NICE / APOLLO A2005, HW, PROXIMITY LIMIT BOLT
The Nice Apollo A2005 is the proximity limit bolt used in the internal limit/back-housing area of compatible Apollo actuator assemblies. It is one of the small hardware pieces that supports the limit assembly and helps maintain correct positioning of the components that interact with the magnetic proximity switch. This part is commonly ordered when the original bolt is missing, worn, corroded, stripped, or damaged during actuator service. Because the surrounding A2002, A2003P, A2004, A2008, and A2009 parts all work together, the bolt should be matched to the parts diagram rather than selected by appearance alone.
Compatible With
- Apollo 416 swing gate actuators, when the installed actuator uses the matching internal limit/back-housing design
- Apollo 416X swing gate actuators, when confirmed by parts diagram and cable configuration
- Apollo 816 swing gate actuators, including many Apollo 1500, 1550, 1551, and related 816 actuator installations
- Apollo 816X swing gate actuators, when the original part number and rear housing layout match
- Nice Apollo linear actuator back-housing and internal limit tower service assemblies that call for this exact part number

Technician Note
Small limit hardware can cause large limit problems if it is missing or installed incorrectly. Check the original orientation and the full limit tower assembly before replacing only the bolt.
Before Ordering
- Confirm the parts diagram calls for A2005.
- Inspect the limit tower and surrounding block parts for cracks or wear.
- Check the proximity switch and magnetic block at the same time.
- Verify the actuator model and cable configuration.
- Do not substitute a generic bolt if the original hardware controls spacing or movement.
Professional Advisory
Gate operator parts should be installed with the operator powered down and the gate secured against movement. For electrical diagnosis, actuator disassembly, or unsafe gate movement, use a qualified gate technician. Do not bypass required safety devices or use this service part to defeat UL325 safety functions.
Important Ordering Warning
This is a limit assembly hardware part. Incorrect hardware or spacing can affect limit detection and gate travel.
Product Questions & Answers
What is A2005 used for?
A2005 is the proximity limit bolt used in the internal limit assembly area of compatible Apollo actuators.
Is this a complete limit switch kit?
No. It is a hardware bolt only and does not include the proximity switch, blocks, spring, or tower assembly.
Which actuators commonly use this part?
It is commonly associated with Apollo 416, 416X, 816, and 816X actuator back-housing limit assemblies.
Can I use a standard hardware-store bolt?
That is not recommended. The limit assembly relies on proper fit and spacing, so the correct service part should be used.
Should limits be checked after replacing it?
Yes. Any work inside the limit assembly should be followed by a safe limit test and adjustment if needed.
