Pressure Switch hex 24

Product catalog summary

Technical Specifications:
Pressure switches are available in normally open or closed configurations, supporting up to 42 V and 4 Amperes, with a contact rating of 100 VA. Temperature stability varies by diaphragm material: NBR (-40°C to +100°C), EPDM (-30°C to +120°C), FKM (-5°C to +120°C), Silicone (-40°C to +120°C), and HNBR (-30°C to +120°C). They have a switching frequency of 200/min and a mechanical life of 1 million cycles for pressures up to 50 bar. Vibration resistance is up to 10 g, shock resistance up to 294 m/s², with IP65 protection and terminals rated at IP00. The weight is approximately 90 grams.

Design and Features:
Designed for mechanical pressure monitoring, these switches offer stable switching points under high load and long-term use. They are adjustable, compact, factory preset, and RoHS compliant. Available in zinc-plated steel, stainless steel, or brass bodies, they can withstand overpressure up to 600 bar depending on the model.

Applications and Materials:
Diaphragm materials are chosen based on application needs: NBR for hydraulic oils and air, EPDM for brake fluids and ozone, and FKM for hydraulic fluids and gasoline. Suitable for various industrial applications, specific models are designed for gases.

Accessories and Options:
Accessories include rubber protective caps with IP54 protection. Available with M3 screw or spade terminals, they can be customized with different body materials and connecting threads. Ready-wired versions are also available.

Safety and Compliance:
Compliance with safety regulations is essential, especially with oxygen use. The switches are RoHS compliant, and dynamic pressures should be 30-50% lower than static values for safety.

Overview: This document provides technical specifications for diaphragm pressure switches, detailing models, settings, and applications, including pressure ranges, thread types, and diaphragm materials.

Specifications:

Pressure Ranges: Available settings: 0.1 – 1 bar (± 0.2), 1 – 10 bar (± 0.5), 10 – 20 bar (± 1.0), and 20 – 50 bar (± 2.0).
Thread Types: Options include R1/8, G1/4-E, R1/4, M10 x1 con., R1/2, G1/4, and G1/8.
Diaphragm Materials: NBR for hydraulic/machine oil, EPDM for water and brake fluid, and FKM for hydraulic fluids and gasoline.

Procedures and Recommendations:

Available with factory pre-set switching points and ready-wired versions.
Other body materials and connecting threads available upon request.
Dynamic pressures should be 30 to 50% lower than static pressures.

Compliance and Safety:

All models are RoHS compliant.
Brass body models are overpressure safe up to 35 bar.

Applications: Suitable applications for each diaphragm material include hydraulic fluids, water, and gases.
