HA41A6B212
The HA41A6B212 is a precision reset timer produced by Danaher as part of their Timers and Controllers series, offering reliable performance in industrial automation environments. This panel-mounted device features a 0–60 second timing range displayed on an analog dial with fine resolution, and utilizes a 120 V AC input at 60 Hz for power. The unit employs a robust encapsulated coil rated at Coil Voltage: 12 VDC and Coil Resistance: 320 Ω, delivering consistent timing cycles through a motor driven cam mechanism with spring return. With a compact footprint and Plug-in mounting type, it weighs About 35g, making installation and replacement straightforward. The DPDT contact arrangement and optional SPDT contact configuration support a Contact Rating: 10A at 250VAC / 30VDC, ensuring compatibility with a broad range of control circuits.
Technical capabilities of the HA41A6B212 are defined by a combination of electrical robustness and mechanical endurance. The Dielectric Strength: 2000VAC, 1 min between coil & contacts and Insulation Resistance: 1000 MΩ min (at 500VDC) provide excellent isolation under demanding conditions. The device achieves a maximum Operate Time: 15 ms and a Release Time: 10 ms, delivering precise repeatability and minimal timing error. Its Electrical Life: 1,000,000 operations and Mechanical Life: 10,000,000 operations ratings attest to its durable design. The open-frame architecture and high dielectric Bakelite terminal base combine with a steel mounting frame and molded plastic control face to resist thermal and electrical stresses.
Operational features include a locking timing adjustment knob that prevents inadvertent changes during vibration or shock. The analog dial scale offers clear, graduated markings for setting intervals within the 0–60 second timing range, while the spring-return cam mechanism ensures reliable reset after each cycle. Screw-type contact terminals facilitate secure wiring and rapid replacement, while the encapsulated coil protects internal windings against dust and contamination. Designed for dry, enclosed environments, the timer functions across an Ambient Operating Temperature: –40 °C to +85 °C range, accommodating both low-temperature starts and high-temperature processes.
Integration into control panels and machinery is seamless thanks to the Plug-in mounting interface, which simplifies wiring and reduces maintenance downtime. The HA41A6B212 can be paired with PLC outputs, contactors, and relay logic to orchestrate timed events in assembly lines, packaging equipment, and safety interlock circuits. Its DPDT and SPDT contact options support both changeover and single-throw switching schemes, enabling diverse application scenarios. Engineers will appreciate the combination of high contact ratings, rapid operate/release times, and proven life cycles for dependable automation performance.
