Honeywell BZ Series Plunger Limit Switch, SPDT, Plastic Housing, 250V ac, 25A

This limit switch is a Compact electromechanical device designed to detect position changes and control circuits in industrial settings. It operates as a plunger-actuated switch suitable for side mounting and provides a single-pole, double-throw switching arrangement for straightforward control logic. The unit is housed in a plastic enclosure and is intended for use where a robust snap-action contact and simple screw-terminal connection are required.

• SPDT snap-action contact for fast, positive switching
• Rated for 250V AC and 25A to handle mains-level loads
• Mechanical life of 20 million cycles for extended service intervals
• Operates between -55°C and 85°C for wide thermal range use
• 20mm conduit entry enabling standard cable gland fittings

• Suitable for position sensing on conveyor stops and Gates
• Ideal for actuator limit detection in pneumatic systems
• Used with motor control panels to signal end-of-travel conditions
• Can be used for safety interlocks on machinery doors
• Suitable for retrofit in legacy automation assemblies requiring screw terminals

The switch uses screw terminals to secure incoming conductors and simplify installation without specialised tools.

It is designed for side mounting which allows the plunger actuator to be engaged from lateral movement axes.

A 20mm conduit entry accommodates standard conduit glands or threaded cable entries for protected cable routing.

The snap-action contact provides a Rapid changeover, reducing contact bounce and improving repeatable electrical signalling.
