TS-R

The TouchStart™ is an ergonomic alternative to a mechanical palm button switch. These switches are often used to cycle industrial machinery such as punch presses. Unlike mechanical switches, which can require substantial force to operate, the TouchStart requires no actuation force. It detects the operator’s hand and actuates its output relays with a mere touch of the button.

The design of the TouchStart includes circuitry to prevent false triggering from the presence of Radio Frequency Interference (RFI). The TouchStart has been tested by Underwriters Laboratory and is recognized under Standard UL 491, "Standard for Power Operated Machine Controls and Systems." This is the only UL standard dedicated to operator safety in press control applications. The requirements of UL 491 are in accordance with the following Standards:

• NFPA79 The Standard for Metal Working Tools
• NFPA70 National Electrical Code
• ANSI B11.1 Standard for the Construction, Care and Use of Mechanical Power Presses
• OSHA Section 1910.217

Capacitive Palm Button
• No physical pressure required to actuate switch—reduces the likelihood of wrist injury caused by repetitive motion
• Excellent sensitivity—sensor is designed to operate even if operator is wearing gloves
• RFI Immunity—special circuitry inhibits output in the presence of RFI that would otherwise cause false triggering of output
• AC version is UL Recognized—meets the applicable requirements in the proposed first edition of UL 491
• Saves time and money
• Easy mounting in a single hole.
• Wiring is simplified because terminals are clearly identified and easily accessible.
• No special power supplies are required because switch is available in either 120 VAC or 24 VDC versions.
