Dortronics 5221-P23DA Delayed Action Push Button, Pneumatic Time Delay Push Button Switch

Optimize door control and on-site security with the Dortronics 5221-P23DA Delayed Action Push Button, a pneumatic time-delay push button designed for consistent, tamper-resistant door release. Built by Dortronics, this push button delivers an adjustable timed output (2 seconds to 1 minute) so facilities managers can fine-tune egress timing to prevent unauthorized entry while maintaining smooth throughput. The 5221-P23DA supports 115V AC or 24V DC inputs for flexible integration into access control panels, CCTV monitoring setups, and alarm systems. Constructed from stainless steel in a single-gang format, it withstands heavy use and harsh environments (operating temps from -15°C to 70°C), making it well suited for commercial, institutional, and industrial installations. The pneumatic time-delay mechanism provides a consistent, maintenance-friendly alternative to electronic timers, enhancing reliability for security and surveillance applications. Backed by a one-year limited warranty and US manufacturing, the 5221-P23DA is a practical choice for upgrading door release controls.
