HySecurity MX000091-P*, KIT, IES SENSOR REPLACEMENT
The HySecurity MX000091-P is a replacement IES sensor kit for select HySecurity and Nice HySecurity gate operator systems. It is commonly listed as KIT, IES SENSOR REPLACEMENT and is closely related to the HySecurity MX000091 Inherent Entrapment Sensor switch kit reference.
IES stands for Inherent Entrapment Sensor. In compatible HySecurity hydraulic gate operators, this sensor is part of the built-in entrapment protection system. It helps monitor hydraulic load or resistance conditions so the operator can respond when abnormal resistance is detected during gate travel.
Related MX000091 listings describe the part as an Inherent Entrapment Sensor switch kit with sensor and fittings. Current MX000091-P listings describe the kit as an IES sensor replacement kit and may reference an adaptive sensor, switch, installation fittings, and thread sealant. Because package contents can vary by supplier and revision, verify current kit contents before publishing those items as guaranteed.
What This IES Sensor Kit Does
The MX000091-P IES sensor kit helps restore the inherent entrapment sensing function on compatible HySecurity operators where this replacement kit is specified. The sensor works with the operators hydraulic circuit and control system to help detect abnormal force or resistance during movement.
If the IES sensor is damaged, leaking, miswired, incorrectly installed, contaminated, or not properly recognized by the controller, the operator may show IES-related faults, nuisance trip, stop unexpectedly, reverse during travel, fail to complete a run cycle, or refuse to operate normally. Similar symptoms can also be caused by a dragging gate, bad wheels or hinges, hydraulic pressure problems, low fluid, valve issues, faulty wiring, incorrect force settings, poor alignment, or a controller issue.
Compatible With
The HySecurity MX000091-P is intended for select HySecurity / Nice HySecurity operators where the IES sensor replacement kit is specified. Compatibility depends on the operator model, sensor generation, hydraulic system, controller platform, wiring, fittings, and current HySecurity parts documentation.

- Thread sealant: May be listed with some current kit descriptions, but package contents should be verified before publishing as included.
The asterisk sometimes shown after MX000091-P appears to be a supplier or catalog flag. It should not be used in the clean customer-facing URL, and it should only remain in your internal SKU if your inventory system requires it.
Inherent Entrapment Protection Note
The IES sensor is part of the operators safety system. It should not be bypassed, removed, plugged, or defeated to make the gate run. If an operator is nuisance tripping, the cause should be diagnosed instead of disabling the protection.
IES trips can be caused by sensor problems, but they can also be caused by real gate resistance. Before replacing the sensor, inspect the gate mechanically and hydraulically. A dragging slide gate, worn rollers, bad V-track, tight swing gate hinges, low hydraulic fluid, improper pressure, or binding hardware can all cause abnormal resistance.
Related Parts and Service Items
IES sensor troubleshooting should be handled as part of the full hydraulic and safety system. A false trip or IES fault may involve more than the sensor itself.
- HySecurity hydraulic pressure gauge kits where hydraulic pressure needs to be checked
- HySecurity relief valves where pressure control is being diagnosed
- HySecurity hydraulic hose kits and quick disconnect fittings where leaks or restrictions are present
- HySecurity pump packs where hydraulic output is weak or unstable
- HySecurity controller boards where sensor input or fault processing is being diagnosed
- Gate wheels, rollers, hinges, track, posts, brackets, and alignment hardware where mechanical resistance is present
- Monitored photo eyes, safety edges, and other required entrapment protection devices used with the operator
Not Intended For
- Universal pressure sensor replacement
- Bypassing or disabling inherent entrapment protection
- Replacing monitored external safety devices such as photo eyes or safety edges
- Replacing controller boards, hydraulic pump packs, valves, hoses, cylinders, or gate hardware unless those parts are separately ordered
- Correcting IES trips caused by a dragging gate, bad wheels, bad hinges, low fluid, pressure problems, or mechanical binding without diagnosis
- Installing into a non-compatible operator where the parts diagram does not call for MX000091-P or the related MX000091 IES kit
Important Compatibility Warning
MX000091-P should be selected by HySecurity part number, operator model, sensor style, hydraulic fitting requirement, wiring, controller generation, and parts diagram. A sensor that appears similar may not have the same pressure response, fitting style, wiring connection, or controller compatibility.
If the operator is faulting on IES, inspect the gate and hydraulic system before replacing parts. A new sensor will not correct a gate that is physically binding, dragging, over-pressurized, low on fluid, or mechanically misaligned.

Technician Note
Before replacing the IES sensor, check the gate for real resistance. On a slide gate, inspect the wheels, V-track, guide rollers, chain path, drive rail, gate stops, and gate alignment. On a swing gate, inspect hinges, actuator geometry, cylinder movement, pins, bearings, and gate balance. A gate that is dragging or binding can trip IES even when the sensor is working correctly.
If the sensor is replaced, inspect the hydraulic fitting connection, wiring, controller input, and fault history. The IES system is safety-related, so the operator should be fully tested after repair.
Before Ordering, Confirm

- Confirm the sensor style, fittings, wiring, and controller generation match the installed operator.
- Confirm the operator is not tripping IES because of real gate resistance, low fluid, pressure problems, mechanical binding, or improper setup.
- Confirm whether sensor, switch, fittings, thread sealant, wiring, labels, or instructions are included or must be ordered separately.
Installation and Service Notes
Disable the operator and secure the gate before servicing the IES sensor or related hydraulic fittings. Do not remove hydraulic fittings from a pressurized circuit. Keep fittings and sensor ports clean so dirt or metal particles do not enter the hydraulic system.
After installation, verify the sensor connection, check for leaks, clear stored faults as required, and test the operator through normal travel. Confirm that all monitored external entrapment protection devices, such as photo eyes and safety edges, are installed, connected, and functioning correctly before returning the gate to service.
Professional Advisory
IES sensor replacement can affect the operators inherent entrapment protection behavior. A qualified HySecurity gate technician should handle this repair if the operator has repeated IES faults, hydraulic leaks, pressure issues, unknown prior modifications, or a gate that is binding mechanically.
Do not bypass inherent entrapment sensing, monitored photo eyes, safety edges, limits, hydraulic controls, disconnects, covers, guards, or controller protections to make the gate run. The safety system should be repaired correctly and fully tested before the operator is returned to service.
