Product Description:
The PMB31B-20201-03 is manufactured by Pacific Scientific, which is a part of PMB Brushless Servomotors, and is a solid and durable limit switch actuator.
This switch may be used in both normally open and normally closed circuits since it features an actuator, roller lever, and a Single Pole Double Throw (SPDT) contact form. It contains contacts that are composed of silver alloy, high-conductivity, and durable against repeated switching loads. At its rated 250 VAC at 5 A, the switch can carry the normal industrial control voltages and currents. It can be operated with only 1.96 N of force, which qualifies it as sensitive enough to be triggered by light mechanically, yet it has mechanical stability. Its mechanical life expectancy is 10 million operations, and its electrical life is 100,000 cycles; its construction is designed to last long-term under severe operating conditions.
Polybutylene Terephthalate (PBT), a tough, heat-resistant polymer with an IP67 certification grade for dust resistance and transient water soaking, is used to make the housing. The device is capable of handling vibrations up to 10-55 Hz at 1.5 mm dual amplitude and runs in ambient temperatures spanning -25°C to +80°C. It is also capable of withstanding shock loads of up to 1000 m/s², which is approximately to 100G. The unit is compatible with a standard servo motor system and mounting components since it is panel-mounted and fits into a NEMA size 34 frame standard. It is simple and secure to integrate electrical connections with control systems utilizing flying leads and an MS connector. It can be purchased at Wake Industrial with a one-year warranty.
