Professional Advisory
Gate actuators are moving mechanical assemblies tied to control-board logic and required safety devices. After replacing internal actuator, harness, motor, sensor, or limit parts, the gate should be tested through full open and close cycles with proper force settings, limit settings, entrapment protection, and safety accessories in place. Do not bypass safety devices to make a repaired gate run.
Product Questions & Answers
Is A2072 a limit switch?
No. A2072 is a smart speed sensor. Apollo magnetic limit switches, limit blocks, and complete limit assemblies are separate parts.
What symptoms can a failed speed sensor cause?
A failed or damaged sensor can contribute to movement feedback faults, abnormal slow-down behavior, inconsistent operation, or diagnostic issues depending on the control board.
Is it compatible with both 416 and 816 actuators?
Common references list A2072 for 416 or 816 actuators, and some also mention 816 / 816X arms. Verify the exact actuator generation before ordering.
Can a harness problem look like a sensor problem?
Yes. Damaged wiring, bad connectors, water intrusion, or a control board issue can mimic a sensor failure.
What should be inspected before replacing A2072?
Inspect the sensor body, lead, connector, actuator harness, control board input, and whether the actuator has mechanical drag or internal damage.
