About SBM-Metal 40mm
Pull wire limit switches AAA Operation in traction and release
Limit switches with rope for simple stop, without manual reset. These limit switches are useful for signalling and for commanding doors or similars. Available also in special version with double signal in traction or release, helpful to signal an eventual loss of tension due to the breaking of the rope.
Durability and Build QualityConstructed from high-grade stainless steel with a brushed finish, the SBM-Metal 40mm pushbutton switch offers excellent resistance to corrosion, making it suitable for demanding environments. Its design ensures longevity, with an impressive mechanical life of at least 1,000,000 operations and IP65-rated protection against dust and water exposure.
Electrical Performance and SpecificationsThis switch is optimized for industrial use, supporting up to 415V AC and a maximum current of 10A. It features silver alloy contacts for reliable conductivity and a contact resistance of no more than 50 m. The insulation resistance is rated at 100 M, ensuring safe handling of high voltage and current in manual automation settings.
Versatile ApplicationsEngineered for manual operation, the SBM-Metal 40mm is ideal for panel-mounted controls in machinery, electrical panels, and commercial equipment. Its momentary action, SPST circuitry, and sturdy construction make it adaptable across distribution, export, and import operations, especially for those seeking standards-compliant solutions in Italy and beyond.
FAQ's of SBM-Metal 40mm:
Q: How is the SBM-Metal 40mm pushbutton switch installed?
A: The SBM-Metal 40mm is designed for easy panel mounting. It fits a 25 mm diameter cutout and features solder lug terminals for secure electrical connections. Simply insert the switch through the panel cutout and fasten it in place, then connect the wires to the solder lugs.
Q: What standards and certifications does the SBM-Metal 40mm comply with?
A: This pushbutton switch is CE certified, ensuring compliance with European safety and quality standards. Its IP65 rating guarantees protection against dust and low-pressure water, making it suitable for both indoor and outdoor use.
Q: When should I select a non-illuminated, momentary pushbutton switch like this model?
A: Non-illuminated, momentary switches like the SBM-Metal 40mm are ideal for applications where temporary circuit activation is needed-such as start, stop, or reset functions-without the requirement for visual status indication.
Q: Where is the SBM-Metal 40mm commonly used?
A: This switch is widely used in industrial control panels, automation equipment, machinery, and commercial installations. Its rugged design and international certifications make it suitable for use by distributors, exporters, importers, suppliers, and traders, particularly in the Italian market.
Q: What benefits does the silver alloy contact material provide?
A: Silver alloy contacts offer excellent electrical conductivity and enhanced resistance to arcing and wear. This feature ensures low contact resistance (50 m) and contributes to the long mechanical and electrical life of the switch.
Q: How does the IP65 protection level benefit the user?
A: An IP65 rating means the switch is dust-tight and protected against water jets. This makes it reliable for use in environments exposed to dust, moisture, or periodic cleaning, reducing the risk of failure due to environmental factors.
Q: What is the typical usage process for this switch in automation systems?
A: To operate the SBM-Metal 40mm, the user simply presses the flat actuator for temporary contact closure. Its quick response time (20 ms) allows for immediate action, and the manual reset ensures safety and control in automation circuits.
