Honeywell Series BX Limit Switch, Roller Lever Actuator, IP67 - BX4A3K-1A
This limit switch is a Compact electromechanical device designed to detect and interrupt mechanical motion in industrial control systems. Intended for use in harsh or hazardous environments, it provides reliable actuation via a roller lever and is suited to automation, electrical and mechanical installations where robust switching and environmental protection are required.
Features and Benefits:
• SPDT snap‑action contact providing swift changeover under load
• Rated switching performance at 600V AC and 6 A for AC loads
• Enclosure offers ingress protection to IP67 for wet conditions
• Aluminium housing reduces corrosion in industrial settings
• Operates reliably between −40 °C and +70 °C across environments
• Actuation torque of 0.45 N·m delivers consistent mechanical response
• Rated switching performance at 600V AC and 6 A for AC loads
• Enclosure offers ingress protection to IP67 for wet conditions
• Aluminium housing reduces corrosion in industrial settings
• Operates reliably between −40 °C and +70 °C across environments
• Actuation torque of 0.45 N·m delivers consistent mechanical response
Applications
• Suitable for conveyor end‑of‑travel detection in factories
• Ideal for valve position sensing in process plants
• Used for safety interlocks on industrial doors and guards
• Can be used for actuator feedback in heavy machinery
• Used with control panels where high‑voltage switching is required

What Terminal entry is provided for cable connection?
A single M20 threaded Terminal entry permits secure cable gland or conduit fitting for industrial wiring.
How does the contact arrangement affect system wiring?
The single‑pole double‑throw layout enables a single input to switch between two circuits for both make and break functions.
Is the enclosure suitable for explosive atmospheres?
It carries ATEX and IECEx approvals indicating suitability for certain classified hazardous areas when installed in accordance with applicable regulations.
What construction material aids mechanical durability?
The body is machined from aluminium, offering mechanical strength while keeping weight moderate for mounting on assemblies.
