Honeywell Series BA Micro Switch, 20mm Conduit Entry, SPDT Contact Configuration - BA-2RQ1-A2

This micro switch is a plunger-actuated control device designed for industrial control and detection tasks. It provides a single-pole, double-throw contact arrangement and is intended for side-mounted installation where compact, repeatable switching with positive snap action is required.

Features and Benefits:

• Snap-action contacts deliver Rapid state change for precise control
• Mechanical life of 20000000 cycles reduces maintenance intervals
• Operating temperature range -55°C to 85°C enables harsh environment use
• Operating force of 6.12 N offers predictable actuation feel
• Screw terminals allow secure field wiring connections
• Conduit entry sized 20mm supports standard cable glands

Applications

• Suitable for limit switching on automated production equipment
• Ideal for safety interlocks in electrical cabinets
• Used for position sensing in mechanical actuators
• Can be used for signal changeover in control panels
• Suitable for replacement in legacy industrial controls

What material protects the internal mechanism from the environment?

The body is manufactured from plastic which provides Basic insulation and mechanical protection for the internal components.

How is the device mounted to a panel or assembly?

It is intended for side mounting, allowing attachment where lateral access is required for actuator engagement.

What termination method is provided for electrical connections?

Termination is via screw-type terminals that permit robust conductor clamping and straightforward on-site wiring.

Does the unit carry hazardous-area certification for explosive atmospheres?

No hazardous-area certification is provided for this device, so it should not be used where such approvals are mandatory.

What approval or standard applies to material restrictions?

The switch conforms to RoHS requirements limiting certain hazardous substances in its construction.
