The VTBS3000 is a fixed set point vacuum switch that converts vacuum pressure signals into electrical output via an elastomeric diaphragm, providing SPST or SPDT switching logic. It features a durable thermoplastic construction with an EPDM diaphragm, a 1/8" NPT male pressure fitting, and 1/4" male quick connects. The switch operates at vacuum set points from -0.8 PSI to -5 PSI (-5.51 kPa to -34.47 kPa), with a maximum negative pressure rating of -6 PSI. It is rated for 21 A resistive at 125 VAC and 16 A at 250 VAC, with a 100,000 cycle life under full mechanical, electrical, and thermal loads. The unit is UL recognized for use as an operating, limit, or safety control in the United States and Canada, and operates reliably between 70°F and 160°F (21°C to 71°C).
Series 3000 pressure switches convert a pressure signal to an electrical output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. . .
