Ambient humidity	35% to 85% (with no condensation)
Weight (packed state)	Approx. 150 g		Approx. 200 g

*1. Connection is not supported for Pre-wired Amplifiers (e.g., E3X-DA11-N) and water-resistant Amplifiers
       (e.g., E3X-DA11V).*2. Connection is supported for products manufactured on or after the date shown below (indicated with the lot number).
       Connection is also supported for models with "MADE IN JAPAN" on the cover underlined.

*3.Manufacturing of the E3X-DA[]TW Series was discontinued at the end of March 2012. Manufacture of the
     E3X-DA6/DA8/DA6-P will be discontinued in March 2017.
*4. Does not include the current supplied to the Fiber Amplifier.

Terminal-block Unit

Model	E39-TM1
Power supply voltage *1	12 to 24 VDC ±10%, ripple (p-p) 10% max.
Sensor power supply	11 to 23 VDC (power supply voltage -1 V)
Current consumption	40 mA max. + Sensor current consumption (total: 100 mA max.)
Response speed	1.2 ms max.
Number of inputs	1 point
Input signals	NPN/PNP no-voltage input (contact and non-contact), switchable
Input operating configuration	N.O./ N.C., switchable
Indicators	Input signal display (orange)
Ambient temperature *2	Operating: Groups of 1 to 3 Units: -25 to 55°C (with no icing or condensation) Groups of 4 to 8 Units: -25 to 45°C (with no icing or condensation) Groups of 9 to 16 Units: -25 to 40°C (with no icing or condensation) Storage: -30 to 70°C

*1. The power supply for the E39-TM1 is provided from the Communications Unit (order separately). Use an E3X-CN02
       (order separately) Connector.
*2. When 4 or more Units are grouped together, the current consumption per Unit must not exceed 75 mA.
       When using together with the E3X-DA-N Fiber Amplifiers, connect the E39-TM1 Units at the end of the group.
       In this case, the upper limit for the ambient temperature for the E3X-DA-N Amplifiers is the rated upper limit -5°C.
