Product catalog summary
Specifications:
The document details a robust pressure switch designed for demanding applications. It features a heavy steel body with high proof and burst pressure ratings, suitable for hydraulic applications prone to pressure shock. The switch is available in various models with adjustment ranges from 15-6000 PSI (1.2-413 BAR).

Electrical Specifications:
The switch supports electrical ratings of 5A [12/24 VDC, 125 VAC] or 3A [250 VAC], with optional 10A or gold contact configurations. It uses a snap action micro switch and offers protection under DIN 43650A (18 mm): IP65.

Temperature and Material Specifications:
The media temperature range varies by diaphragm material: Nitrile (-20°F to 180°F), Viton (23°F to 248°F), HNBR (-20°F to 248°F), and EPDM (-20°F to 248°F). The ambient temperature range is -40°F to 180°F. The housing is made of zinc-plated steel, with an optional stainless steel variant.

Mechanical Specifications:
The switch has a mechanical life expectancy of 1,000,000 cycles at 1000 PSI (69 BAR) and a maximum overpressure of 12000 PSI (827 BAR). Repeatability is +/- 2% of the full set point range at 20°C (68°F), with a differential of 7-30% of the setting.

Applications:
Suitable for industrial equipment, scissor lifts, presses, and cranes.

Ordering Information:
The document provides a detailed ordering guide, including pressure selection, thread options, circuit type, electrical termination, and optional features such as diaphragm material and contact type. Models are available in factory preset or field adjustable configurations.

Wiring Code:
The switch uses a DIN 43650 type contact with common, normally closed, and normally open pins.
