Cleanroom Doors, Windows and Interlock Systems
Cleanroom Electric Drop Bolt Lock
A concealed solenoid-operated bolt that projects into a matching keeper after the cleanroom door reaches its aligned closed position.
- Concealed Mortise Body
- Hardened Stainless Bolt
- Door Alignment Tolerance
- Bolt Status Feedback
Product Introduction
This electric drop bolt is recessed into the cleanroom header, frame or door leaf so only narrow stainless faceplates remain visible. A position input prevents premature projection, then the solenoid drives a hardened bolt into the keeper to secure the closed opening. Monitored versions can report both door alignment and bolt position, making the lock suitable for automated access sequences where a compact hidden mechanism is preferred.
Key Features
The narrow mortise body fits aluminum cleanroom frames without a bulky external lock case.
Door-position and bolt-position contacts support separate closed and locked indications.
A controlled re-lock delay can accommodate door rebound before the bolt projects.
Customer Product Concerns
A concealed bolt must tolerate normal door movement while avoiding projection against a misaligned keeper.
A bolt that fires before the leaf settles can strike the keeper edge and jam.The lock uses door-position input and an adjustable delay before extension.
External lock cases disrupt the clean lines of a narrow aluminum frame.The solenoid body is mortised behind a slim stainless faceplate.
Maintenance staff need to know whether the bolt actually reached the locked position.A dedicated bolt monitor reports full extension independently of the door contact.
Typical Applications
Interlocked swing doorsAutomatic sliding cleanroom doorsRestricted laboratory roomsHigh-value controlled storage
