PSM-PSP

Product catalog summary

General Specifications:
The PSM-PSP series are adjustable pressure switches with SPDT contacts and adjustable hysteresis. They support a maximum voltage of 250 Vac and a current of 6 (2) A. The hysteresis is adjustable between 10% and 30% of the set-point. The operating temperature range is from -30°C to +140°C, depending on the diaphragm/gasket material. The switches have a mechanical life of 106 cycles and are protected under IP 65 standards.

Technical Data:
The pressure switches are available in diaphragm (PSM) and piston (PSP) types. The diaphragm type has a maximum cycle rate of 120/min at 25°C, while the piston type has a rate of 60/min. The recommended tightening torque is a maximum of 5 Kgm.

Materials and Options:
The body materials include brass, zinc-plated steel, and stainless steel (AISI 316). Diaphragm materials vary from NBR, HNBR, FKM, silicone, neoprene, EPDM, to stainless steel. Thread options include BSPT, BSPP, NPT, and metric threads. Additional options include snubbers, gold-plated contacts, degreased for oxygen use, and specific set-point adjustments.

Compliance and Testing:
The products comply with the 2004/108 CE EMC standards. Users are responsible for verifying the suitability of the products for specific applications, including material compatibility and field testing.

Ordering Information:
The ordering code includes the model type (PSM or PSP), options, body material, diaphragm type, and pressure range. Example: PSM 10 W V R18 T5D indicates a diaphragm pressure switch with specific configurations.

Electrical Connections and Protection:
The switches offer various electrical connections, including DIN 40050 and M12 connectors, with IP 54, IP 65, and IP 67 protection levels. They support power supplies from 12 V to 250 V and currents up to 6 A.
