S2TAF / S3TAF

Product catalog summary

Specifications
The document details the specifications for the S2TAF and S3TAF temperature switches. These switches are designed for hydraulic reservoir safety and coolant temperature applications. They feature a bimetal switch type with a temperature range of 77°F to 293°F (25°C to 145°C) and a temperature differential of 25°F (12°C). The housing material is brass, with an optional stainless steel variant. The S2TAF models have a maximum overpressure of 5000 PSI (345 BAR) for 4M and 6M models, and 2000 PSI (138 BAR) for 8M and 8S models. The S3TAF models support up to 5000 PSI (345 BAR).

Electrical Specifications
The switches operate at 120 VAC - 15A resistive, 240 VAC - 10A resistive, 12VDC - 12A resistive, and 24 VDC - 6A resistive. They offer protection ratings of IP65 for DIN 43650A, IP00 for terminals, and IP67 for flying leads and Deutsch DT04-2P connectors.

Features
The switches are factory preset, compact, and have a high current rating with reliable differential. The S2TAF model features an internal sensing cavity, eliminating the need for a probe, making it suitable for tight spaces. The S3TAF model is ideal for high amperage ratings with high ingress protection.

Dimensions and Construction
Dimensions are provided in millimeters, with a surface finish of 3.2 micrometers. Tolerances are specified as linear: 0.X +/- 0.25 mm; 0.XX +/- 0.12 mm, and angular: +/- 0.5 degrees. The document emphasizes the importance of cleaning and packing parts to avoid damage during overseas shipping.

Ordering Information
Ordering involves selecting the temperature set point, thread options, circuit type, and electrical termination. The temperature set point is in increments of 5°F, with options for rising or falling temperature. Thread options include various NPT and BSPP sizes, with additional options available upon request. Circuit options include SPST (Normally Open or Closed), and electrical terminations vary between DIN connectors and flying leads with different connector types.

Catalog excerpts

S2TAF / S3TAF DESCRIPTION The S2TAF is a bimetal temperature switch featuring an internal sensing cavity that allows for sensing of the fluid temperature without the need of a probe. It is most suitable for where areas is a tight constraint. The S3TAF temperature switch is ideal for high amperage rating with high ingress protection.
